Welrok D6-40 red Voltage Relay

Welrok D6-40 red Voltage Relay is designed to protect electrical equipment from voltage fluctuations in single-phase alternating current networks.

Main Characteristics:

• Rated Voltage: 230 V, 50 Hz
• Operating Range: adjustable for upper and lower thresholds
• Rated Load Current: up to 40 A
• Contacts: electromechanical, changeover type
• Degree of Protection: IP20
• Installation: on DIN-rail
• Dimensional Size: compact design (2 modules in width)

Functions:

The relay disconnects the load when the voltage goes beyond the set limits (upper and lower threshold). It provides time delay of operation to prevent false triggering during brief voltage surges.

Application:

Applied in power supply systems of private houses, cottages, and industrial facilities for protection of boilers, pumps, refrigerators, and other electrical equipment sensitive to mains voltage fluctuations.

Operating Conditions:

Temperature range: -10…+40 °C, air humidity up to 80% at 25 °C.
