Breaking capacity hits 75.6 kA at 240 V AC, dropping to 52.5 kA at 415 V and 11.9 kA at 690 V — the 240 V figure is the one to match against the available fault current at the service entrance. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel cutouts and busbar arrangements; the 3-pole width matches the 76.2 mm (3 in) footprint common across the series. Marked as current production — this is a standard-catalog SENTRON MCCB, not a phase-out or NRND line item.","metaTitle":"Siemens 3VA1150-3EF36-0AA0 SENTRON MCCB, 50A, 75.6kA IC","metaDescription":"Siemens 3VA1150-3EF36-0AA0 SENTRON 3-pole MCCB, 50A rated at 40°C, 75.6kA breaking at 240V.
