Tense DGK-04F digital three-phase overvoltage protection relay for DIN rail

The Tense DGK-04F microprocessor relay protection device is designed to provide comprehensive protection for sensitive industrial equipment and motors from risks associated with voltage fluctuations in three-phase networks. The device continuously monitors the network voltage and offers highly accurate protection against overvoltage, undervoltage, and phase sequence errors. A special feature of this model is its connectivity without the need for a neutral wire (asymmetric/three-wire networks).

The relay is equipped with digital displays for instant status overview of individual phases. The user can precisely set voltage threshold values and time delays to filter out short-term voltage spikes and prevent unwanted switching. The compact modular design ensures easy installation on a standard 35 mm DIN rail.

Main functions and protections

  • Overvoltage and undervoltage protection: Automatically disconnects the output if the voltage exceeds or falls below set limits.

  • Phase sequence monitoring: Prevents incorrect motor rotation direction in case of faulty phase connection.

  • No neutral: Ideal for systems where a neutral conductor is not available or required.

Technical specifications

  • Product type: Digital surge protection relay

  • Number of phases: 3 (three-phase connection without N)

  • Nominal operating voltage ($U_n$): 3× 380 V AC (50/60 Hz)
