The 24 V DC coil pulls in at 0.8 of rated voltage and drops out at 1.1 of rated voltage, per the datasheet figures. Spring-type terminals on the coil save a wiring step versus screw-clamp variants — no torquing, just strip and insert.
Main contacts are rated for 20 A through 12 A depending on duty category — the AC-1 resistive load curve is the highest, while AC-3 motor switching and AC-4 inching/jogging draw lower continuous ratings. For DC-13 solenoid loads, the contactor breaks 10 A at 24 V, 2 A at 48 V, and 0.3 A at 220 V, so it handles small DC brake coils or control transformers within those limits. The mechanical life is 30 million operations, and the maximum switching frequency varies by duty: 1 000 cycles/hour at AC-1, 750 at AC-2/AC-3, and 250 at AC-4 — the AC-4 figure governs if the application includes plugging or inching.
Mounting position is standing on a horizontal surface. Wire range for main and auxiliary circuits is 0.5 to 4 mm² solid or stranded, with 2 x (0.5 to 4 mm²) permissible for looping.
