The J7KNA-AR-31 24D: AC contact ratings step down with voltage: 3 A at 220–240 V, 2 A at 380–415 V, 1.6 A at 440 V, 1.2 A at 500 V, and 0.6 A at 660–690 V. That 10 A headline number is the thermal current; the real switching limit is the voltage-specific row. For a 230 V control circuit you get 3 A; for a 400 V pilot circuit you're down to 2 A. DC ratings are lower still — 2 A at 60 V, 0.4 A at 110 V, 0.1 A at 220 V — because DC arcs don't self-extinguish at zero-cross. If you're switching a DC solenoid or brake coil, size for the DC row, not the AC one.
