Welrok VI-63 Voltage Relay with Current Control

The voltage relay with current control function Welrok VI-63 is designed to protect electrical equipment from voltage surges and dips, as well as to monitor the parameters of consumed current in alternating current networks.

Field of Application:

• Protection of household and industrial electrical appliances
• Monitoring of supply voltage in local networks
• Automatic shutdown of equipment when parameters exceed permissible limits
• Use in distribution cabinets and at electrical energy input points

Basic Functionality:

• Two-level voltage control (upper and lower trip thresholds)
• Load current monitoring with adjustable shutdown thresholds
• Electromechanical or electronic operating principle
• Relay contacts for controlling external devices (contactors, magnetic starters)
• Trip delay to prevent false triggering

Technical Characteristics:

• Rated voltage: 230 V (single-phase design)
• Permissible voltage deviation range: ±20-30% from rated value
• Switched load current in control circuit: up to 16 A
• Response time: 0.1-1 sec (depending on trip type)
• Degree of housing protection: IP54 or IP65
• Mounting: on DIN rail in distribution cabinet

The relay ensures reliable equipment operation under unstable electrical network voltage conditions.
