General
FKV-12N phase failure relays are designed to prevent failure of 3-phase motors through the mains.
Use and principle of operation
Perform the device connections according to the connection scheme.
When the power supply is turned on and the phases are in normal values, the relay pulls and the LED from the relay is turned on. In this case, the contact (NO)3. Each of the phases rises or decreases compared to normal values, the relay is triggered and the LED turns off. In this case, the contact output (NC)1.
Care
Turn off the device and disconnect from the connectors. Clean the boot of the device with a cotton swab. Do not use conductors or chemicals.
