That's a high-interrupting-capacity (HIC) device — suitable for main or tie breakers in panels with high available fault current, not just branch feeders. ## Thermal derating — real-world current At 55 °C and 60 °C it derates to 31 A, and at 65 °C and 70 °C it's 30 A. That means in a warm panel — say 55 °C — you lose 1 A of headroom. If you're loading it near 32 A continuous in a hot enclosure, factor that 31 A limit into your design. ## Built-in auxiliary devices This MCCB ships with two factory-fitted auxiliary switches (HQ design) and an undervoltage release (UVR). No special adapter needed for a standard Siemens distribution board.","metaTitle":"Siemens 3VA1132-4EF32-0CC0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0CC0 molded case circuit breaker, 32 A rated, 3-pole, interrupting capacity 121 kA at 240 V.
