The coil is rated 24 V DC, and the contactor carries a DC-13 switching capacity of 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. For AC motor duty (AC-3), the contactor is rated for 750 switching operations per hour; for resistive loads (AC-1), it handles up to 1 000 cycles per hour. The arcing time falls between 10 and 15 ms, and the DC switching delay is 7 to 13 ms. Mechanical life is typically 30 000 000 operations. Conductor cross-section accepts 0.5 to 4 mm² solid or stranded, and 2x (0.5 to 4 mm²) for double ferrule.
