The shunt trip operates on 220-250 V DC or 208-277 V AC. Mechanical endurance is 15,000 operating cycles typical. The 3VA1112-1AA36-0KA0 measures 130 mm high, 76.2 mm wide (roughly 3 inches — three 1-inch pole spaces), and 70 mm deep. It uses front terminal connections for the main circuit, accepting lug-type conductors. An optional motor drive can be added for remote operation.","metaTitle":"Siemens 3VA1112-1AA36-0KA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens 3VA1112-1AA36-0KA0 SENTRON switch disconnector, 125 A rated current, 3-pole, shunt trip release 220-250 V DC / 208-277 V AC.

It shares the same frame size, dimensions, and shunt trip option, but it includes overload and short-circuit protection, while the 3VA1112-1AA36-0KA0 is a pure switch disconnector without protection.
