How to use

Install the circuit breaker into a compatible DIN rail or panel cutout following applicable electrical codes and the system schematic. Ensure power is disconnected before making connections. Connect the line and load conductors to the terminals using correctly rated wiring and tightening torque. After installation, restore power and verify proper operation by checking that the breaker resets and trips under test conditions or simulated faults according to local testing procedures.

Recommendations

Verify compatibility with the existing distribution board and the required trip characteristics for the protected circuit. Use appropriate conductor cross-sections and torque settings during installation. Schedule periodic inspections to confirm terminals remain tight and the device operates correctly; replace the breaker if mechanical damage or inconsistent tripping behavior is observed.
