Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — enough to handle high-fault industrial distribution panels without cascading upstream. Full 25 A holds from 40 °C through 50 °C; at 55 °C it derates to 24 A, and at 70 °C it drops to 23 A. That means a 40 °C panel ambient keeps the full rating, but a hot control room near a kiln or furnace costs you 1–2 A. Maximum power loss is 8.5 W — negligible for panel heat budget, but worth noting if you pack twenty of these in a sealed cabinet. Footprint is 101.6 mm wide, 130 mm tall, 70 mm deep — a standard 4-pole MCCB envelope that fits most DIN-rail or panel-mount backplates without re-drilling. The TM210 release is fixed, no communication module, no undervoltage release — a straightforward thermal-magnetic breaker for basic feeder protection.","metaTitle":"Siemens 3VA1025-3ED46-0AA0 SENTRON MCCB, 25A, 4-Pole, 75.6kA","metaDescription":"Siemens 3VA1025-3ED46-0AA0 SENTRON molded case circuit breaker, 25A rated at 40°C, 4-pole, TM210 trip unit, 75.6kA breaking at 240V.
