FKV-04NHF-V2 Phase Failure, Voltage & Phase Sequence Protection Relay

FKV-04NHF-V2 is a multifunctional three-phase protection relay designed for 3P4W (380V) systems. It integrates phase failure, over/under voltage, phase imbalance and phase sequence protection in one compact unit.

With adjustable voltage thresholds and imbalance settings, the relay ensures stable operation of motors, distribution panels and industrial equipment. The built-in phase sequence detection effectively prevents reverse phase damage, improving system safety and reliability.
