FAQs
Installation involves wiring the three main NO contacts and the single auxiliary NO contact to your motor control circuit using screw terminals. Tighten main circuit terminals to 2.3 N·m and auxiliary/control terminals to 1 N·m as specified. Mount the unit in a compliant enclosure with IP20 protection on exposed connections to ensure safe operation and ease of maintenance.
For AC-3 operation at 690 V, the device is rated up to 25 A per pole. This supports motor start/stop duty with predictable performance, suitable for drives, conveyors, and other high‑voltage motor loads while maintaining thermal integrity under typical ambient conditions.
Yes. The product carries CE declarations, UL certificates, and CCC documentation, along with RoHS/REACH compliance. These certifications support global deployments, ensuring conformity with European, North American, and Chinese regulatory requirements.
The control coil operates at 48 V with a frequency of 50 Hz or 60 Hz, allowing compatibility with standard control circuits and PLC logic without additional adapters or power supplies.
Best suited for controlling 3-phase motors in conveyors, pumps, and machine tools, particularly where 690 V line voltage, 3-pole main contacts, and a built‑in auxiliary contact are advantageous. Its compact form, accessible screw terminals, and optional auxiliary blocks simplify integration into existing control panels and new equipment.
