| MCB | |
| |
| |
| What does c curve mean? | |
| |
There are 3 curve characteristics for magnetic operation,
| |
| |
 Back to top | |
| |
| |
| How do I select right breaker for fault loop impedance? | |
| |
| First, obtain the cable size and current rating. The MCB is not to be larger than the current rating. Check the table below for the maximum cable length or maximum circuit impedance in order to meet the fault loop requirements. Clause 6.3.4.2.1 of the Wiring Rules refers to optional tests to comply with the fault loop requirements. | |
| |
 | |
| |
| Where: MCL = Maximum circuit length Zs = Maximum circuit impedance Above table based on supply voltage of 230V / 400V (AS/NZS 3000:2000 Amdt 1) | |
| |
| Back to top | |
| |
| |
| What accessories can be fitted? | |
| |
| See page 134 of price book or Protection and Connection section of web site. These include auxiliary contacts (on/off condition), signal contacts (MCB tripped due to fault), shunt trip (remote operation off), undervoltage (35-70% of nominal causes MCB to trip), locking device, and heat dissipation inserts | |
| |
| Back to top | |
| |
| |
| What affect does high ambient temperature have on the operation? | |
| |
| MCBs have thermal/magnetic characteristics. As the current is increased, the heat generated increases to the point where the current and subsequent heat is greater than the calibrated setting - the MCB trips. When placed in high ambient temperatures the calibrated point is lowered, i.e. the rating of the MCB is de-rated. Refer to the table below when installing MCBs in ambient temperatures other than 30°C. | |
| |
 | |
| |
| Back to top | |
| |
| |
| Can I use a hager MCB to protect a dc system? | |
| |
| Yes, maximum voltage is 60Vd.c. using 1 pole or 125Vd.c. using 2 poles. The breaking capacity of the MCB remains the same although the magnetic tripping point is increased by 50% (i.e. a C-curve characteristic is altered from 5 - 10 x In to 7.5 - 15 x In) | |
| |
| Back to top | |
| |
| |
| What does the kA rating of a circuit breaker imply? | |
| |
| All Hager circuit breakers have been subjected to short circuit testing at their marked rating and are capable of successfully interrupting the fault current without undue damage to the circuit breaker. The circuit breaker should not be installed into an area where the prospective fault level is higher than the rating of the circuit breaker (except where cascading is used as a design feature under Cl.2.4.4.3 of the Wiring Rules). Commercial installations and installations close to distribution transformers will have relatively higher fault levels. Consult your energy distributor for the fault level at a given installation. | |
| |
| Back to top | |
| |
| |
| Should I twist the end of a stranded cable before terminating into a Hager MCB? | |
| |
| No. By not twisting the cable, the strands are able to spread out and fill the terminal as it is tightened. This maximises the contact area of the cable to the terminal resulting in a cooler running joint and a stronger connection. Always physically check the strength of a connection after tightening. | |
| |
| Back to top | |
| |
| |
| MCCB | |
| |
| |
| What is cascading and how do I use it? | |
| |
| This principle is defined in the Wiring Rules, Cl 2.4.4.3 and allows a lower fault rated device to be installed downstream and still comply with the fault rating requirements for equipment installed at a particular point. We use this in the design of switchboards to keep size to minimum, costs down and maintain integrity of fault ratings | |
| |
| Back to top | |
| |
| |
| What is discrimination and how do I use it? | |
| |
| This principle is used by supply authorities to ensure continuity of supply, where under fault conditions a downstream device such as an MCB in a switchboard operates, but does not affect the upstream service protective device. We consider this when designing switchboards | |
| |
| Back to top | |
| |
| |
| Can I fit accessories? | |
| |
| Yes, a full range of common accessories fit the h125 – h630 ranges. These include auxiliary, signal, shunt trip and under voltage trip, similar to MCB. Each range has specific handles and barriers etc. The accessories can be retrofitted, the front cover is removed (MCCB trips), no copper/metal parts are exposed. Each range ( h800, h1250, h1600) has a separate selection of accessories and auxiliaries. | |
| |
| Back to top | |
| |
| |
| Can I adjust the current ratings / trip settings? | |
| |
| Yes. h125 / h160 ranges: you can adjust the thermal current setting to either 80% or 100%; the magnetic settings are fixed. The other MCCB ranges (h250, h400, h630, h800, h1250, h1600) are fully adjustable on both thermal and magnetic settings. Design drawings will give the required settings for circuit breakers. | |
| |
| Back to top | |
| |
| |
| What does LSI mean? | |
| |
| This refers to electronic trip units. Long time delay, Short time delay and Instantaneous time delay. This assists with discrimination and fault loop impedance compliance in switchboard design. | |
| |
| Back to top | |
| |
| |
| RCCB/RCBO | |
| |
| |
| What are the trip times for a 30mA RCCB? | |
| |
| Several standards define these times (AS/NZS 61008.1:2004 and AS/NZS 61009.1:2004). At 30mA the trip time must be less than 300ms. Increase the residual tripping current and the tripping time decreases, eg at a residual tripping current of 150mA (5 x IΔn) the RCCB or RCBO must trip in under 40ms. | |
| |
 | |
| |
| Back to top | |
| |
| |
| Every time I turn a switch on in the house the RCCB trips, why? | |
| |
| First check the RCCB by disconnecting the load cables and operate the test button. If it works, the RCCB is OK. Ensure neutral cables correspond to active cables. There may a crossed neutral, ie the current flow in active and neutral is not equal, thus tripping occurs. | |
| |
| Back to top | |
| |
| |
| The test button does not work, but when I connect a load the RCCB trips? | |
| |
| Check the RCCB by disconnecting load cables and operate the test button. If it works, the RCCB is OK. Perform a Megger test N-E on the load side wiring. The result should be not less than 1M Ohm (Wiring Rules Cl 6.3.3.3). If the result is a low Mohm reading, look for a pinched conductor, nails through cables or an unterminated cable. | |
| |
| Back to top | |
| |
| |
| I have 2 RCCBs installed and when I operate the test button on one the other trips, why? | |
| |
| Neutral conductors could be incorrectly terminated or common neutrals on the load side of the RCCBs. Each RCCB requires its own load side neutral link, eg Hager part number: KM03A. | |
| |
| Back to top | |
| |
| |
| Does the installation of an RCCB affect fault loop impedance? | |
| |
| Yes. The Wiring Rules require a protective device to operate in not more than 400ms under earth fault conditions. An RCCB always operates in less than 300ms and so meets the earth fault requirements. When conducting an earth fault loop impedance test, an internal connection is made by the test instrument which causes an RCCB to trip. Therefore the fault loop test is satisfactory (see Cl 6.3.4.2 of the wiring rules). | |
| |
| Back to top | |
| |
| |
| What is a Type A device? | |
| |
| Type A defines an RCCB which is sensitive to both ac and pulsating dc sine waves, mandatory in medical / dental patient treatment areas and in New Zealand. Recommended for welding machine protection where a d.c. offset may be used by the machine operator (a d.c. offset may saturate the differential relay of a standard Type AC RCCB and it may not trip when required). Type AC RCCBs are sensitive to a.c. sine waves only. | |

