Thermal derating is mild up to 50 °C — still 250 A — then drops to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. The 4-pole design covers three-phase plus neutral, common for main disconnects or feeder breakers in North American and European distribution panels. That covers most indoor and sheltered outdoor enclosures.","metaTitle":"SENTRON 3VA1225-6GF42-0DB0 MCCB, 250 A, 4-Pole, 220 kA at 24","metaDescription":"SENTRON 3VA1225-6GF42-0DB0 molded case circuit breaker, 250 A, 4-pole, interrupting capacity 220 kA at 240 V.
