The 4.5 kA breaking capacity at 230 V AC (Icn per IEC 60898-1) covers most domestic and small commercial service entrances; the same 4.5 kA holds at 400 V AC for two-pole 400 V line-to-line loads. Thermal-magnetic trip unit, rated insulation voltage 500 V AC, impulse withstand 4 kV.
The 36 mm width (2 module pitches at 18 mm each) is a compact 2-pole footprint; with 81 mm height and 66.5 mm depth, it fits flush in a 4-row enclosure without crowding the gland plate. Tightening torque 2 N·m.
4500 A Icn at both 230 V AC and 400 V AC, 50/60 Hz, conforming to IEC 60898-1. The service breaking capacity (Ics) is 4.5 kA at 100 % of Icn at 230 V AC.
Designed and certified to IEC 60898-1. Rated insulation voltage 500 V AC, rated impulse withstand voltage 4 kV. Suitable for isolation per the same standard. IP20 degree of protection. Pollution degree 2.