| What size cables can I pass through the toroids of earth leakage relays? | |
| |
 | |
| |
| Back to top | |
| |
| |
| Can I connect a Hager RCD to a d.c. supply? | |
| |
| No. Hager RCCBs and RCBOs are not suitable to be connected to a d.c. supply. | |
| |
| Back to top | |
| |
| |
| How many computers can I connect to a 30mA RCD protected circuit? | |
| |
| The switch mode power supply in a computer will leak up to 3.5mA to earth. A Hager 30mA RCD will not trip at 15mA but will trip at a point above 15mA and below 30mA. We would suggest no more than 4 computers on the one RCD circuit in order to ensure that unwanted tripping of the RCD does not occur. | |
| |
| Back to top | |
| |
| |
| What are the earth leakage currents of other typical devices? | |
| |
| Lighting appliances, hand held tools and portable appliances, other household appliances and laptop computers typically leak around 1mA or less to earth. Heating elements and water heaters will leak higher currents to earth and may cause unwanted tripping of RCDs. | |
| |
| Back to top | |
| |
| |
| What are the possible causes of unwanted tripping of RCDs? | |
| |
| Transient voltages on the supply, Cumulative leakage from appliances, RCD too sensitive for the application, moisture ingress or condensation, old appliances with failed insulation (particularly fridges and freezers), MIMS cables, Heating elements, Crossed neutrals within the installation, capacitance from long cable runs, interference from walkie talkies | |

