Auxiliary contact block 1NO 1NC NHI11-PKZ0 072896

Auxiliary contact block – expanding the functionality of circuit breakers

The NHI11-PKZ0 auxiliary contact block from Eaton is a reliable solution for expanding the functionality of circuit breakers, providing additional auxiliary contacts for signaling or control needs. Designed for side mounting, it offers flexibility in configuring electrical installations. It is an element dedicated primarily to residual current circuit breakers of the PKZ(M)0 series, but can be used wherever an increase in the number of auxiliary contacts is required.

Construction features and application

The construction of the contact block is based on screw connections, which guarantees secure and durable electrical connections. It has one normally closed contact (1NC) and one normally open contact (1NO), allowing for the implementation of various functions in the circuit. Side mounting facilitates installation and allows for optimal use of space in the switchboard. Thanks to this, installers can quickly and efficiently adapt the circuit breaker to the specific requirements of the application.

This block is ideal for applications where additional signaling of the circuit breaker status or remote control of auxiliary circuits is needed. It can be used in automation systems, lighting control, or industrial applications requiring device status monitoring. The rated operating current of 3.5A for AC-15 at 230V ensures reliable operation in typical control circuits. The absence of a holder simplifies installation and minimizes the risk of errors during installation.
