Welrok D6-40 Voltage Relay

The Welrok D6-40 voltage relay is designed to protect electrical equipment from voltage fluctuations in the electrical network. The device automatically disconnects the load when the voltage goes beyond the established limits and restores power when the network parameters return to normal.

Primary Purpose:

• Protection of single-phase consumers of electrical energy
• Prevention of equipment damage during voltage surges
• Monitoring voltage within the range of operating values

Technical Capabilities:

• Separate adjustment of upper and lower shutdown thresholds
• Status indication of operation by LED
• Response delay to prevent false triggering
• Manual mode selector switch

Application:

• Protection of compressors, refrigerators, and pumps
• Use in workshops and industrial premises
• Domestic and small industrial installations
• Water supply and heating systems

The device is mounted on a DIN rail in a distribution panel and can be used either independently or as part of an automatic power supply control scheme.
