Auxiliary contact block 1NO 2NC NHI12-PKZ0 072895

Auxiliary contact block – expanding the functionality of EATON circuit breakers

This NHI12-PKZ0 auxiliary contact block, with catalog number 072895, is a key element for expanding the functionality of EATON PKZ(M)0 series circuit breakers. It allows adding additional signaling and control contacts to the existing installation, which translates into greater flexibility and control over the circuit. It is mounted on the side of the circuit breaker, which ensures convenient installation and minimizes space usage.

Characteristics and application

The NHI12-PKZ0 block is equipped with one normally closed contact (1NC) and two normally open contacts (2NO), allowing for the implementation of various signaling and control functions. The rated current of 3.5A at AC-15 230V makes it suitable for use in control circuits with lower current consumption. Screw connection ensures a secure and durable connection of wires.

• Status signaling: The contacts can be used to signal the status of the circuit breaker – on, off, or alarm.
• Control of auxiliary circuits: Allow controlling other devices in the circuit, e.g. signal lamps, contactors or relays.
• Expansion of automation systems: Allow integration of the circuit breaker with more complex automation and control systems.
• Mounting: Side and top mounting method facilitates installation in various configurations.

Advantages for the installer and end user

This contact block is not only additional functions, but also benefits for both parties:

• Versatility: Compatible with EATON PKZ(M)0 series circuit breakers – one element fits many applications.
• Simple installation: Easy side mounting saves time during installation.
• Flexibility: Possibility of configuring contacts according to the needs of a specific application.
• Reliability: High quality of workmanship guarantees long-lasting and trouble-free operation.
• Safety: Provides additional possibilities for monitoring the circuit status, increasing the safety of the installation.
• Cooperation with other devices: Easy integration with other elements of the control and automation system.
