Mounting is fixed to a backplate via screw terminals, with front-facing connections on both line and load sides — a clean layout for panel builders who want all terminations accessible from the front. The 75 mm width and 60 mm depth fit standard distribution board cutouts; the 25 mm connection pitch matches common busbar and cable lug spacing.
Pollution degree 3 (IEC 60664-1) and overvoltage category III suit fixed installations with mains transients. The 440 V insulation voltage provides headroom above the 415 V operational voltage.
Integration and compliance notes
The IP20 finger-safe terminals protect against accidental contact during maintenance, but the breaker is not sealed against dust or moisture; install in a clean, dry enclosure. At altitudes above 2000 m, derate per the manufacturer's curve up to 5000 m. Power dissipation is 18.7 W per pole at rated current — account for that in the panel's thermal budget to avoid nuisance tripping from ambient heat buildup.
