Cutler-Hammer Load-Center Circuit Breakers


1 Pole—Toggle-Switch Style	2 Poles—Toggle-Switch Style

Install these circuit breakers into Cutler-Hammer CH series breaker boxes. Because these circuit breakers are thermal-magnetic, they trip two different ways. They either trip when heat is generated slowly by consistent low-level overload current or quickly when the magnetic coil senses a high-current short circuit.

UL 489—They meet UL 489 requirements for branch circuit protection and are certified as current limiting, so they protect equipment by minimizing passing current during a short circuit.

Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
