It is rated 100 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which means it can safely interrupt a fault up to that level without welding contacts or cascading upstream. The 160 A frame rating at 40 °C sets the continuous current limit for the assembly; the actual trip curve comes from the plug-in trip unit (not included).
Breaking capacity is the headline figure: 100 kA Icu at 415 V AC, with 120 kA at 240 V and 90 kA at 440 V. The Ics (service breaking capacity) matches the Icu at every voltage level — meaning the frame can be reclosed after a fault at full rated current without derating, a requirement for main incomer duty in many panel designs. The 8 kV impulse withstand voltage (Uimp) and overvoltage category III confirm it is built for fixed-installation distribution boards, not plug-in equipment. Mechanical durability is 40,000 cycles; electrical durability ranges from 40,000 cycles at 440 V at half rated current down to 7,500 cycles at 690 V at full rated current.
Fixed mounting on a backplate, 140 mm wide × 161 mm high × 86 mm deep. The 35 mm connection pitch and front-connect terminals (both upside and downside) suit standard panel layouts with busbar or cable entry from the front. IP40 enclosure protection means it is suitable for indoor switchboards where no water spray is present; the IK07 impact rating handles incidental tool contact during installation.