| SURGE PROTECTION DEVICES | |
| |
| |
| After a recent storm customers rang to say their electrical products do not work any more, I want surge protection, help. | |
| |
| We recommend you download the Surge protection devices .pdf file, or contact your hager B&R representative for further assistance | |
| |
| Back to top | |
| |
| |
| Why is an MCB required before the surge protection device? | |
| |
| Surge Protection Devices do not generally have short circuit protection inbuilt and in some circumstances can continue to remain closed circuit after the metal oxide varistor (active component) has expired. This process is called thermal runaway, resulting in an active to earth short circuit. The MCB interrupts this flow, providing additional circuit protection. | |
| |
| Back to top | |
| |
| |
| What size earth conductors should be used? | |
| |
| We recommend you size the earth conductor (for the connection from the medium surge device [SPN115/140/165] to the earth link) to the same as the main earth, eg 6mm for domestic | |
| |
| Back to top | |
| |
| |
| How do I protect computer and home theatre circuits? | |
| |
| The devices connected to these circuits are very sensitive. By connecting a fine device SPN208S (in series with circuit MCB or RCBO) in conjunction with a medium SPD (SPN115 / 140 / 165), enhanced protection is provided. The medium SPD will divert a surge up to 65kA leaving a residual voltage of 1.0 - 1.5kV. These voltage levels are still too high for sensitive equipment so the next step is to limit this voltage to 800V. This is achieved with the use of the Class II Fine devices (SPN208S and SPN408S) which have a lower current carrying capacity, but will limit the voltage to 800V. Using both SPD devices is called cascading. Cascading increases the current diverting capacity of our SPD system whilst maintaining a low residual voltage to ensure the best protection for valuable equipment. | |
| |
| Back to top | |
| |
| |
| What other factors can I use to promote surge devices? | |
| |
| Obtain the hager B&R risk assessment calculator from your Hager B&R representative. When discussing surge protection with clients, identify their electrical capital equipment at risk. Point out that insurance is difficult to claim without physical proof of a direct lightning strike. Use testimonials from other customers | |

| |
| LOAD BREAK SWITCHES | |
| |
| |
| What is the difference between load break and isolator switches? | |
| |
| Load break switches are intended to close on full load current and open on full load current. The switch contacts open/close rapidly in a wiping motion that cleans contacts. Isolator switches are intended to operate on no load. | |
| |
| Back to top | |
| |
| |
| Do I need to consider fault ratings during design of an installation? | |
| |
| Yes, the load break needs to be able to withstand the forces generated by a fault until a protective device operates. So the peak withstand rating of the switch should be less than or equal to the peak let through level of the largest protection device in series with the switch. | |
| |
| Back to top | |

| |
| When should I use a load break switch versus isolator versus CFS? | |
| |
| |
| |
| Back to top | |
| |
| |
| What does AC22, AC23 mean? | |
| |
| AC22 - switching of mixed resistive and inductive loads including moderate overloads AC23 - switching of motor loads or other highly inductive loads | |
| |
| Back to top | |
| |
| |
| ISOLATOR SWITCH | |
| |
| |
| What is the difference between an isolator and an MCB? | |
| |
| The Isolator has red toggle with manual operation ON/OFF. The MCB has a grey toggle and is marked with a kA rating on it’s front face. The MCB has automatic operation OFF under overload or short circuit conditions. | |
| |
| Back to top | |
| |
| |
| METERS | |
| |
| |
| I have a 3 phase installation and want to monitor voltage and current. How do I do this? | |
| |
| Digital or analogue meters are available (discuss with your client their needs). You will also need selector switches for voltage and amperes. You will need CTs for the ammeter appropriate to the max demand of the installation. | |
| |
| Back to top | |
| |
| |
| Do I need to calibrate kWh meters? | |
| |
| Yes. The meter does not know the CT ratio you have connected. Please download the user instruction sheet for this procedure. Failure to calibrate will result in incorrect readings. | |
| |
| Back to top | |
| |
| |
| Are Hager CTs sensitive to the direction of current flow? | |
| |
| No. Hager Ammeters and kWh meters measure the magnitude of current only. The polarity of their installation is not critical. | |
| |
| Back to top | |
| |
| |
| How do I know how accurate the kWh reading will be? | |
| |
| The accuracy of the final installation depends upon the CTs used as well as the length and size of connecting cables. Download and refer to the tables on page 9 of the Control Equipment & Systems technical section, “Accuracy of a kWh meter installation”. | |

| |
| CONTACTORS | |
| |
| |
| Why do I need to use a contactor? | |
| |
| A contactor is another form of switch operated automatically. Its rating should be matched to the size and type of load it is controlling. The use of a contactor allows the reduction in size of the contacts in a control device (eg time switch). | |
| |
| Back to top | |
| |
| |
| What is the utilisation category of the 25A contactors? | |
| |
| The 25A contactors are approved to IEC 61095 with utilisation category AC-7a. AC7a allows for slightly inductive loads in household appliances and similar applications. The power factor of the load can not be less than 0.8. | |
| |
| Back to top | |
| |
| |
| I have noticed Hager 25A contactors are rated, eg “25A Ith”, what does this mean? | |
| |
| Ith is the conventional free air (unenclosed) thermal current used for temperature rise tests. It does not allow for making and breaking. | |
| |
| Back to top | |
| |
| |
| What load can the 25A contactors make and break? | |
| |
| The make and break current is referred to as the rated operational current (Ie). The ES220 25A contactor can make and break 20A (AC7a – slightly inductive loads in household appliances, power factor greater than 0.8) given a rating of 4kW with voltage = 250Va.c. | |
| |
| Back to top | |

