It carries 100 A continuously at 40 °C ambient — no derating needed up to 50 °C, where it still holds 100 A — then tapers to 91 A at 70 °C. The interrupting capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC, which covers most industrial service-entrance and feeder applications without an upstream current-limiting fuse.
The overcurrent release is a TM220 — a fixed thermal-magnetic type with no electronic adjustment. The thermal element tracks the 100 A frame rating; the magnetic pickup is factory-set to a multiple of that rating. This is the standard choice for fixed-load feeders (pumps, conveyors, lighting panels) where you don't need adjustable trip curves. The 76.2 mm width (3 in) and 70 mm depth (2.76 in) let it drop into a standard SENTRON 3VA panelboard or DIN-rail adapter without forcing a layout change from the wider 3VA1 frame siblings.
Integration notes
Mounts in a DIN-rail enclosure or direct panel-mount via the 3VA accessory kit. IP40 on the front means splash protection from the panel face — keep the rear terminals inside an IP2X enclosure. No auxiliary contacts or trip-indicator flag on this variant — if remote status is needed, spec the -5ED32-0AA0 sibling instead.
