Circuit Breaker Auxiliaries

Functions

Tripping and indication auxiliary contacts are common to the range of

multi-pole 10kA MCBs, and RCCBs. They should be mounted on the

left hand side of the device.

Auxiliary Contact MZ201 (Fig 9)

Allows remote indication of the status of the device contacts to which

it is associated.

Auxiliary Contact and Alarm Contact MZ202

This accessory has two separate functions. Like the MZ201 auxil-

iary contact, however the alarm contact will provide indication if the

breaker trips under fault conditions.

MZ201 Auxiliary Contact and Alarm Contract

MZ203 Shunt Trip*

Allows tripping of the device by feeding the coil. The contacts also

allow for remote indication of operation.

MZ206 Under Voltage Release* (Fig 10)

Allows the MCB to trip when the voltage drops or by pressing a

remote off switch (i.e. emergency stop).

* Indication that the product has tripped due to the voltage release is

provided by a ag on the product. 

Grouping / Combination of Several Auxiliaries

On 2, 3 and 4 pole MCBs it is possible to associate 3 auxiliaries –

2 indication auxiliaries and 1 release auxiliary. In this case, it is important to rst x the indication auxiliary (MZ201 and MZ202) and then the  

release auxiliary (MZ203 and MZ206).
