Breaking capacity hits 242 kA at 240 V and 187 kA at 415 V — numbers that tell you this breaker is sized for high-fault panels where a standard MCCB would cascade upstream. At 690 V it still holds 4.5 kA, which covers most industrial motor circuits on that voltage class. Footprint is 140 mm wide, 181 mm tall, 107 mm deep — fits standard SENTRON 3VA panel cutouts. IP40 on the front means it lives in a clean enclosure; no washdown exposure. The auxiliary contact block ships as 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch HQ, so you get status feedback without adding a separate module. Communication function is onboard, which for the ETU860 means you can pull trip data and current readings over the bus — saves climbing the panel for a visual check. Thermal derating is published per 5 °C steps from 40 °C: holds 250 A up to 50 °C, then drops to 240.625 A at 55 °C, 231.25 A at 60 °C, 221.875 A at 65 °C, and 212.5 A at 70 °C. If your panel ambient runs above 50 °C, size the breaker for the actual enclosure temperature — the 250 A nameplate is only good in a 50 °C or cooler cabinet.","metaTitle":"Siemens 3VA2225-6KQ42-0GL0 SENTRON MCCB, 250 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2225-6KQ42-0GL0 molded case circuit breaker, 250 A, 4-pole, line protection, ETU860 trip unit.
