The Siemens SENTRON 3VA2110-0HN46-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous current (flat across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling).
At 690 V the rating is still 187 kA, so it handles 3-phase 690 V systems common in mining or marine installations.
Physical integration
Mounts in a standard panel or enclosure — dimensions are 181 mm height, 140 mm width, 86 mm depth. Front face carries IP40 protection, so it's suited for dry indoor panels where tools or fingers won't contact live parts. No undervoltage release or shunt trip on this order code; if you need remote tripping, specify a different variant.
Maximum power loss is 7.7 W — low enough that internal cabinet heating is negligible in most enclosures. The flat 100 A rating from 40 °C to 70 °C means no derating curve to calculate for warm panels; just ensure ambient doesn't exceed 70 °C operating (storage range is -40 °C to 80 °C).
