INSTRUCTIONS FOR USING
Capacitor Switching Contactor
A capacitor switching contactor is a specialized device designed for switching capacitors in reactive power
compensation systems. This device combines a contactor with a starter specifi cally designed for AC-6b capacitor
applications, aiming to reduce the initial inrush current.
