Capacitor Contactor

Benedikt & Jäger is the industry leader in capacitor switching contactors. Pre-make contacts and resistors reduce current inrush during switching, thus providing less stress for both the contactor and the capacitor. They are suitable for both reactive and non-reactive capacitor banks, and do not create any performance losses as the resistors are switched out of the circuit during operation.

Specification: Contactors K3-..K are suitable for switching low-inductive and low loss capacitors in capacitor banks (IEC70 and 831, VDE 0560) without and with reactors.
Capacitor switching contactors are fitted with early make contacts and damping resistors, to reduce the value of make current <70 x Ie
.
Operating Conditions: Capacitor switching contactors are protected against contact welding for a prospective making current of 200 x Ie
