AC Capacitor Switching Contactor
This AC contactor is designed for electric power systems to make and break self-coupling low-voltage parallel capacitors. It effectively reduces the impulse of switching rush current to the capacitor and controls the over-voltage when starting the circuit.

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.
