It is designed for isolation and switching of loads without overload or short-circuit protection. ## Shunt trip and auxiliary switching This unit ships with a factory-fitted shunt trip (STL) release, allowing remote tripping from a pushbutton, PLC output, or safety relay. The shunt trip coil draws power only during the trip event — no continuous hold current.","metaTitle":"Siemens 3VA1225-1AA42-0JC0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA42-0JC0 switch disconnector, 250 A rated continuous current, 4-pole, 690 V AC / 600 V DC, shunt trip, 2 aux switches HQ, IP40 front.
