Dimensions are 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB footprint for DIN-rail or screw-mount panel integration. IP40 on the front face keeps out tool drops and dust during commissioning; the rear and sides are open for heat dissipation inside the enclosure. Power dissipation at full load is 28.1 W maximum. In a multi-breaker lineup, sum the losses to size the enclosure ventilation — a row of four of these adds over 112 W of heat inside the cabinet.","metaTitle":"Siemens 3VA1112-6EE42-0AA0 SENTRON MCCB, 125 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1112-6EE42-0AA0 molded case circuit breaker, 125 A continuous, 4-pole, TM220 release.
