Voltage Relay Welrok D6-63

Welrok D6-63 series electromechanical voltage relay for protection of electrical equipment from power supply voltage fluctuations.

Purpose

The device is designed for automatic load disconnection when voltage goes beyond the established limits (upper and lower threshold levels). It is used in power supply systems of residential, commercial and industrial facilities to protect electrical consumers from voltage surges and sags.

Technical Characteristics

• Nominal voltage: 230 V (single-phase)
• Network frequency: 50 Hz
• Contact system: electromechanical
• Accuracy class: complies with GOST requirements
• Load current: up to 63 A
• Adjustment range: standard for power supply voltage 90–280 V
• Response time: 0.5–5 sec (adjustable)
• Installation: on DIN-rail

Features

• Separate adjustment of upper and lower trigger thresholds
• Built-in status indication
• Compact housing, space-saving on panel
• Reliable contacts with enhanced switching capacity

Application

Protection of refrigeration equipment, pumps, compressors, power tools and other devices from damage during voltage instability in the network.
