That curve matters when the MCCB lives in a crowded, warm enclosure — the actual continuous current you can count on at 60 °C is 96 A, not the nameplate 100 A. Maximum power loss is 25 W. ## Mounting and Auxiliary Configuration The 3VA1010-4ED32-0AH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution panels and most DIN-rail or screw-mount enclosures.","metaTitle":"Siemens 3VA1010-4ED32-0AH0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1010-4ED32-0AH0 molded case circuit breaker, 100A rated, 3-pole, 121 kA interrupting at 240 VAC.
