At 440 V it still breaks 32 kA; at 690 V it holds 10.5 kA. At 55 °C it drops to 48 A, at 60 °C to 47 A, at 65 °C to 46 A, and at 70 °C to 45 A. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3-pole MCCB footprint for DIN-rail or screw-mount backpan. No auxiliary contact slot populated, so if you need a status feedback contact, you'll add one externally or order a variant with the aux pre-installed.","metaTitle":"Siemens 3VA1150-3EF32-0HA0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1150-3EF32-0HA0 molded case circuit breaker, 50 A rated, 3-pole, line protection, 75.6 kA at 240 V.
