The 86 mm depth and 140 mm width match the standard SENTRON 3VA2 footprint, meaning it drops into the same panel cutout as the 3VA2116-5JP32-0AE0 (a 160 A frame) — same mounting pattern, same bus-bar spacing. You can swap the 100 A for the 160 A version later if the load grows, as long as the feeder and bus bars are sized for it. ## Integration notes The ETU350 trip unit is field-configurable — no need to pull the breaker for rating changes. ## Environmental range Rated for operation from -25 °C to 70 °C ambient, with no derating needed across that span — the 100 A rating holds at every temperature from 40 °C through 70 °C.","metaTitle":"Siemens SENTRON 3VA2110-5HN42-0AA0 MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2110-5HN42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU350 trip unit.
