Auxiliary switching is handled by two HQ auxiliary switches and an undervoltage release (UVR) is factory-fitted. The base switch platform is the 3VA11106MH320AA0. Power loss at full rated current is 27.5 W — relevant for enclosure thermal calculations if you are stacking multiple breakers in a confined panel. The 70 mm depth, 76.2 mm width, and 130 mm height fit the standard SENTRON 3VA mounting footprint — no panel rework if swapping from a same-frame 3VA. ## Current Derating and Thermal Reality At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. That is a 9 A drop across the full temperature span — predictable, linear derating. For a panel builder: if your enclosure ambient runs at 60 °C, you can still load this breaker to 96 A continuous without nuisance tripping. The 27.5 W power loss is the heat the breaker itself dumps into the enclosure at full load; factor that into your thermal budget alongside the derating curve.","metaTitle":"Siemens 3VA1110-6MH32-0CC0 SENTRON MCCB, 100 A, 3-Pole, 220","metaDescription":"Siemens 3VA1110-6MH32-0CC0 SENTRON molded case circuit breaker, 100 A rated at 40 °C, 3-pole, 220 kA breaking capacity at 240 V.
