It is designed for load-break isolation, not for overload or short-circuit protection — the description explicitly states 'without overload protection w/o short-circuit protection'. There are no auxiliary contacts (0 CO contacts) and no communication function. The main circuit connects via busbar connection at the front terminals. Rated continuous current Iu of 250 A is the maximum current the switch can carry continuously without exceeding its thermal limits. The 3-pole switch handles three-phase AC circuits up to 690 V AC 50/60 Hz, or DC circuits up to 500 V. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The width is the critical panel-space dimension — at 105 mm it takes up about 6 standard DIN-rail module widths (assuming 17.5 mm per module). The depth of 70 mm means it will fit most standard distribution boards, but check the door clearance if the panel has a shallow back box. This is a disconnect for isolation and infrequent load-break, not a contactor for cyclic duty. The wide storage range is useful for spares kept in unheated warehouses.","metaTitle":"Siemens 3VA1225-1AA32-0BA0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0BA0 switch disconnector, 250 A rated continuous current, 3-pole, 690 V AC / 500 V DC.
