Full 250 A holds through 50 °C ambient. At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A. The maximum power loss is 48 W, which matters for enclosure heat rise calculations when grouping several breakers. ## Trip unit and auxiliary release configuration The ETU320 overcurrent release provides electronic trip curves for line protection — no ground-fault monitoring, no phase-failure detection, no communication module. The shunt trip (STL) is built in for remote tripping; the integrated auxiliary trip is order code 3VA9688-0BL33. No auxiliary contact version is fitted, and there is no undervoltage release. The supplied basic switch is 3VA2225-5HL32-0AA0. ## Environmental limits and endurance The latching endurance is rated at 20 000 operations — adequate for distribution duty where the breaker is not cycled daily.","metaTitle":"Siemens 3VA2225-5HL32-0KA0 SENTRON MCCB, 250 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2225-5HL32-0KA0 molded case circuit breaker, 250 A rated current, 3-pole, line protection with ETU320 release.
