The 100 A holds flat from 40 °C up to 50 °C; above that it derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Breaking capacity steps with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel this lands between the 440 V and 500 V curves — the 32 kA at 440 V is the closest published figure, and the 11.9 kA at 500 V is conservative for 480 V. The basic switch assembly part is 3VA11103GF420AA0. The 3VA1110-3GF42-0AH0 measures 130 mm high, 101.6 mm wide, 70 mm deep. Four-pole width at 101.6 mm is standard for a 4-pole MCCB in this class — it occupies the same footprint as other SENTRON 3VA frame breakers.","metaTitle":"Siemens 3VA1110-3GF42-0AH0 SENTRON MCCB, 100 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1110-3GF42-0AH0 SENTRON 4-pole MCCB, 100 A, TM240 release.
