The 24 VDC coil is rated for continuous duty, and the contactor carries a mechanical life of 30,000,000 operating cycles typical — a figure that matters when you're spec'ing a spare for a high-cycle conveyor or pump station. You want one in the cabinet before it fails, not after.
Rated operational current at 24 V is 10 A (AC-12), which covers general-purpose resistive loads. For motor switching, the AC-2 rating at 400 V is 4 kW, and the AC-4 rating at 400 V is 8.5 A — these are the numbers that govern real motor duty, not the higher resistive figure. At 690 V the contactor is rated for 5.5 kW motor load, so it handles 400 V and 690 V three-phase systems without derating concerns within those limits. The auxiliary contact block is rated for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. If you're switching a 24 VDC PLC output or a DC brake coil, those numbers confirm the contactor can handle it without welding the contacts. 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 screw tightening needed — good for vibration-prone environments or when panel builders want consistent contact force without torque checks.
These are the values to hand to the panel designer when sizing the upstream protection.
