This breaker delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. For a 480 V panel (common in North American industrial distribution), the 415 V figure is the closest reference — 52.5 kA gives substantial headroom above a typical 25 kA or 42 kA available fault current. At 690 V the 10.5 kA rating still covers most European industrial grids. ## Thermal derating — don't size by the nameplate alone Above that it steps down: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If the breaker lives in a crowded panel or near heat-generating gear, use the 55 °C or 60 °C row for sizing — the 50 A nameplate is only valid up to 50 °C.","metaTitle":"Siemens 3VA1150-3EF36-0AB0 SENTRON MCCB, 50 A, TM240, 75.6 k","metaDescription":"Siemens 3VA1150-3EF36-0AB0 SENTRON molded case circuit breaker, 50 A rated, TM240 thermal-magnetic release, 75.6 kA at 240 V.
