K3-..K contactors are suitable for switching low-inductive, low-loss capacitors in capacitor banks without and with reactors (IEC 70 and 831, VDE 0560). The capacitor switching contactors are equipped with early-make contacts and damping resistors to reduce
the making current to < 70 x Ie. The capacitor switching contactors are protected against contact welding for a prospective making current of 200 x Ie. Fuse rating approx. 1.6 to 2.5 x Ie, type gL (gG).
