The mechanical life is typical 30 million operations, and the maximum operating rate varies by duty: 1 000 cycles/h at AC-1, 750 at AC-2 and AC-3, and 250 at AC-4 (–).
The depth is 73 mm, width 45 mm, height 70 mm.
Switching Ratings and Duty
The contactor's switching capacity is specified per duty class. At AC-1 (resistive loads) the maximum operating rate is 1 000 cycles/h; at AC-3 (motor starting) it is 750 cycles/h; at AC-4 (inching/plugging) it drops to 250 cycles/h (–). These ratings tell you the contactor is sized for moderate-duty motor switching — not for high-speed jogging or heavy inching cycles.
