BCH MPH32-10 Motor Protection Circuit Breaker MPCB (6.3-10 A)
BCH MPH32-10 motor protection circuit breaker from the MPH series, relay range 6.3-10 A with magnetic trip at 130 A (13 x In). It combines thermal overload protection, phase failure protection and fuse-less short circuit protection in one compact unit with trip-free mechanism, temperature compensation and a rotary ON/OFF handle that moves to TRIP on short circuit or overload. Trip class 10, padlocking in OFF position, test function, 45mm frame.
