The shunt trip (STL) auxiliary release allows remote tripping, useful for emergency-stop or interlock circuits. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard SENTRON 3VA footprint that fits existing distribution board cutouts.","metaTitle":"Siemens 3VA1112-3EF32-0KA0 SENTRON MCCB, 125A, 3-Pole, 75.6k","metaDescription":"Siemens SENTRON 3VA1112-3EF32-0KA0 molded case circuit breaker, 125A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
