Auxiliary contact 1 NO+1 NC Z-LHK 248440

Auxiliary contact for expanding the functionality of circuit breakers

The Z-LHK auxiliary contact from Eaton is a reliable solution for expanding the functionality of circuit breakers, providing additional auxiliary contacts – one normally open (NO) and one normally closed (NC). Compact dimensions (0.5 module width) allow for easy integration with existing installations, and universal mounting makes it compatible with a wide range of devices.

Functionality and application

This auxiliary contact is designed for mounting with universal circuit breakers, enabling the implementation of additional signaling or control functions. A rated switching current of 6A and a maximum current of the main contacts up to 8A guarantee safe and efficient operation in various applications. Thanks to the rated voltage of 230V, this contact works perfectly in AC circuits.

• Functionality expansion: Adds one normally open (NO) and one normally closed (NC) contact to the existing circuit breaker.
• Status signaling: Allows connection of optical or acoustic signaling devices informing about the circuit status.
• Circuit control: Enables remote control of other devices based on the state of the circuit breaker.
• Compact dimensions: Occupies only 0.5 module width, making it easy to install in tight spaces.
• Universality: Compatible with various types of Eaton universal circuit breakers.

Characteristics and mounting

The Z-LHK auxiliary contact is characterized by a solid construction and high quality workmanship, ensuring long-lasting and trouble-free operation. Installation is simple and intuitive, and thanks to its small size, it does not significantly increase the overall size of the installation. The rated inrush current of 6A ensures proper cooperation with various loads, and the ability to handle up to 2 main contacts increases configuration flexibility. Remember to match the parameters of the auxiliary contact to the specifications of the specific circuit breaker and load.
