Current rating holds flat at 100 A from 40 °C through 50 °C, then tapers to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Four auxiliary switches (HQ type) come built in. The 76.2 mm width is the standard 3-pole MCCB footprint — it drops into the same cutout as other SENTRON 3VA frames, so swapping a 3VA1010 or 3VA1110 variant means no re-drilling the backplate.","metaTitle":"Siemens 3VA1110-4EF32-0AE0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens 3VA1110-4EF32-0AE0 SENTRON molded case circuit breaker, 100A rated, 3-pole, TM240 release. 121 kA at 240 V.
