The 121 kA at 400 V class gives solid selectivity headroom for most European 400 V distribution panels without cascading upstream. It ships with a 4-auxiliary-switch HQ block fitted. ## Mounting and integration — panel checklist Mounts via the standard 3VA rear-panel screw pattern or onto SENTRON busbar adapters. The 138 mm width matches the 3-pole frame spacing; verify busbar center distances if retrofitting into an older panel. Spring-cage terminals on the load and line sides accept copper or aluminum conductors — strip length and torque values are on the nameplate. The 37.5 W heat dissipation at full load means adjacent breakers should be spaced per the manufacturer's derating guidelines in the installation manual; for a row of six at 250 A, forced ventilation may be needed above 50 °C ambient. ## Coordination and fault handling Line protection design means the trip curve is optimized for cable and busbar protection, not motor inrush. If you need motor branch-circuit protection, pair this with a contactor and overload relay upstream.","metaTitle":"SENTRON 3VA2325-5HN32-0AE0 3-pole MCCB, 250 A, 187 kA at 240","metaDescription":"Active-production SENTRON 3VA2325-5HN32-0AE0 molded case circuit breaker, 3-pole, 250 A continuous, 187 kA at 240 V.
