Voltage Monitoring Relays and Electrical Equipment Protection

ZUBR D2 is a single-phase voltage monitoring relay designed for installation in an electrical distribution board. It protects electrical equipment in homes, offices and other buildings against overvoltage, undervoltage and dangerous voltage deviations caused by neutral conductor failure. When the mains voltage exceeds the selected limits, the relay disconnects the load and restores power after the voltage has returned to normal. The relay is available as the ZUBR D2-40A and ZUBR D2-63A . It is suitable for protecting household appliances, heating equipment, refrigerators, air conditioners, computers and other devices sensitive to voltage fluctuations. ZUBR D2 does not replace a Type 1 or Type 2 surge protection device (SPD). It complements distribution board protection by disconnecting the load during dangerous mains voltage deviations.

ZUBR D6 is a three-phase voltage monitoring relay for installation in an electrical distribution board. It protects domestic and industrial electrical equipment, including three-phase motors, against overvoltage, undervoltage, phase imbalance, phase loss, incorrect phase sequence and the consequences of neutral conductor failure. The relay can protect either three independent single-phase loads or one three-phase load. Detailed settings and wiring diagrams are available in the manufacturer’s English ZUBR D6 web manual . ZUBR D6 is a voltage monitoring relay, not an impulse surge protective device. It does not replace a Type 1 or Type 2 SPD but can be used alongside one as part of a coordinated electrical protection system.

ZUBR Dt is a single-phase voltage monitoring relay with thermal protection. It protects domestic and industrial electrical equipment against dangerous overvoltage, undervoltage and voltage deviations caused by neutral conductor failure. The voltage relay is installed inside an electrical distribution board and disconnects the load when the voltage exceeds the user-defined limits. Heatline offers 25 A and 40 A models. ZUBR Dt is intended primarily for a standard 230 V mains supply with a sinusoidal voltage waveform. It is suitable for protecting household appliances, heating equipment, pumps, compressors, refrigerators and other voltage-sensitive equipment. Detailed settings and wiring diagrams are available in the manufacturer’s English ZUBR Dt web manual . ZUBR Dt is a voltage monitoring relay, not an impulse surge protective device. It does not replace a Type 1 or Type 2 SPD but can be used alongside one as part of a coordinated protection system.

The DS Electronics ZUBR 3F three-phase voltage relay is designed to protect household and industrial equipment, including three-phase electric motors, from excessive and undervoltage. The device monitors the phase sequence and switches off the load if phase asymmetry occurs. The load shutdown delay time can be set as needed.

Voltage relay with current control   DS Electronics   ZUBR CV2   protects devices from too high and too low voltage, neutral wire interruption, as well as excessive current or power consumption. In case of voltage deviations, the voltage relay switches off the load, and when the voltage returns to normal, it automatically switches the load back on. If the current or power exceeds the allowed value, the load is switched off after the set delay time.
