At 690 V it still clears 6.3 kA, enough for 690 V drives or transformer secondaries. Two auxiliary switches plus a separate trip-alarm switch (HQ) give you status feedback for the SCADA or panel indication. ## Temperature derating and real-world current Above that, the ETU350 derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. For a critical spare, order one now and rack it before the existing breaker ages out. The 20,000 mechanical endurance cycles mean it's built for years of service in a typical industrial panel, but having a spare in the cabinet means no sleep lost if the primary fails. ## What's included and what's not The breaker ships with the ETU350 trip unit installed and the shunt trip (STL) fitted. It also includes the basic switch (order code 3VA2225-7HN32-0AA0) and the integrated auxiliary trip module (3VA9688-0BL30). It mounts directly onto the panel backplate or onto a DIN rail adapter (sold separately). The 86 mm depth includes the handle and terminals, so plan for at least 100 mm clearance behind the door.","metaTitle":"Siemens 3VA2225-7HN32-0HH0 SENTRON MCCB, 250A, 3-Pole, ETU35","metaDescription":"Siemens 3VA2225-7HN32-0HH0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU350 electronic trip unit, line protection.
