Welrok D2-63/2 Voltage Relay

Two-pole voltage relay designed to protect electrical equipment from fluctuations in mains voltage.

Main Characteristics:

• Rated Voltage: 230 V AC
• Number of Poles: 2
• Rated Current: 63 A
• Protection Type: voltage monitoring with disconnection when values exceed permissible limits

Functional Purpose:

The relay automatically disconnects the load when:

• Voltage drops below the minimum threshold (undervoltage protection)
• Voltage rises above the maximum threshold (overvoltage protection)
• Phase symmetry is disrupted in a three-phase network

Application:

Used in electrical supply systems of residential and industrial facilities to protect household appliances, pump stations, compressors and other equipment sensitive to voltage fluctuations. Suitable for installation in distribution panels and control cabinets.

Installation: DIN-rail (modular installation)
