The 3VA1025-2ED32-0AC0 is a Siemens SENTRON 3-pole molded case circuit breaker rated for 25 A continuous current at 40 °C, with a TM210 thermal-magnetic release — the '210' indicates the thermal element is fixed at 25 A and the magnetic pickup is at 10x In (250 A), so it's a line-protection breaker, not a motor-protection device. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V; that covers most industrial distribution panels up to 690 V line-to-line. Thermal derating is published: 25 A flat up to 50 °C, then 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C.
Panel integration and auxiliary wiring
Dimensions: 76.2 mm wide (roughly 3 inches, fits a standard 3-pole MCCB footprint on DIN rail or panel-mount), 130 mm tall, 70 mm deep. The TM210 release is non-adjustable for the thermal element (fixed at 25 A) but the magnetic trip is fixed at 10x In. If you need adjustable thermal or magnetic settings, look at the 3VA1 with an electronic release — this one is a straight thermal-magnetic fixed-trip breaker. The 15 000 mechanical endurance cycles (latching) is typical for this class; it's not a switching device for frequent on/load duty.
