The interrupter also has a plunger and an armature, each slidably mounted at least partially within the electromagnetic coil. The armature can be magnetically driven by the coil against the plunger. A latch means is included for releasably holding the pair of movable contacts against the pair of stationary contacts. A fault detector can detect a fault in an electrical distribution system in order to actuate the electromagnetic coil.
