When it may not be suitable

How to use

To install the Legrand 417400, ensure that the main power supply to the MPX3 circuit breaker is disconnected. Align the auxiliary contact with the side of the circuit breaker housing as indicated in the installation manual. Snap the device into place until it is securely locked. Once mounted, connect the necessary control wiring to the terminals according to your circuit diagram. Verify the connection by testing the signaling function before restoring power to the main system.

What to consider before purchase

Verify compatibility with your specific MPX3 model
Ensure the control circuit voltage matches the contact ratings
Confirm available space on the side of the circuit breaker for mounting

Usage recommendations: Always perform a functional test of the auxiliary contact after installation to ensure that the signaling state correctly reflects the position of the circuit breaker. Ensure all wiring is tightened to the manufacturer's specified torque settings to prevent loose connections.
