Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Thermal derating is published across the full operating range: full 250 A up to 50 °C, then 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Rated insulation voltage is 800 V, and the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. ## Physical fit and integration Dimensions: 70 mm deep, 140 mm wide, 158 mm tall. Width of 140 mm for a 4-pole unit is typical for the frame size; check your DIN-rail or mounting-plate spacing before committing the panel layout. That means you get two form-C aux contacts for status feedback plus a dedicated trip alarm contact — enough for a basic motor control center or transfer scheme without adding an external accessory module. Maximum power loss is 59.5 W at rated current. Lifecycle stage is current — Siemens actively manufactures and supports this order code. No phase-out notice or last-time-buy window is indicated.","metaTitle":"Siemens 3VA1225-5GF42-0BH0 SENTRON MCCB, 250 A, 4-Pole, 70 m","metaDescription":"Siemens 3VA1225-5GF42-0BH0 SENTRON molded case circuit breaker, 250 A fixed rating, 4-pole, 187 kA at 240 V.
