Terminal capacity accepts 2x (0.25 to 2.5 mm²) solid or 2x 24–14 AWG stranded — use ferrules for stranded wire to avoid whiskers under the screw clamp.
Contact ratings and coil draw
The coil pulls 3.2 W DC both on pickup and hold — no economizer circuit, so the thermal load on the DC supply is constant. Contact ratings are given per voltage: 10 A at 24 V, 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. These are thermal current ratings for the auxiliary contacts; for inductive loads, derate per the switching frequency and load type.
