The 86 mm depth and 140 mm width fit standard SENTRON panel cutouts, so it swaps into existing 3VA footprints without re-drilling the backplate. ## Rating breakdown for selectivity and coordination The 250 A frame (Iu) holds full rating up to 50 °C; above that it derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 213 A at 70 °C. The ETU560 trip unit supports adjustable N-conductor protection from OFF to 20-100% of the phase current, which is useful for 4-wire systems where the neutral may carry harmonic loads. Front-face protection is IP40 — rated for indoor panel installation where no water jets or dust ingress are expected. The 4-pole design with 181 mm height and 140 mm width matches the standard SENTRON 3VA frame, so it drops into existing panel layouts that already use 3VA breakers.","metaTitle":"Siemens 3VA2225-6JQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2225-6JQ42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU560 trip unit, 242 kA at 240 V AC.
