Footprint is 138 mm wide × 248 mm tall × 110 mm deep — a standard 3-pole MCCB envelope that fits existing SENTRON 3VA cutouts and busbar systems without re-drilling the backplate. The basic switch variant is 3VA2325-5MN32-0AA0; this order code adds the shunt trip and auxiliary switch block, so the depth clearance needs to accommodate the STL actuator — 110 mm is the installed depth with the aux block fitted. ## Specs That Matter for the BOM Line Operating temperature range is -25 °C to +70 °C, storage from -40 °C to +80 °C — the 70 °C operating ceiling matches the flat 250 A rating, so no derating needed even at the top of the band. Short-time delay adjustable from 4 s minimum to 17 s maximum — this is the I²t withstand time for selective coordination downstream; a 17 s delay lets downstream breakers clear before this unit trips, keeping the rest of the bus live.","metaTitle":"Siemens 3VA2325-5MN32-0KH0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0KH0 molded case circuit breaker, 250 A rated at 40-70°C, 187 kA SCCR at 240 V.
