The contactor is rated for AC-3 switching at up to 1,000 operating cycles per hour, which covers most motor starting duty cycles for pumps, fans, and conveyors.
The AC-4 rating drops to 300 ops/h, reflecting the more severe inching or plugging duty cycles. Switching capacity varies with voltage: at 24 V rated value it handles 6 A, at 400 V rated value it handles 3 A, and at 440 V rated value it handles 0.6 A. These are the maximum currents the main contacts can make and break under the respective voltage conditions. The contactor operates between -25 and +60 °C during operation and can be stored from -55 to +80 °C.
