What this MCCB carries and where it lands
The Siemens SENTRON 3VA2225-8HL32-0BA0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C to 50 °C, with the ETU320 electronic trip unit handling the overcurrent protection curve. Breaking capacity lands at 440 kA at 240 V, 330 kA at 415/440 V, 242 kA at 500 V, and 50.4 kA at 690 V — numbers that tell you this breaker is built for high-fault utility infeed or large motor control center main service, not branch protection. The 86 mm depth and 105 mm width footprint fits standard SENTRON 3VA panel cutouts; the 181 mm height clears most enclosure gland plates without a riser.
Trip unit and release setup
The ETU320 electronic trip unit provides LI (long-time and instantaneous) protection — no ground-fault or voltage-trip function on this variant. An undervoltage release (UVR) is integrated as standard, part number 3VA9608-0BB11 for the release coil itself. No auxiliary contacts, no communication module, no phase-failure detection on this build — it's a clean line-protection breaker for applications where those extras aren't wired into the control scheme.
Thermal derating and endurance
Full 250 A rating holds through 50 °C ambient; above that it derates linearly to 213 A at 70 °C — the operating maximum. Mechanical endurance is rated at 20 000 operations latching; storage range from -40 °C to 80 °C covers most warehouse and site conditions. Maximum power loss at rated load is 50.5 W — factor that into enclosure ventilation if the panel is densely packed.
