That UVR is a common spec for safety circuits where a drop in control power must open the main breaker. Thermal derating starts at 55 °C: the breaker holds 250 A flat through 50 °C, then steps down to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Maximum power loss is 50.5 W, which matters for enclosure heat rise calculations in a sealed panel. ## What the auxiliary release and switches add The two HQ auxiliary switches provide electrically isolated position feedback (open/closed) for PLC inputs or status indicators. Because both are factory-integrated into the 3VA2225-7HN32-0DC0 variant, there is no separate kit to order or install; the breaker arrives ready for control wiring to the UVR coil and the auxiliary terminals.","metaTitle":"Siemens 3VA2225-7HN32-0DC0 SENTRON MCCB, 250 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2225-7HN32-0DC0 molded case circuit breaker, 250 A continuous, 3-pole, 330 kA at 240 VAC.

Above 50 °C it derates: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.

At 480 VAC (common in North American 480Y/277 V systems) the rating falls between those two points — conservatively use the 187 kA figure at 500 VAC for coordination studies unless the manufacturer publishes a specific 480 V value."},{"question":"Does 3VA2225-7HN32-0DC0 include an undervoltage release?","answer":"Yes, it is factory-equipped with an undervoltage release (UVR) that trips the breaker on loss of control voltage.
