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 CV2

Single phase voltage relay with current control for 2 modules with thermal protection, TrueRMS, ProModel. Production suspended

40 A 50 A 63 A

Voltage relay with streak control ZUBR CV2 with thermal protection for protection of single-phase voltage fluctuations in the streak, strum substitution or general tightness, with a possible review of some kind of tension in the electrical meter (cos φ).

NEW

ZUBR MF2 red

Multifunction relay for 2 modules with thermal protection, TrueRMS, ProModel

40 A 50 A 63 A

Multifunctional relay ZUBR MF2 red with thermal protection is designed to protect single-phase electrical equipment from voltage, current or power deviations with the ability to view the power factor in the power grid (cos φ).

ZUBR D2 red

Single phase voltage relay for 2 modules with thermal protection, TrueRMS, ProModel

32 A 40 A 50 A 63 A

ZUBR D2 red voltage relay with thermal protection is designed to protect the equipment from excessive voltage fluctuations in the network. There are two types of delay time after emergency actuation. The alarm log can store the last 100 emergency situations in the nonvolatile memory.

ZUBR CV2 red

Single phase voltage relay with current control for 2 modules with thermal protection, TruRMS, ProModel

32 A 40 A 50 A 63 A

Voltage relay with excess of the gap ZUBR CV2 red voltage with protection against single-phase drops in the gap, replacement of the branch or common, with the possibility of viewing any voltage in the electricity meter (cos φ).

ZUBR D2

Single phase voltage relay for 2 modules with thermal protection, TrueRMS, ProModel

40 A 50 A 63 A

ZUBR D2 voltage relay with thermal protection is designed to protect the equipment from excessive voltage fluctuations in the network. There are two types of delay time after emergency actuation. The alarm log can store the last 100 emergency situations in the nonvolatile memory.

ZUBR R1

Household voltage relay with thermal protection, TrueRMS, ProModel

Ideal for protecting from excessive voltage fluctuations of any household device (for example, refrigerator) with a capacity of up to 3000 VA. A feature of the relay is its installation in a "euro" socket.

ZUBR D6 red

Voltage relays with operating modes: single-phase and three-phase load.
Resumption of production from July 2025

40 A 63 A

In single-phase load mode the functions of three-phase relays with independent settings are performed. In three-phase load mode and control common to all power relays, this device will build equipment from exceeding allowable limits and control maximum phasing, phase rotation and phase loss.

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

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

Digital single phase volt-ampere meter.

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

Digital single phase voltmeter.

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

ZUBR D16

Single phase voltage relay.

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).
