LV CC type

CC capacitor contactors are suitable for switching low-inductive and low-loss capacitors in capacitor banks, without and with reactors. CC capacitor contactors are designed to meet capacitor duty application. Contactors are fitted with a block of three early make auxiliary contacts in series with six damping resistors - 2 per phase. These auxiliary contacts limit peak current in the first stage of switching. Subsequently, the nominal current is transferred through main contacts which are switched in the next stage and the auxiliary contacts are switched-oof at the same time.

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).
