The breaker is rated a full 50 A from 40 °C up to 50 °C ambient, then derates linearly to 45 A at 70 °C. That means in a crowded panel running at 55 °C you lose only 1 A — negligible for most designs. The 70 mm depth by 76.2 mm width footprint is standard for SENTRON 3VA fixed-thermal breakers; it snaps onto DIN rail or mounts directly to a backplate. The TM240 release is a thermal-magnetic trip with a 240 A frame — the 50 A continuous rating is set by the installed thermal element, not the frame size. That gives headroom: the same breaker platform can be ordered with higher amp ratings up to the 240 A frame limit.","metaTitle":"Siemens 3VA1150-6EF32-0AF0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0AF0 molded case circuit breaker, 3-pole, 50 A rated at 40 °C, TM240 release, 220 kA breaking at 240 V.
