Breaking capacity reaches 53 kA at 240 V AC, stepping down to 32 kA at 415 V and 7.5 kA at 690 V, so the same breaker body covers a wide voltage range across the distribution board. The 70 mm depth and 101.6 mm width fit standard SENTRON 3VA panel cutouts — no adapter plate needed for a 4-pole frame in a 160 A frame size. ## Current derating and thermal budget Rated current holds at 25 A from 40 °C through 50 °C ambient, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. That 2 A drop across the upper range means the breaker can serve a 25 A continuous load in a warm enclosure as long as the internal temperature stays below 50 °C. Maximum power loss is 8.5 W — negligible for a single breaker but worth summing across a multi-breaker panel when sizing enclosure ventilation. ## Peer comparison — 3VA1020-3ED36-0AA0 The closest functional peer within the SENTRON 3VA family is the 3VA1020-3ED36-0AA0. Both are 4-pole MCCBs in the same frame size, but the 3VA1020-3ED36-0AA0 carries a 20 A rated current (vs. 25 A here) and uses a TM230 trip unit instead of the TM210. The 25 A version provides 5 A more headroom for the same panel cutout, so if the original BOM specified the 20 A breaker and the load margin is tight, this 25 A unit is a direct mechanical swap — same footprint, same terminal arrangement. The trip curve differs slightly (TM210 vs. TM230), so verify coordination with downstream devices if replacing an existing 20 A breaker.","metaTitle":"Siemens 3VA1025-2ED46-0AA0 SENTRON MCCB, 25 A, 4-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1025-2ED46-0AA0 molded case circuit breaker, 25 A rated current, 4-pole, TM210 thermal-magnetic trip, breaking capacity 53 kA at 240 V.
