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).
