This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That spread tells you where it has headroom for high-fault installations and where it's limited — at 690 V the 7.5 kA rating means it's not for high-fault 690 V feeders unless the available fault current is well under that. ## Thermal derating curve Rated 100 A from 40 °C through 50 °C, then it starts to step down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The 3VA1010-3ED42-0CH0 measures 70 mm deep, 101.6 mm wide, and 130 mm high — a standard 4-pole MCCB footprint for DIN-rail or panel-mount integration. The 101.6 mm width (4 inches) matches the typical 4-pole slot in a SENTRON distribution panel.","metaTitle":"Siemens 3VA1010-3ED42-0CH0 SENTRON MCCB, 100 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1010-3ED42-0CH0 molded case circuit breaker, 100 A rated at 40 °C, 4-pole, 75.6 kA breaking at 240 V.
