## Summary description

FF CP-709 is a single-phase voltage monitoring relay designed to protect electrical circuits by monitoring supply voltage ranges 150–210V and 230–260V AC. It features a 1P contact configuration and 16 A switching capacity, providing automatic disconnection on under- or over-voltage. Suitable for motor and equipment protection, distribution boards, and industrial or commercial installations.

## Long description

FF CP-709 is a single-phase voltage monitoring relay designed to monitor and protect electrical installations against under-voltage and over-voltage conditions. The device operates with selectable supply ranges of 150–210 V AC or 230–260 V AC and provides a single-pole (1P) switching contact with a rated switching capacity of 16 A. FF CP-709 disconnects the load automatically when supply voltage moves outside the selected window, helping to prevent damage to motors, control equipment and other connected devices.
Advantages
The relay offers straightforward voltage surveillance with a compact 1P design and a clear switching rating of 16 A for typical motor and equipment circuits. Its dual selectable operating ranges make it adaptable to different single-phase supply systems. The automatic disconnection on under-voltage and over-voltage reduces the risk of equipment failure and simplifies protection schemes in distribution boards and control panels.
Suitable for
 Protection of single-phase motors and pumps
 Monitoring supply to control equipment and compressors
 Integration in distribution boards and industrial control panels
 Commercial and light industrial electrical installations
Key specifications

How to use
Install the FF CP-709 in accordance with local electrical codes and mount it in a suitable distribution board or control enclosure. Select the appropriate voltage window (150–210 V or 230–260 V) that matches the supply being monitored. Connect the supply and load to the relay terminals following the wiring diagram provided by the manufacturer and ensure secure connections. After wiring, apply power and verify correct operation by testing the relay response to voltage conditions within and outside the selected range.
Usage recommendations
For reliable operation, place the relay in a ventilated enclosure away from excessive heat and moisture. Verify compatibility of connected loads with the 16 A switching capacity and consider using an external contactor for larger motor starters. Periodically inspect wiring and terminal tightness and perform functional tests after installation or maintenance.
