Four switches with four levels of switching capacity

Four switches with four universal levels of switching capacity form a comprehensive range, from the competitively priced 25 kA for small sub-distribution boards, up to 150 kA switching capacity for complex high-power systems. The compact construction of the new small 160 A switch saves space as a main switch in machine control schemes, as an incomer in service distribution boards or as an outgoer in power distribution boards. Additional device levels are 300 A, the particularly compact 630 A, and the large 1600 A circuit-breaker.
