Three-phase relays for phase control with shutdown protection and winding temperature control, TENSE - FKV-14P
Product description
The FKV-14P three-phase phase control relay is designed to protect three-phase electric motors and equipment from critical malfunctions in the power grid. It provides comprehensive control of phase presence, phase failure, phase interference, asymmetry (fixed 40%), incorrect phase sequence, and excessive motor winding temperature. Equipped with a neutral conductor and designed for DIN rail mounting.
Key features
-
Checks for the presence of all three phases
-
Protection against phase failure
-
Detection of phase interference (overload)
-
Fixed voltage asymmetry control at 40%
-
Protection against incorrect phase sequence
-
Motor winding temperature control
-
Optical status indication (LED OUT)
-
Automatic restart when parameters return to the allowed range
Operating principle
-
Normal operation: if all three mains voltages are present, the phase sequence is correct, and the winding temperature does not exceed the permissible limits, the relay switches on (contacts 15-18 are closed) and the OUT LED lights up.
-
Voltage fault or asymmetry: if the voltage of any phase differs by more than 40%, contacts 15-18 open and contacts 15-16 close; the OUT LED is off.
-
Phase sequence fault: the relay reacts by opening the contacts and turning off the OUT LED.
-
Winding temperature exceeded: the relay disconnects the output until the temperature returns to the permissible limits.
-
Operation recovery: After the parameters normalize, the relay automatically returns to the operating state.
