The interrupting ratings climb to 75.6 kA at 240 V, 52.5 kA at 415 V, and still hold 11.9 kA at 690 V, so it handles high-fault scenarios on 480Y/277 V or 400 V industrial services without cascading upstream. The 75.6 kA at 240 V is the headline number, but the real-world decision point is the 52.5 kA at 415 V — that's the available fault current on a typical 400 V industrial service. If your transformer's impedance keeps the prospective short-circuit current under that, this breaker coordinates cleanly. Above that, it drops to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If your panel runs hot (enclosed, solar combiner, near a furnace), size the continuous load to the 70 °C figure, not the nameplate. The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.","metaTitle":"Siemens 3VA1150-3EF36-0CA0 SENTRON MCCB, 50 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1150-3EF36-0CA0 molded case circuit breaker, 50 A rated, 75.6 kA interrupting at 240 V, 3-pole, TM240 release, undervoltage release.
