The AC-3 maximum switching voltage is 690 V, so it handles 400 V and 690 V motor circuits within the same frame.
RoHS compliance date is 05/01/2012. Insulation voltage is 690 V, pollution degree 3.
Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Minimum conductor size at 40 °C and 60 °C is 10 mm². Coil data: 24 V at 50/60 Hz, draws 6 A at 24 V rated value (likely inrush), with holding current lower. The 0.25 A at 50 Hz and 0.28 A at 60 Hz are the steady-state coil draws — factor these into your 24 V control transformer sizing.
Switching performance and mechanical life
Maximum switching frequency at AC-3 is 750 cycles per hour; at AC-4 it drops to 250 cycles per hour. For high-duty-cycle applications like frequent reversing or jogging, the AC-4 limit governs — stay under 250 ops/h to avoid contact welding.
