Breaking capacity is 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. That 52.5 kA at 240 V gives solid headroom for high-fault service-entrance panels on 240 V delta or 120/240 V split-phase systems. At 415 V the 32 kA rating is typical for industrial MCCB duty on 400 V class supplies. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or direct-mount panel layouts. ## Overcurrent release and auxiliary release","metaTitle":"Siemens 3VA1020-2ED32-0DA0 SENTRON MCCB, 20 A, 3-Pole, 52.5","metaDescription":"Siemens 3VA1020-2ED32-0DA0 SENTRON molded case circuit breaker, 20 A rated, 3-pole, 52.5 kA breaking at 240 V.
