Rated 160 A continuous at 40 °C, it holds that rating flat through 50 °C, then derates gradually to 150 A at 70 °C. That thermal curve matters: in a sealed panel with no forced cooling, you can count on the full 160 A up to 50 °C — a real advantage in warm enclosures. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V.
Built-in auxiliary switches and shunt trip — no add-on modules needed
That means you get remote status indication (open/closed/tripped) and remote trip capability without buying separate accessory packs or wiring into the handle mechanism. For a panel builder, that saves a DIN-rail slot and the labor of snapping on external aux blocks.
Panel fit — dimensions and wiring
Footprint is 130 mm high, 101.6 mm wide, 70 mm deep — roughly 5.1 x 4 x 2.8 inches. Width at 101.6 mm means it takes a standard 4-inch mounting space on the DIN rail or backplate.
