The Siemens SENTRON 3VA1025-3ED32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 25 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. It's a current-production line protection breaker — no voltage trip or communication module on this variant.
Breaking capacity and thermal derating
Breaking capacity climbs to 75.6 kA at 240 V AC, drops to 52.5 kA at 415 V, and holds at 7.5 kA from 500 V up to the 690 V AC rated operating voltage. That's enough headroom for most 480 V industrial panels, but verify coordination with upstream devices at your available fault current. Thermal derating is mild: the breaker carries a full 25 A from 40 °C through 50 °C, then steps down to 24 A at 55–60 °C and 23 A at 65–70 °C.
Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint. The front face carries an IP40 rating, so it's fine in a clean indoor panel but not washdown-rated.
