Maximum power loss is 21.7 W, so account for that heat when sizing the cabinet's thermal budget. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and distribution blocks without re-drilling the mounting plate.","metaTitle":"Siemens 3VA1180-4EF32-0CC0 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-4EF32-0CC0 molded case circuit breaker, 3-pole, 80 A rated at 40 °C, 121 kA breaking capacity at 240 V.
