The CS Electric Capacitor Duty Contactor is designed to safely switch capacitor banks in power factor correction systems. When a capacitor is turned on, a high inrush current can occur. This contactor uses built-in damping resistors and early-make auxiliary contacts to control that surge, protecting both the switch and the equipment. Once the capacitor is charged, the main contacts take over for normal operation. Compact, reliable, and engineered for heavy industrial use, it helps improve power quality while ensuring long service life.
