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.

Rated to 72V DC, these can handle higher voltages than any other DC circuit breaker we offer. Use these circuit breakers in place of type ATC, AF, ATO, and 257 blade-style fuses to protect against overload and short circuits in low-voltage automotive and electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
DIN-rail mount holder is required (sold separately) to mount circuit breakers to DIN-rail.
