Front protection is IP40, so this mounts in a panel enclosure — not exposed to washdown. The 130 mm height, 76.2 mm width, and 70 mm depth fit standard SENTRON 3VA panel cutouts and busbar systems. This breaker's short-circuit ratings are specified at four voltage levels: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. For a 480 V panel fed from a transformer with 65 kA available fault current, the 415 V rating (154 kA) gives ample headroom for full selectivity downstream. The 690 V rating (17 kA) is lower — verify coordination if this breaker is used on a 600 V delta system. The TM240 release is thermal-magnetic — fixed thermal pickup at 50 A, magnetic trip factory-set. No electronic adjustments or communication functions on this variant. The 50 A rating holds at ambient up to 50 °C; above that, derate to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a warm panel (55 °C internal), plan for 48 A continuous load max. The 3VA1150-6EF32-0CC0 is a current product. No direct second-source exists; the closest functional peer is the 3VA1112-5EF32-0CA0, but verify coordination before substituting. ## Panel Integration The 76.2 mm width (3-pole) matches standard SENTRON busbar and DIN-rail adapter spacing. Depth of 70 mm leaves clearance for rear-connected busbars. The undervoltage release coil is wired separately — confirm control voltage matches the UVR rating.","metaTitle":"Siemens 3VA1150-6EF32-0CC0 SENTRON MCCB, 50 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0CC0 molded case circuit breaker, 50 A rated, 3-pole, TM240 release, 220 kA at 240 V.
