Series CSCN - Contactors designed for capacitor switching application

Energy management applications

With built-in resistance to switch three phase capacitor banks


“CSCN” contactors incorporate a front block with three early-make auxiliary contacts together with 6 quick discharge resistors (two per phase) through which the capacitors are switched to the network, reducing the current peak. Once the resistors have damped the current peak, the main contacts short-circuit the resistors, carrying the uninterrupted current. A few miliseconds later the early-make auxiliary contact closes to guarantee that all current flows through the main contacts.
