Welrok D2-50 Voltage Relay

Welrok D2-50 Voltage Relay — a protective device for electrical networks against voltage fluctuations.

Primary Purpose: Designed for automatic load disconnection when voltage exceeds or falls below established limits. Protects electrical equipment from mains voltage instability.

Relay Characteristics:

• Rated Voltage: 230 V, 50 Hz
• Rated Current: up to 50 A (according to D2-50 marking)
• Actuation: monitors upper and lower voltage thresholds
• Response Delay: adjustable time delay to prevent false disconnections
• Degree of Protection: IP20

Application:

• Protection of residential and industrial consumers (boilers, pumps, compressors)
• Network instabilities in rural areas and during emergency conditions
• Prevention of expensive equipment failure

Design: Compact relay device for mounting on DIN-rail in distribution cabinet. The controlled contact closes/opens the load supply circuit according to the voltage sensor signal.
