Monitoring relays

Main goal of the voltage monitoring relays is to protect appliances from high and low voltage and neutral wire break. The relay operates on the cutoff principle: if the set values​ are exceeded, it turns off the load. Brand ZUBR has been on the market for 20 years and is now highly regarded by Ukrainian electricians. And now we are becoming increasingly popular in European Union countries like Poland, Lithuania, Czech Republic, Romania and others.

We invite you to watch a short video review about the ZUBR voltage monitoring relays range on our YouTube.

ZUBR 3F

ZUBR 3F

Three-phase voltage relay with TrueRMS and ProModel

Designed to protect domestic and industrial equipment (including three phase motors) from exceeding permissible voltage limits. A contactor must be used to control the three phase equipment.

ZUBR V3

ZUBR V3

Digital three-phase voltmeter.

Allows to monitor the quality of power supply of the three phase network, helps to detect sticking and violation of the phase sequence. The voltage is displayed on the digital screen.

ZUBR VA-1 red

ZUBR VA-1 red

Digital single phase volt-ampere meter. Expected in November 2024

Allows to monitor the quality of power supply of a single phase network. Measures: voltage, current, power (active, reactive or full) and cos φ. The network deviation log is able to store 100 deviation values in the nonvolatile memory.

ZUBR V1

ZUBR V1

Digital single phase voltmeter. Expected in November 2024

Allows to monitor the quality of power supply of a single phase network. The voltage value is displayed on the digital screen.

ZUBR D16

ZUBR D16

Single phase voltage relay. Expected in December 2024

Helps to protect electrical equipment from excessive voltage fluctuations in the network. The relay switches off the load when a critical situation occurs. The load supply is resumed after the delay time has ended. Mostly used with contactors (magnetic starter, power relay).

ZUBR D

ZUBR D

Single phase voltage relay. Expected in December 2024

ZUBR D25-63 voltage relays are designed to protect equipment from excessive voltage fluctuations in the network. When an emergency occurs, the relay cuts off the load. The load supply will be resumed after the delay time has ended.
