The 250 A frame is fully rated across the 40–50 °C band with no derating, then steps down to 213 A at 70 °C — useful if the breaker lives near a heat source or in a poorly ventilated enclosure. ## Built-in diagnostics and auxiliary switching A trip indicator is standard — you get a visual flag that the breaker opened on a fault, not a manual switch-off. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm switch HQ, which gives you both a position-follow contact and a separate contact that only closes on a trip event. That pair lets a PLC or SCADA system distinguish between a commanded open and a protective trip without extra wiring.","metaTitle":"Siemens 3VA2225-5HN32-0AF0 SENTRON MCCB, 250 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2225-5HN32-0AF0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA breaking at 240 V.
