Selection of circuit-breakers without overload releases for use in combination with ZWA electronic motor-protective relays:The tripping response of the ZWA motor-protective relay is matched by setting of the tripping class (CLASS), to the starting behaviour of the motor to be protected. Where a relatively long tripping response time is selected, a circuit-breaker with a higher rated operational current

Ie must be used in order to prevent thermal overloading of the switch. The appropriate rated operational current

Ie must be calculated using the following factors:

ZWA tripping Rated operationalclass setting current

Ie of the NZM circuit-breaker= Rated motor current

Engineering notes Safety switches with load shedding and indication (example)Maintenance and safety switches have the same electrical function. They are designed to isolate electrical installations (loads) safely from the mains while maintenance work or repairs are being carried out, thereby ensuring that no hazard arises to personnel, machinery or product.The safety switch is an additional, enclosed main switch = isolator for an individual electrical load, and can be fitted directly next to the motor or the electrical load, ensuring that work on them can be carried out safely, provided the 5 safety rules to VDE 0105 are observed. This is of special importance if there is any possibility whatsoever of the main switch being wrongly identified.

ApplicationBy securing the switch in the Off position with his own padlock (up to three can be fitted), the fitter/electrician can protect himself against the possibility of any other person switching On the machine without authority.Maintenance switches are merely additional, enclosed main switches with a padlocking facility.

FeaturesSafety switches are housed in insulated enclosures as standard and bear the inscription 'Safety Switch' on a bright orange label. Labels in other languages are available.Switches to be used for Emergency-Stop switching have a special red handle and a yellow locking collar in accordance with STOP category 0 to IEC/EN 60 204.If the switch is not admissible for use as an Emergency-Stop switch, both parts are grey.The cover and handle are interlocked when a padlock is in place.

Selection:Switches must be selected according to the following criteria:1) The motor switching capacity, where the switch is

fitted in such a way that the operator may use it for operational On and Off switching.

2) The motor rating applies for 3 poles as standard. Where the motor rating is divided between 6 poles, such as for star-delta starting, the 1.73 fold rating can be controlled with a 6-pole switch.

3) The uninterrupted current, where the switch has a load-shedding contact (LA). The load-shedding contact is an auxiliary contact, which is closed in the On position and opens early when switching Off, so that a contactor in the circuit takes over the switching capacity, and the maintenance/safety switch operates at zero load. When switching On, the LA closes later than or at the same time as the main contacts. This is achieved by the series connection of an early-make auxiliary contact (VHI) and a standard auxiliary contact (NHI).

4) The uninterrupted current, provided that the switch is safely prevented from switching under load.

5) This can be achieved for example, by padlocking the handle (which may need to be changed accordingly) in the On position.This is not admissible for switches with a red/yellow handle.

Incoming circuit-breakers

Outgoing circuit-breakers

Selectivity between circuit-breakers enables the isolation of faulty system sections. Incoming breaker 1 and outgoing breaker 2 operate selectively if, in the event of a short

circuit at position 2 only outgoing breaker 2 trips out. System sections 3 and 4 remain operational.

Selection: Incoming circuit-breaker NZM standard circuit-breaker, then the selectivity limits apply as given. Incoming circuit-breaker NZMS, NZMH breaker, then the high-capacity current limiting breaker

enables a higher selectivity limit to be achieved.The values in brackets apply in this case. Where an NZM standard circuit-breaker is used as outgoing circuit-breaker, the selectivity limit

is reduced to the response current of the short-circuit release in the incoming circuit-breaker.

Table 3

Protection of PVC-insulated cables against thermal overload in short-circuit conditions.

In accordance with the IEE Wiring Regulations, cables and conductors must be protected against overloads and short circuits.In NZM, NZMS and NZMH circuit-breakers, overload protection is provided by adjustable, inverse time-delayed overload releases.

Short-circuit protection is provided by adjustable short-circuit releases that open the main contacts in less than 25 ms. The short total operating delay restricts the temperature rise in the conductors to a minimum.

Tables 1 and 2 show the minimum cross-sections reliably protected by NZM(S, H) circuit-breakers in the event of a short circuit. (operational voltage

UN = 380 500 V)

Where the prospective fault current at the point of installation of circuit-breakers is very high, it is conventional to use NZMH current-limiting circuit-breakers having a switching capacity of 100 kArms .An economic alternative to this is to fit one NZMH current-limiting circuit-breaker upstream of the point

in the network where the fault level is too great for the switching capacity of downstream NZM standard circuit-breakers.Table 3 shows which NZMH current-limiting circuit-breakers will, when used in combination with downstream NZM standard circuit-breakers, provide positive protection network points having prospective fault levels of 100 kArms.

The selectivity limit is determined by the response current of the short-circuit release in the upstream circuit-breaker . In many applications, this is sufficient.
