NZMB1-AF50-NA protects systems
NZMB1-AF50-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-AF50-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.
