For a 480 V panel, the 75.6 kA rating at 440 V is the closest published figure; the 30 kA at 500 V covers 480 V systems with margin. The 17 kA at 690 V suits European 690 V motor control centers. ## Thermal derating and continuous current Derating starts at 55 °C: 243 A, then 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Maximum power loss is 57 W. The 4-pole frame fits a 140 mm wide × 158 mm high × 70 mm deep footprint — standard for SENTRON 3VA plug-in or fixed mounting. The basic switch supplied is 3VA12256EF420AA0. Trip indicator is not present; voltage trigger is present. This variant is configured for line protection with the shunt trip for remote opening — typical for emergency-off or interlocking circuits.","metaTitle":"Siemens 3VA1225-6EF42-0HC0 SENTRON MCCB, 250 A, 4-Pole, 220","metaDescription":"Siemens 3VA1225-6EF42-0HC0 SENTRON molded case circuit breaker, 250 A at 40 °C, 4-pole, breaking capacity 220 kA at 240 V.
