The breaking capacity numbers tell the real story here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. That's high-interrupting capacity for a 250 A frame — it handles fault currents that would vaporize a standard MCCB, so it's sized for large transformer secondaries or high-fault industrial distribution. Physically it measures 248 mm high by 138 mm wide by 110 mm deep — a standard 3VA2 frame footprint that drops into the same panel cutout as other 3VA2 breakers. The depth is 110 mm, so verify gland-plate clearance if the panel is shallow. ## Thermal derating and trip unit Rated 250 A at 40 °C, 45 °C, and 50 °C — no derating needed up to 50 °C. Above that it steps down: 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, 225 A at 70 °C. The ETU350 electronic trip unit handles the overcurrent protection curves. The shunt trip is the 3VA9688-0BL33 integrated auxiliary trip.","metaTitle":"Siemens 3VA2325-5HN32-0KA0 SENTRON MCCB, 250A, 187kA","metaDescription":"Siemens 3VA2325-5HN32-0KA0 SENTRON molded case circuit breaker, 250A rated continuous current, 187kA breaking at 240V. 3-pole line protection with ETU350 release and shunt trip.
