Footprint is 130 mm high, 76.2 mm wide, 70 mm deep, so it fits standard 3-pole MCCB cutouts. ## Shunt trip and auxiliary options This variant ships without auxiliary contacts or undervoltage release, but it does include a shunt trip (STL) release — part number 3VA9688-0BL30 for the integrated auxiliary trip. The shunt trip is voltage-triggered, so wire it through a dry contact or safety relay.","metaTitle":"Siemens 3VA1112-3EF32-0HA0 SENTRON MCCB, 125 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1112-3EF32-0HA0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 3-pole, TM240 release, breaking capacity 75.6 kA at 240 V.
