DIN-Rail Mount AC Branch Circuit Breakers
1 Pole Circuit Breaker
2 Pole Circuit Breaker
3 Pole Circuit Breaker
Use these circuit breakers upstream from small transformers, lighting, and control circuits. They meet UL 489 requirements for branch circuit protection. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit. Mount directly to DIN rail.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Alarm (sold separately) sends an audible signal when the breaker is tripped.
