Breaking capacity hits 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault industrial feeds without cascading upstream. The 100 A rating holds steady up to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — a shallow curve that buys headroom in a warm cabinet. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep; the 76.2 mm width is a standard 3-pole MCCB footprint, so it drops into most panel-mount cutouts without re-drilling.","metaTitle":"Siemens SENTRON 3VA1110-4EF36-0BA0 MCCB, 100 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1110-4EF36-0BA0 molded case circuit breaker. 100 A continuous, 3-pole, TM240 release.
