Breaking capacity is the headline spec here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. That 220 kA figure at 240 V gives you serious fault-current headroom for high-capacity transformer secondaries or large motor-control-center feeds. The 17 kA at 690 V still covers most industrial 690 V distribution. That makes it a straightforward choice for standard feeder protection where you don't need the selectivity flexibility of an electronic trip unit. The 3VA1150-6EF36-0AE0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole frame that fits standard Siemens SENTRON mounting accessories and busbar systems. The 70 mm depth means it projects less than many competing MCCBs, which helps when you're routing cables behind a backplate. The 3VA1150-6EF36-0AE0 is a current-production SENTRON MCCB.","metaTitle":"Siemens 3VA1150-6EF36-0AE0 SENTRON MCCB, 50 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1150-6EF36-0AE0 SENTRON molded case circuit breaker. 50 A rated, 3-pole, TM240 release.
