NZMB1-A50-NA Protects Systems |
NZMB1-A50-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-A50-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. |
