Monitoring relays

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).

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 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.

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 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.

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.

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.

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.

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.

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

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 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.
