Auxiliary contact, 1 normally open + 1 normally closed Z-HK 248432

Auxiliary contact for circuit breakers – expanding the functionality of installations

The Z-HK auxiliary contact from Eaton is a reliable solution for expanding the functionality of residual current circuit breakers. It allows adding additional normally open and normally closed contacts, which is crucial in applications requiring circuit status signaling or remote control. Compact dimensions, only 0.5 module wide, allow easy integration with existing installations without taking up much space in the distribution board.

Versatility and operating parameters

This auxiliary contact, designed to operate at AC 230V, offers one normally open contact (1NO) and one normally closed contact (1NC). The rated switching current is 3A, making it suitable for applications with moderate load. The possibility of mounting with a residual current circuit breaker ensures compatibility with a wide range of Eaton devices. It allows connection to two main contacts with a maximum current of 8A.

Installation and application – for installers and users

The installation of the Z-HK auxiliary contact is simple and intuitive, which translates into time savings during installation. This means that both professional installers and people with basic electrical knowledge can easily install it. This contact is used in home automation systems, lighting control, alarm signaling and anywhere where additional control of electrical circuits is needed. Additional contacts allow the implementation of complex logical functions without the need for additional relays or controllers.
