It carries a 24 VDC coil with an integrated diode surge suppressor, so the coil drop-out is clean and you don't need an external flyback diode on the DC supply.
Mounting and wiring — panel fit
Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG) — no screwdriver torque check needed, just strip 8 mm and push in.
The AC-12 rating at 10 A is the resistive-load maximum — use that for general-purpose switching. For motor duty, the AC-2 rating at 400 V gives you 4 kW, and AC-4 at 400 V gives 8.5 A for reversing or inching. The DC switching ratings cover your control circuits: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. That 10 A at 24 VDC is the one you'll lean on for most PLC-output loads. Type 2 coordination requires a 20 A gL/gG fuse upstream; Type 1 needs 35 A.
