FAQs
Install using the screw terminals, wire the main circuit to the 3 NO contacts and the control circuit to the rated coil voltage (50 Hz 105 V or 60 Hz 110–127 V). Tighten control circuit terminals to 1 N·m and main circuit terminals to 4 N·m. Ensure IP20 coil terminal protection and provide proper strain relief for all cables.
For AC-3 operation at 690 V, the device provides a rated current of up to 43 A, with a corresponding rated power up to 37 kW (depending on exact voltage). It also supports short-time withstand currents and a maximum electrical switching frequency of 600 cycles per hour, ensuring reliable motor starting and stopping sequences.
Yes. The contactor supports ambient temperatures from −25 to 55 °C when equipped with a thermal overload relay; without the relay, it operates from −40 to 70 °C. Altitude ratings extend up to 3000 m without derating, making it suitable for installations in higher elevation facilities.
It carries CE conformity, UL/CSA general-use ratings, and CCC/CQC declarations, along with RoHS and REACH compliance. These certifications help meet global wiring safety standards and environmental regulations, reducing compliance risk in multinational installations.
Low loss operation (6.5 W per pole in AC-1, 1.5 W per pole in AC-3) reduces energy waste. With a mechanical life of up to 3600 cycles per hour and CIP-friendly screw terminals, maintenance intervals extend and downtime drops. The compact design and accessory compatibility also minimize panel rework and spare part diversity, delivering a favorable total cost of ownership.
