Its breaking capacity runs 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 — so it handles high-fault industrial mains without cascading upstream. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA panel footprints and mounts on a DIN rail or directly to a backplate. The 14.5 W heat dissipation means you should allow natural convection clearance in the enclosure.","metaTitle":"Siemens 3VA1020-3ED32-0CH0 SENTRON MCCB, 20A, 3-Pole, 75.6kA","metaDescription":"Siemens 3VA1020-3ED32-0CH0 SENTRON molded case circuit breaker. 20A, 3-pole, 75.6kA at 240V.

Both share the SENTRON 3VA family footprint (70 mm depth, 76.2 mm width, 130 mm height), so the panel cutout and DIN-rail mounting are the same — but verify the load rating and release wiring because the 3VA1110 carries a different current frame and may lack the UVR."},{"question":"What compliance documentation does this brand provide for 3VA1020-3ED32-0CH0?","answer":"Siemens SENTRON series MCCBs typically carry IEC 60947-2 certification, UL 489 listing, and CE marking.
