The Siemens 3VA1025-3ED32-0JA0 is a SENTRON molded case circuit breaker (MCCB) rated for 25 A continuous current across a 40 °C to 50 °C ambient range, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. Three poles, line protection version — no auxiliary contacts, no undervoltage release, no communication module. The 75.6 kA breaking capacity at 240 V drops to 52.5 kA at 415 V and 32 kA at 440 V; at 690 V it still clears 7.5 kA. That spread tells you this breaker is sized for 480 V or 600 V class distribution panels where the available fault current is known and the TM210 curve matches the downstream load.
Panel integration and footprint
Width 76.2 mm, height 130 mm, depth 70 mm — three-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and busbar systems. No auxiliary contacts means no extra wiring space needed alongside. The shunt trip adds a pair of control wires; verify polarity on the release coil if your panel uses DC control.
