That 17 kA floor at 690 V still covers most industrial motor branch circuits. The thermal derating is mild — 50 A holds from 40 °C to 50 °C, then steps down to 45 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard MCCB footprint for a 3-pole frame. The shunt trip release (STL) allows remote tripping from an emergency-stop or safety circuit. The basic switch is order code 3VA11506EF320AA0.","metaTitle":"Siemens 3VA1150-6EF32-0HA0 SENTRON MCCB, 50A, 220kA at 240V","metaDescription":"Siemens 3VA1150-6EF32-0HA0 SENTRON molded case circuit breaker, 50A, 3-pole, 220kA interrupting at 240V.
