Panel integration and fit
It occupies 9 module pitches (81 mm wide, 137 mm high, 80 mm deep) and mounts on a backplate in horizontal or vertical orientation. Front-facing connections accept compression lugs or busbars, with a 35 mm connection pitch (27 mm without spreaders). The IP40 enclosure and IK07 impact rating suit it for distribution panels in controlled indoor environments — think electrical rooms, not washdown zones.
The utilisation category is A (no intentional short-time delay), so it trips instantaneously on magnetic pickup — fine for distribution, not for motor-start coordination where delayed trips are needed.
The overvoltage category is III — equipment fixed in the installation, fed from the mains distribution level. Operating altitude is 2000 m without derating, 5000 m with derating. Relative humidity range is 0 to 95 %.
Durability and dissipation
Mechanical durability is 20,000 cycles; electrical durability varies with load: 20,000 cycles at 440 V at In/2, 10,000 cycles at 440 V at In, 10,000 cycles at 690 V at In/2, and 5,000 cycles at 690 V at In. Power dissipation is 2.8 W per pole, or 8.4 W total for the 3-pole unit — relevant for thermal management inside a sealed enclosure.
