At 400 V it's 30 kA, at 500 V it's 6 kA, and at 690 V it's 3 kA. If your panel sees a high available fault current at the lower voltage, this part covers it.
Trip Class and Duty Cycle
The maximum switching rate is 15 operations per hour in AC-3 duty (motor starting), so it's fine for normal process cycling but not for a rapid-reversing application.
Mounting and Envelope
Dimensions are 75 mm wide, 140 mm high, 149 mm deep. It mounts in any position, with clearance requirements: 50 mm above and below, 10 mm to the sides, and zero clearance forward and backward. That's a tight envelope for a 100 kA device — you can pack it into a compact panel as long as you respect the top and bottom ventilation gaps.
Main circuit terminals are screw-type, accepting 2× (1–25 mm²) or 1× (1–35 mm²) solid or stranded copper. The main contact terminal size is M6. That's a generous wire range — you can land a 35 mm² feed without a reducer, and still have room for a second conductor if you're looping through.
