Welrok D6-63 red Voltage Relay

Welrok D6-63 red Voltage Relay — a protective device for electrical networks against voltage fluctuations.

Main Characteristics:

• Rated Voltage: 230 V (single-phase)
• Rated Current: 63 A
• Activation Type: electromechanical relay
• Purpose: protection against inadmissible voltage rise and drop in the network
• Adjustment Range: upper and lower activation thresholds are set individually
• Activation Delay Time: adjustable (protection against short-term voltage surges)
• Protection Class: IP20
• Installation: on DIN rail
• Warranty: 2 years

Application:

The relay is used in electrical supply systems of residential, commercial and industrial facilities to protect connected equipment (boilers, refrigerators, air conditioners, pumps, etc.) from damage during unstable network voltage.

Operating Principle:

When the voltage goes beyond the set limits, the relay activates, breaking the contacts and disconnecting the load. After the voltage returns to normal, manual or automatic restart is required.
