Siemens SpeedFax™ B215M Molded Case Circuit Breaker With Insta-Wire, 120/240 VAC, 15 A, 10 kA Interrupt, 2 Poles, Thermal Magnetic Trip
Circuit breakers provide a manual means of energizing and de-energizing a circuit. In addition, circuit breakers provide automatic over current protection of a circuit. A circuit breaker allows a circuit to be reactivated quickly after a short circuit or overload is cleared. Unlike fuses, which must be replaced when they open, a simple flip of the breaker's operating handle restores the circuit.
