Its 100 A continuous current (Iu) holds through 50 °C ambient; above that it derates to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C — so if the panel runs hot, size the breaker for the actual load at your ambient, not the nameplate 100 A. The interrupting ratings climb with voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V.
The 3VA2110-5HN36-0DC0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON panelboards or standalone DIN-rail adapters. The auxiliary trip coil (3VA9608-0BB25) is factory-installed; no field wiring of a separate shunt trip module needed. The undervoltage release is wired to a control circuit — it holds the breaker closed as long as voltage is present, and trips on dropout below the release threshold.
The 3VA2 frame is the successor to the older 3VL series, with a slimmer profile and the ETU electronic trip family. If you're replacing a 3VL breaker in an existing panel, check the mounting footprint and bus-bar spacing — the 3VA2 uses the same 105 mm width but the depth and terminal layout differ.
