The 3VA2110-5HN36-0AD0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current (Iu) — that's the load it carries without tripping under normal conditions. Breaking capacity hits 187 kA at 240 V and 121 kA at 415 V — that's the fault current it can safely interrupt without welding contacts or venting arc gas into the panel. At 690 V it still clears 4.25 kA, which covers most industrial line-to-line faults on a 690 V system. The 100 A rating holds flat from 40 °C up to 50 °C — no derating needed in a warm enclosure. At 70 °C it still carries 85 A, so you have headroom for a hot panel or a breaker mounted near other heat sources.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — fits standard MCCB cutouts in most distribution panels. The 86 mm depth means it clears shallow gland plates and leaves room for rear-mounted busbars. Comes with 3 auxiliary switches (HQ type) factory-installed — you get status feedback for PLC inputs or remote indication without adding a separate aux block.
