LV K3-K type
Contactors K3-..K are suitable for switching low-inductive and low loss capacitors in capacitor banks (IEC 70 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 making current < 70 x Ie
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).
