Changeover switches on-load, are available from 125A to 200A and from 2000A up to 3150A in 3P – 3P+N. Long electrical and mechanical life even under extreme conditions (tropic and polar), as well as the polluted environment of any industrial process. Protection against accidental over voltages in equipments connected between phase and neutral (our standard 3P+N) whit advanced switched neutral pole (early make – late break).
