Front auxiliary contact 1NO + 1NC for MPX3 417403

Auxiliary contact for MPX3 circuit breakers – expanding functionality

This auxiliary contact, designed for MPX3 motor circuit breakers, allows for increased flexibility and adaptation of the installation to specific needs. Mounted on the front of the circuit breaker, it enables the addition of additional control or signaling circuits without the need to interfere with the main installation. This is particularly useful in applications requiring remote monitoring of the circuit breaker status or control of other devices.

Mounting and connections

The contact is mounted on the front of the MPX3 circuit breaker, ensuring quick and easy installation. It uses screw connections, guaranteeing a secure and durable connection of the wires. The design allows for top mounting, which facilitates access and convenience during installation and maintenance.

Characteristics and application

The contact has one normally open contact (1NO) and one normally closed contact (1NC), allowing for configuration of various control functions. The rated current of 3A at AC-15, 230V makes it suitable for controlling circuits with lower power consumption – e.g. contactor coils, signal lamps or alarm systems. The lack of fault signaling contacts means that its main task is to expand control capabilities, not to monitor the operating status of the circuit breaker. Thanks to this, it can be used in applications requiring precise process control or integration with automation systems.
