The interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — covering most low-voltage fault-current scenarios across North American and IEC installations. The 3-pole frame with line-protection firmware (no ground-fault, no communication) keeps it a straightforward, high-SCCR choice for feeder or branch-circuit duty. For a critical-spare holding or a BOM freeze, this is a stable line item — no imminent PCN or LTB to track. The 3VA1150-3EF32-0JA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 3-pole footprint fits standard distribution board cutouts; verify the shunt trip wiring (3VA9688-0BL32 integrated auxiliary trip) before energizing — polarity on the STL coil matters. No auxiliary contact version is fitted, and there is no communication function or phase-failure detection — this is a pure line-protection breaker with a remote-trip shunt. The TM240 release is factory-set; field adjustment is via the front dial if the variant supports it (check the specific 3VA1 manual for the TM240 adjustment range).","metaTitle":"Siemens 3VA1150-3EF32-0JA0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1150-3EF32-0JA0 SENTRON molded case circuit breaker, 50 A rated continuous current, 3-pole, line protection version with TM240 release and shunt trip.
