Short Description

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 breakers operating handle restores the circuit.

Features

  • 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
  • Mounting with insta-wire
  • 4 to 1/0 AWG copper, 2 to 1/0 AWG aluminum wire
