Overview

High-Performance Capacitor Switching Contactor

The CJ19(16) series is specifically designed for switching self-coupling low-voltage parallel capacitors within power factor compensation devices. These contactors effectively suppress high inrush currents during switching and control over-voltage when starting circuits, ensuring the longevity of your capacitor banks. Engineered for reliability, they are suitable for AC 50Hz or 60Hz systems with main circuit voltages up to 380V.
