Breaking capacity is 121 kA at 240 VAC and 75.6 kA at 415 VAC — numbers that put it well into high-fault-duty territory for commercial and light industrial mains. It is a straightforward, hard-wired breaker for a 50 A feeder where you need the interrupting rating and do not need the accessories. The front carries IP40 protection — fine for a dry indoor panel, not for washdown. Dimensions are 130 mm high, 50.8 mm wide (2 inches — standard 2-pole MCCB width), 70 mm deep. Power loss at rated load is 9.74 W, which matters for thermal budgeting in a dense enclosure. The 50.8 mm width (2 inches) matches the footprint of most 2-pole MCCBs in the SENTRON family, so it swaps into an existing cutout or busbar arrangement without re-drilling. IP40 on the front means the breaker face is protected against solid objects over 1 mm — standard for a closed cabinet.","metaTitle":"Siemens 3VA1150-4ED22-0AA0 SENTRON MCCB, 50 A, 2-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1150-4ED22-0AA0 molded case circuit breaker, 50 A rated, 2-pole, 121 kA breaking capacity at 240 VAC.
