For a 100 A frame, those are high-interrupting ratings — it is sized for installations with high available fault current, not a low-fault residential panel. No separate undervoltage module to buy and mount. At 55 °C it steps down to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. For a panel that runs hot, the 70 °C figure (91 A) is the one to use for sizing. The 70 mm depth fits a standard panel with room for wiring gutters. Maximum power loss is 27.5 W. That is the heat the breaker dumps into the enclosure at full rated current — relevant for thermal calculations in a sealed or high-density panel.","metaTitle":"Siemens 3VA1110-4EF32-0DA0 SENTRON MCCB, 100 A, 3-Pole, 70 m","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0DA0 molded case circuit breaker, 100 A at 40 °C, 3-pole, 121 kA breaking at 240 V.
