The series’ current-limiting design provides fast short circuit
interruption, within one half cycle of the fault, which reduces
circuit-damaging let-through energy. WMZT circuit breakers are
available with C and D curve thermal magnetic overcurrent protection
characteristics. C-curve devices are suitable for applications where
medium levels of inrush current are expected. D-curve devices provide
protection from nuisance tripping where high levels of inrush current
are expected. The series is also suitable for reverse-feed
applications. DIN-rail mountable. Features a trip-free design so the
breaker cannot be defeated by holding the handle in the “ON” position.
