Supervisory/protective three-phase relay for overvoltage, undervoltage, asymmetric sequence monitoring

Three-phase monitoring/protective relay for sequence control, disconnection, phase asymmetry, overvoltage, undervoltage, disconnection of the neutral part with a timer and display. Protective monitoring relay FKV-03HF (TENSE)

Phase protective relays are designed to protect three-phase loads from damage due to network voltage.
