Auxiliary contact for AZ, AZ-XHI11 series circuit breakers 212067

Auxiliary contact for overcurrent circuit breakers – expanding the functionality of the installation

This auxiliary contact, designed for the AZ and AZ-XHI11 series of circuit breakers, is a key element for expanding and adapting electrical protection. It allows you to add additional signaling or control circuits, which is particularly useful in more complex installations. Compact dimensions – only 0.5 module wide – allow for easy integration with existing switchboards, without taking up valuable space.

Versatility and compatibility

The contact is universal and compatible with various configurations of circuit breakers from the AZ series. It has one normally open contact (1NO) and one normally closed contact (1NC), providing flexibility in connecting various signaling or control devices. The rated voltage of AC 230V ensures wide application in typical electrical installations. The rated switching current of 3A allows operation of low-power loads, ideal for signaling the status of the circuit breaker or starting other automation elements.

Installation and application

Installing the auxiliary contact is simple and intuitive, so both installers and people with experience in electrical work can install it without problems. The ability to mount on circuit breakers from the AZ series allows you to adapt the protection system to the individual needs of the user. The contact finds application in:

• Signaling the status of the circuit breaker (e.g. alarm in case of tripping).
• Controlling other devices in the circuit (e.g. starting a fan after the circuit breaker trips).
• Expanding automation and electrical installation monitoring systems.
• Providing an additional level of safety by signaling failures or overloads.

Additionally, the lack of a residual current self-test means that this contact focuses exclusively on the auxiliary function, without introducing additional complications in the operation of the protection system. The ability to connect to two main contacts increases the flexibility of system configuration.
