Positive Design Operation
They key for- positive operation is one assembly on one armature guide, all factory manufactured and 100 percent tested.
An extra set of line contacts, 3 poles, is part of the main armature guide. These are designed into the head of the contactor, along with a current limiting inductance to reduce the inrush. This is one assembly and hart of the contactor. When the contactor is turned ON, as the armature closes, the three extra poles are early make, before the main poles make to reduce the inrush current. Most important, these early make pales, then mechanically open as the armature picks up so the main poles only carry the continuous current.
