ZUBR D6-63 red Voltage Protection Relay 3P 3NO 63A

ZUBR D6-63 red — three-phase voltage protection relay designed to protect domestic and industrial electrical equipment (including three-phase electric motors) from overvoltage and undervoltage.

The device has 2 operating modes: it can operate as 3 single-phase relays with different settings or as 1 three-phase relay. The device memory stores the last 99 relay activations.

ZUBR D6 red uses the True RMS network voltage measurement method, reducing voltage disturbances from the network and ensuring accurate voltage measurement.

Additional protection settings:

• Maximum number of relay activations;
• Voltage hysteresis.
