That 75.6 kA figure at 240 V tells you this breaker can sit upstream of a high-fault panelboard without cascading; the 7.5 kA at 690 V is the ceiling for a 690 V line-side application. The TM210 overcurrent release is a thermal-magnetic fixed-trip — no electronic adjustment, no communication, no phase-failure detection. ## Derating and panel fit The 20 A rating holds flat from 40 °C through 50 °C; at 55 °C it drops to 19.2 A, at 60 °C to 18.8 A, at 65 °C to 18.4 A, and at 70 °C to 18 A. If the panel ambient inside the enclosure runs above 50 °C, that 2 A difference matters for a continuous load near the limit. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount SENTRON busbar systems.","metaTitle":"Siemens 3VA1020-3ED32-0HA0 SENTRON MCCB, 20A, 3-Pole, TM210","metaDescription":"Siemens 3VA1020-3ED32-0HA0 SENTRON 3-pole MCCB, rated 20 A continuous, 75.6 kA at 240 V.