| How much current can be loaded onto each pole of a 4 pole 40A contactor? | |
| |
| Each pole is fully rated at 40A AC1 | |
| |
| Back to top | |
| |
| |
| What does AC1, AC3, etc mean? | |
| |
The 40A and 63A contactors are tested to IEC 60947.4.1. AC1 and AC3 are utilisation categories or switching capabilities of load types, taken from this standard:
| |
| |
| Back to top | |
| |
| |
| Why would I use a latching relay? | |
| |
| A latching relay is another form of switch operated automatically from a pulse input voltage. Each pulse will switch the state of the contacts ON/OFF. Latching relays are used where the input control is a push button or the pulsed output from a timer. The maximum length of time for the input pulse is 1 hour. | |
| |
| Back to top | |
| |
| |
| TIME CLOCKS | |
| |
| |
| Can I switch a 16A load on timer contacts rated at 16A | |
| |
| In theory yes, in practice NO. We do not advise this. We do not know what loads are being connected, therefore, it is safer to use a contactor to switch the load and not the relatively expensive timing device. | |
| |
| Back to top | |
| |
| |
| I want to operate a school bell, but only during school hours, not weekends, holidays | |
| |
| A Hager EG400 time clock is the only device that will comply with this application. We recommend programming with the supporting software EG003U, a computer based programme that enables easy programming of EGxxx series time clocks. The programme is entered into the computer and then downloaded onto the key supplied with the clock. This enables easy storage and modification of programmes. | |
| |
| Back to top | |
| |
| |
| I have installed an EG103E and now the time is one hour out due to daylight savings. Do I have to re-programme the time clock? | |
| |
| You will need to adjust the actual time to suit. The programme is in relation to the actual time. We have introduced a new version of this model (look for V2 on the packaging) that has daylight savings dates pre-set for Australia. During initial setup, select the “AUS” option - See your user instruction sheet or download a copy. | |
| |
| Back to top | |
| |
| |
| How can I secure the time clock program from tampering? | |
| |
| EG103E and EG203E time clocks can be electronically locked to prevent programme changes. This is optional. Only you can then unlock the clock and re-program. | |
| |
| Back to top | |
| |
| |
| EG071 - Why isn't the time clock switching according to my program? | |

| |
| TIME DELAY SWITCHES | |
| |
| |
| I want a device to turn lights off, 5 minutes after I turn the light switch off. How do I do this? | |

| We launched a product called Infinity for this very application. Infinity is a range of modular cabinets with IP34, IP55 or internal IP20 frames that can be fitted with a range of mounting pans and chassis to suit the hager range of devices up to 630A. This includes CT metering, whole current metering and check metering. We also offer a complete system design from the main board, panel boards, distribution boards, modular devices and wiring accessories. Please speak to your Hager B&R Representative who can prepare a project quote for you. | |

| |
Several options to be considered:

| |
| |
| Do I need to consider the fault rating of the chassis? | |
| |
| Yes. The chassis has been tested at 18kA for 0.2 of a second. A protective device needs to be installed prior to the chassis in order to interrupt supply to the chassis in the event of a fault. The peak let though current of the protection device must be less than 36kA to prevent damage. A Hager 250A MCCB installed at a prospective short circuit current of 30kA has a peak let through of 27kA, thus satisfying the requirement. | |

| |
| |
| Which way do Hager MCBs fit on to the chassis? | |
| |
| Hager MCBs must be fitted with the DIN clip facing towards the centre of the chassis (the DIN clip can be removed if a hazard is considered to exist, eg live connection). This orientation places the exhaust port of the MCB away from the chassis. Also, the single module RCBO can only be mounted with the DIN clip facing toward the chassis. These chassis are not designed to suit other brands of MCB. | |

| |
| |
| What material are the plates and rockers made from? | |
| |
| Front plates and the external surface of rockers are all made from UV stabilised, Hi impact Polycarbonate. All mounting blocks are also made from the same material to allow for the best possible colour matching. It is important to note that internal parts of the dual injection rocker and pivot points are from chemically resistant ABS. This aids in prolonging the life of the switch from the use of domestic/commercial cleaning products | |

| What is the difference between duct and trunking? | |
| |
| As defined by the Wiring Rules (Clause 1.4.39), a duct is a pipe of 75mm diameter of greater. Trunking (Cl 1.4.89) houses and protects electrical cables and conductors. These definitions have been in place for several editions of the Wiring Rules. | |
