Connection to the main circuit is via busbar on front terminals. The 3VA1225-1AA32-0KA0 occupies a 105 mm wide, 70 mm deep, 158 mm high footprint on the panel backplate. It is designed for busbar connection at the front terminals, which suits distribution blocks or panel-internal bus runs. No auxiliary contacts are fitted (0 CO contacts), and no undervoltage release is present; the only integrated release is the shunt trip.","metaTitle":"Siemens SENTRON 3VA1225-1AA32-0KA0 Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0KA0 switch disconnector, IEC frame 250, 3-pole, 250 A rated continuous current, shunt trip STL 220-250 V DC / 208-277 V AC.
