Product details

The coil draws 10 A at 24 V rated value, with a pick-up threshold of 0.8 x rated voltage and a drop-out of 1.1 x full-scale value — meaning the contactor holds in reliably down to about 19.2 V and releases cleanly above 26.4 V.

Duty-cycle and switching frequency

Maximum switching frequency depends on the load duty: 1 000 operations per hour for AC-1 (resistive), 750/h for AC-2 and AC-3 (motor starting/running), and 250/h for AC-4 (plugging/inching). The AC-3e rating also allows 750/h. These limits govern thermal rise in the coil and contacts — exceeding them shortens life or causes nuisance tripping.

Main circuit terminals accept solid or stranded wire from 1 to 10 mm², with auxiliary contacts accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. The screw-type terminals are standard for panel wiring.
