micro circuit breaker BB1-63-16A/2

The micro circuit breaker BB1-63-16A/2 pole,

1.  16A in the model number indicates the current rating of the circuit breaker. In this case, it is rated for a maximum current of 16 amperes. It means that the breaker is designed to trip or disconnect the circuit if the current exceeds 16A, protecting the electrical wiring and equipment.
2. : The 2 pole specification refers to the number of poles in the circuit breaker. In this case, it is a 2-pole breaker, which means it can simultaneously protect two separate electrical circuits. Each pole can independently interrupt the flow of current when a fault occurs.
