It's rated 40 A continuous, with 100 mA sensitivity, Type AC (sinusoidal AC residual currents only). That 100 mA threshold makes it a good fit for general-purpose circuits where a higher trip level avoids nuisance tripping from normal leakage, like on distribution boards feeding multiple loads. Breaking capacity is 1500 A (Idm and Im both 1500 A), and insulation voltage is 500 V AC.
The 36 mm width (4 module spaces) fits neatly into a modular enclosure or distribution board. Terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible wire; strip length is 14 mm. IP20 on the device body, IP40 inside a modular enclosure — fine for dry indoor panels, not for washdown areas.
