Rated current holds at 50 A from 40 °C up to 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Breaking capacity varies with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. For a 480 V system, the 75.6 kA figure governs the SCCR rating of the downstream panel. The breaker occupies a 76.2 mm wide (3 in) footprint on the DIN rail or mounting plate, with a depth of 70 mm (2.76 in) and height of 130 mm (5.12 in). It ships with two auxiliary switches (HQ design) pre-installed for status feedback to the PLC or annunciator.","metaTitle":"SENTRON 3VA1150-5EF36-0AC0 MCCB, 50 A, 3-Pole, TM240","metaDescription":"SENTRON 3VA1150-5EF36-0AC0 molded case circuit breaker, 50 A at 40 °C, 3-pole, TM240 release, 187 kA at 240 V.
