20 Amp circuit breaker
Do not need fuses. In case of heavy overload (i.e.: short circuits), the circuit breaker disconnects instantaneously, for overloads up to 50% it maintains the contact for few seconds so, in case it is due to a chance event, it has time to return within the limits without interrupting the power supply. In case of short circuit, the switch cannot be reactivated until the problem is solved.
