The 100 A rating holds flat from 40 °C to 50 °C, then derates gradually to 91 A at 70 °C, so a panel running at 45 °C gets the full 100 A. ## Fit and panel integration Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole MCCB that fits standard Siemens SENTRON mounting bases. Optional motor drive allows remote tripping or reset — useful for unattended switchgear. The 100 A frame with TM220 release is sized for feeder or large branch circuits in commercial and industrial distribution. At 415 V it still interrupts 52.5 kA, so it handles most 400 V distribution bus faults.","metaTitle":"Siemens 3VA1110-3FE42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1110-3FE42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, interrupting 75.6 kA at 240 V.
