The 100 A rating holds flat from 40 °C up to 50 °C; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C, so a panel running warm near the top of its operating range loses about 10 % of the continuous rating. At 240 V it interrupts 121 kA; at 415 V it handles 75.6 kA; at 440 V it drops to 52.5 kA; and at 690 V it still holds 11.9 kA. No undervoltage release, no shunt trip, no communication module — this is a straight line-protection breaker with no add-on accessories. ## Where it fits and how it mounts The 3VA1110-4EF32-0AF0 mounts on a DIN rail or directly to a backplate; the 70 mm depth, 76.2 mm width, and 130 mm height match the standard 3VA frame footprint.","metaTitle":"Siemens 3VA1110-4EF32-0AF0 SENTRON MCCB, 100 A, 3-Pole, Line","metaDescription":"Siemens 3VA1110-4EF32-0AF0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, line protection, TM240 release.
