The 76.2 mm width and 70 mm depth fit standard 3-pole MCCB panel slots; the 130 mm height clears most enclosure gutters. At 415 V it still manages 32 kA — enough for European 400 V systems with high transformer ratings. The 13.6 kA at 440 V and 7.5 kA at 690 V matter for industrial 690 V drives and genset feeds; if your available fault current at 690 V exceeds 7.5 kA, you need a current-limiting upstream device or a higher-rated frame. ## Thermal derating — don't lose headroom at elevated ambient The 20 A rating holds flat up to 50 °C ambient. Above that it derates: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. ## Auxiliary contacts and release options If you need those, the 3VA family supports them as field-installable accessories, but this specific unit leaves those slots empty. The IP40 front protection (finger-safe) is standard for panel-mounted breakers; the rest of the breaker is IP20 once installed.","metaTitle":"Siemens 3VA1020-2ED32-0AC0 SENTRON MCCB, 20 A, 3-pole, TM210","metaDescription":"Siemens SENTRON 3VA1020-2ED32-0AC0 molded case circuit breaker, 20 A rated, 52.5 kA at 240 V, TM210 release, in current production.

The difference is the continuous current rating: this unit is 20 A, while the 3VA1010 variant is 10 A. If the panel was designed for 10 A branch protection, dropping in a 20 A breaker may violate coordination or conductor sizing — verify the load and upstream protection before swapping."},{"question":"What compliance documentation does this brand provide for 3VA1020-2ED32-0AC0?","answer":"Siemens SENTRON breakers carry CE marking for European markets and are designed to IEC 60947-2.
