How to use

Install the circuit breaker module according to local electrical codes and Schneider Electric mounting instructions. Ensure the main supply is isolated before wiring. Mount the module on the appropriate DIN-rail or panel slot, connect the incoming supply and outgoing load conductors to the designated terminals, and torque terminals to the manufacturer’s recommended settings. After installation, restore supply and verify correct operation by testing the protected circuit under controlled conditions.

Recommendations

Use this breaker in indoor environments where IP40 protection is sufficient; avoid locations with high humidity, dust ingress, or direct exposure to water. Match the breaker rating to cable and load specifications and adhere to applicable wiring regulations. For coordinated protection or special applications consult technical documentation or a qualified electrician.
