The Growcol micro circuit breaker BB1-63-63A/2 is a two-pole circuit breaker with a current rating of 63 amperes, designed to trip or open the circuit if the current exceeds 63A. BB1: This indicates the model or series of the circuit breaker. 63-63A: This indicates the current rating or capacity of the circuit breaker. In this case, it means the circuit breaker is rated for a maximum current of 63 amperes (A) and has a trip current of 63 amperes as well. This means that the circuit breaker will trip or open the circuit if the current exceeds 63A. /2: Two-pole circuit breaker interrupts the current flow in two conductors simultaneously.
