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. The breaker includes an undervoltage release (UVR) and two HQ auxiliary switches, so it can integrate into safety-related undervoltage trip schemes and provide remote status feedback without external add-on modules.
Integration and footprint
Dimensions are 158 mm high, 105 mm wide, and 70 mm deep — a standard SENTRON 3VA frame size that fits common panel cutouts and busbar systems. Rated insulation voltage is 800 V.
