The contactor is rated for 1 000 switching cycles per hour at AC-1 (resistive loads), 750 cycles/h at AC-2 and AC-3 (slip-ring and squirrel-cage motors), and 250 cycles/h at AC-4 (plugging/inching duty). The AC-3e rating matches the AC-3 figure at 750 cycles/h. If your application involves frequent reversing or jogging, the AC-4 limit governs — exceeding 250 cycles/h in that duty class will shorten contact life.
Wire range accepts solid or stranded 0.5–4 mm², or two conductors per terminal (2x 0.5–1.5 mm², 2x 0.75–2.5 mm², 2x 4 mm²).
The built-in auxiliary switch is rated for 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 0.2 A at 440 V. At 230 V the rating is given as 2 hp. At 400 V it carries 3 A. These are the contact ratings for the auxiliary circuit — match them to your PLC input or relay coil draw.
