NZMB1-A40-NA Protects Systems

NZMB1-A40-NA circuit breakers protect entire systems on all levels, from the main distribution board right up to the loads. As the incoming circuit-breaker, the NZMB1-A40-NA will of course also provide secondary side overload protection for the transformer. A variant with modified short-circuit releases also enables a power network with time selectivity.
