Product description
MCB circuit breaker to protect the electrical installation against the effects of short circuits and overloads. It can also be used as a means of protection against electric shock - automatic shutdown in the event of a short-circuit with negligible impedance between the line conductor and the accessible conductive part or the protective conductor.
