The 20...690 V rated range covers standard low-voltage industrial supplies worldwide.
The maximum switching rate is 15 operations per hour under AC-3 duty, which governs motor starting and plugging. Auxiliary contact ratings are given for multiple voltages: 1 A at 24 V, 2 A at 110/120/125 V, 0.5 A at 230 V. These are the switching capacities for the internal auxiliary contacts — useful for PLC inputs or status indication. The main contact terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded wire, M3 screws. Dimensions: 45 mm wide, 75 mm deep, 90 mm high. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm at the side, 0 mm forwards/backwards — so it can be stacked tightly side-to-side but needs vertical breathing room for arc quenching.
