The Siemens SENTRON 3VA1225-6EF32-0CC0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection, carrying a continuous current rating of 250 A across the 40 °C to 50 °C band without derating, then stepping down to 223 A at 70 °C. Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V, which makes it suitable for high-fault-current main feeders or large sub-distribution boards where fault levels exceed standard MCCB ratings.
