Welrok VIP-63 Voltage Relay with Current Control

Welrok VIP-63 Voltage Relay with Current Control — an electrical network protection device designed for automatic load disconnection when voltage and current parameters exceed permissible limits.

Primary Purpose:

• Protection of electrical equipment from voltage fluctuations (overvoltage/undervoltage)
• Monitoring of load current excess
• Automatic power restoration when network parameters normalize

Functional Features:

• Separate adjustment of upper and lower voltage threshold values
• Maximum load current monitoring
• Adjustable response delay time (anti-chatter)
• Automatic recovery after network normalization
• Protection against multiple switching operations during unstable network conditions

Technical Parameters:

• Rated voltage: 230 V, 50/60 Hz
• Rated load current: 63 A
• Voltage control range: 150–280 V (adjustable)
• Compact design for DIN-rail mounting
• Protection class IP20

Application Area: Used in electrical supply systems of residential buildings, boiler rooms, pumping stations, for protection of household and industrial electrical appliances from instability of mains voltage.
