That's a lot of fault-clearing headroom for a 250 A frame; it's sized for high-available-fault-current panels where a standard 65 kA MCCB wouldn't hold coordination. Thermal derating is published per degree: holds 250 A flat through 50 °C, then drops to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. ## Line protection build and auxiliary content This variant is designated line protection, meaning it's set up for feeder or main breaker duty, not motor branch circuit. The UVR drops the breaker on loss of control voltage, which is typical for emergency-stop or undervoltage protection schemes. Dimensions: 158 mm high, 140 mm wide, 70 mm deep — standard 4-pole MCCB footprint for Siemens SENTRON 3VA1 panelboards.","metaTitle":"Siemens 3VA1225-6GF42-0CC0 SENTRON MCCB, 250 A, 4-Pole, 220","metaDescription":"Siemens 3VA1225-6GF42-0CC0 SENTRON molded case circuit breaker, 250 A fixed, 4-pole, 220 kA at 240 V.
