BL Type 240V Panelboard Breakers

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.

All circuit breakers perform the following functions:

  • SENSE when an over current occurs

  • MEASURE the amount of over current

  • ACT by tripping quickly enough to prevent damage to itself and associated conductors
