At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel footprints. The IP40 front rating means it's fine for indoor enclosures; no special sealing needed for the switchboard face. Above that it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. ## Built-in undervoltage release and auxiliary contacts It also carries 2 auxiliary switches HQ (high-qualified) for remote status indication. The integrated auxiliary trip uses order code 3VA9608-0BB25 for replacement. There is no communication module, no phase failure detection, and no ground fault monitoring on this variant. It's a straight line-protection breaker — no bells, no onboard metering. If you need those, you're looking at a different 3VA option.","metaTitle":"Siemens 3VA1150-3EF32-0DC0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1150-3EF32-0DC0 molded case circuit breaker, 50 A rated, 3-pole, 75.6 kA at 240 V.
