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. 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.
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.
