Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — that puts it in the high-interrupting class for industrial distribution where fault currents can hit 150 kA near a transformer secondary. ## Mounting and panel fit — dimensions and IP rating The 3VA1150-6MH32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or screw-mounted panel layouts without re-drilling. Continuous current holds 50 A up to 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.","metaTitle":"Siemens 3VA1150-6MH32-0AA0 MCCB, 50 A, 220 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1150-6MH32-0AA0 molded case circuit breaker, 50 A rated, 220 kA breaking at 240 V, TM120M release, IP40 front.
