Derating starts at 55 °C (19.2 A), dropping to 18 A at 70 °C. If the MCCB sits in a crowded enclosure near other heat sources, use the 55 °C figure for your load calculation — the breaker will trip earlier than the 20 A label suggests. That 70 mm depth is the panel-space constraint for gland plates or backpanel clearance; the 76.2 mm width (roughly 3 inches) means it occupies three 25 mm DIN module positions. ## What the TM210 release and UVR mean for selectivity This is a standard line-protection MCCB, not a motor-protection breaker with adjustable trip classes. The undervoltage release (UVR) trips the breaker when its coil loses voltage; it's wired to an external control signal or safety relay. If you need auxiliary contacts for status feedback, note this order code ships without them (auxiliary contact version: without). The integrated auxiliary trip accessory is order code 3VA9608-0BB24 if you add it later.","metaTitle":"Siemens 3VA1020-2ED32-0CA0 SENTRON MCCB, 20 A, 52.5 kA at 24","metaDescription":"Siemens 3VA1020-2ED32-0CA0 SENTRON molded case circuit breaker, 20 A rated current, 52.5 kA breaking capacity at 240 V.
