Welrok D2-63 red Voltage Relay

Welrok D2-63 red voltage relay is designed to protect electrical equipment from voltage surges and fluctuations in the electrical network.

Main characteristics:

• Nominal voltage: 230 V single-phase
• Maximum switchable power: up to 3 kW
• Installation: on 35 mm DIN-rail
• Contact type: electromechanical changeover contacts
• Lower threshold adjustment range: 160–210 V
• Upper threshold adjustment range: 240–280 V
• Response time: less than 0.5 seconds
• Hysteresis: 10–15 V

Functionality:

The relay is equipped with two independent trip thresholds — lower and upper. When the voltage drops below the set minimum or exceeds the maximum value, the relay opens the contacts and disconnects the power supply to the protected device. The red housing provides good visual identification on the panel.

Application:

Used to protect single-phase equipment in networks with unstable voltage: pumps, refrigerators, power tools, heating boilers and other household appliances.
