Capacitor Contactor CJ19-4311, 20kVAR, 1NO+1NC, 220V — Reactive Power Compensation Switching
Capacitor Contactor CJ19-4311, 20kVAR, 1NO+1NC, 220V is a specialized contactor designed for switching capacitor banks in reactive power compensation systems. Featuring a normally open (NO) and a normally closed (NC) auxiliary contact, this 220V AC powered contactor mitigates inrush currents during capacitor switching, preventing contact damage and ensuring reliable operation. Its staged switching design extends the lifespan of the contactor and the connected capacitors, improving system efficiency and reducing maintenance.
