The main power terminals accept stranded cable from 25 to 120 mm², which covers most motor feeders up to the S6 frame rating. Mounting is by screw fixing with a single 9 mm hole. The enclosure footprint is 172 mm high by 120 mm wide by 170 mm deep.
Switching Performance and Duty Ratings
The contactor is rated for AC-3 duty (motor switching) at up to 1000 operating cycles per hour, and for AC-3e at the same rate. For heavy-duty AC-4 (inching, plugging) the maximum is 130 cycles per hour. AC-1 (resistive) allows 800 cycles per hour, and AC-2 (slip-ring motor) allows 400 cycles per hour. These ratings define the thermal and mechanical limits for repetitive switching — a buyer specifying a high-cycle conveyor or crane application should match the duty class to the actual load profile. The auxiliary contact ratings are 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V.
The coil pickup factor is 0.8 x rated voltage and 1.1 x rated voltage — meaning the coil will pick up reliably at 88 VAC on a 110 VAC system, and will hold in at 139.7 VAC on a 127 VAC system.
