It carries a 100 kA breaking capacity at 400 V, 500 V, and 690 V, with a Class 10 trip characteristic — that's the standard thermal-magnetic curve for protecting standard induction motors against overload and short circuit. The 45 mm width fits a standard modular enclosure grid.
The same 100 kA holds at 500 V and 690 V, so it covers 480 V and 600 V class systems without derating the interrupt rating. Class 10 trip gives a maximum 10-second trip time at 600% of the thermal setting, matching the heating curve of a standard 4-pole induction motor during a locked-rotor start. The maximum switching rate is 15 operations per hour under AC-3 duty — that's the motor-starting load cycle, so it's not rated for frequent jogging or inching applications. Auxiliary contact ratings span the control-voltage range: 1 A at 24 V, 2 A at 110–125 V, 0.5 A at 230 V. For DC switching, it's 0.15 A at 60 V. The main contact terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire — M3 screw terminals, standard for this class. The depth is 75 mm, height 90 mm, width 45 mm. Clearance distances: 20 mm upwards and downwards, 9 mm at the side, 0 mm forwards and backwards — meaning it can be mounted flush against a panel backplane or adjacent devices on the same DIN rail.
