That 220 kA at 240 V places it in the high-fault category for North American 277/480 V panelboards where the line-to-neutral fault current can exceed 100 kA. At 690 V the 17 kA rating still covers most industrial motor-control-center fault levels. Thermal derating is minimal up to 50 °C — the breaker holds full 50 A. Above that it drops linearly: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a sealed, uncooled enclosure near other heat sources, plan for the 70 °C figure as the effective continuous rating. ## Panel integration The breaker occupies 101.6 mm width, 130 mm height, and 70 mm depth — a standard 4-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.","metaTitle":"Siemens 3VA1150-6GF42-0AA0 SENTRON MCCB, 50 A, 4-Pole, 220 k","metaDescription":"Siemens 3VA1150-6GF42-0AA0 SENTRON molded case circuit breaker, 50 A rated, 4-pole, TM240 release.
