Applying Capacitor Contactors
Capacitor contactors are used when switching a single step or multi step capacitor or condenser bank. They are required due to the very high inrush current (up to 60 x In) caused by energizing a capacitor. The LS Electric capacitor contactor units mount directly to the applied contactor. They consists of a dampening resistor which absorbs the ...
