Interrupting capacity reaches 53 kA at 240 V, 32 kA at 415 V, 14 kA at 440 V, and 8 kA at 500 V — covering most low-voltage distribution panels and motor branch circuits. The breaker holds 20 A continuously from 40 °C through 55 °C, then derates to 19 A at 60–65 °C and 18 A at 70 °C — useful for panels with elevated internal ambient temperatures. Maximum power loss is 12 W, which factors into enclosure thermal calculations when grouping multiple breakers. Dimensions are 70 mm depth, 76.2 mm width, and 130 mm height — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without special adapters.","metaTitle":"Siemens 3VM1020-2ED32-0AA0 SENTRON MCCB, 3-Pole, 20 A, 53 kA","metaDescription":"Siemens SENTRON 3VM1020-2ED32-0AA0 molded case circuit breaker, 3-pole, 20 A rated, 53 kA interrupting at 240 V.
