That thermal curve matters in a packed panel; if you're stacking breakers in a warm cabinet, the 20 A rating is good up to 50 °C ambient without a second thought. ## Interrupting capacity across voltage classes This MCCB delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — numbers that cover most industrial distribution panels from 240 V single-phase up through 690 V three-phase. At 690 V the 7.5 kA rating still handles downstream faults in a wind or solar combiner application. ## TM210 release and shunt trip — what's built in That keeps the BOM simple: no programming, no auxiliary power needed for the trip unit. A shunt trip (STL) is integrated as the auxiliary release, part of the order code, so you can trigger a remote trip from an E-stop or PLC output without adding an external module. The integrated auxiliary trip accessory is order code 3VA9688-0BL30 if you need to add a separate signal contact later. ## Physical fit — DIN-rail and panel dimensions Width is 76.2 mm — that's a standard 4-module (4 x 18 mm) footprint on a DIN rail, so it occupies four TE slots in an enclosure. Depth is 70 mm, height 130 mm.","metaTitle":"Siemens 3VA1020-2ED32-0HA0 SENTRON MCCB, 20A, 52.5kA at 240V","metaDescription":"Siemens SENTRON 3VA1020-2ED32-0HA0 molded case circuit breaker, 3-pole, 20A rated, 52.5kA interrupting at 240V.
