Voltage control relays

Voltage control relays monitor the value of alternating voltage in low-voltage electrical networks and protect equipment in the event of overvoltage, voltage drop, dropout or incorrect phase sequence.

In the category you will find single-phase and three-phase E.NEXT voltage relays, suitable for installation in electrical panels, residential, commercial and industrial installations.

What is a voltage control relay?

The voltage control relay is a protective device that monitors the parameters of the electrical network and disconnects the load when it deviates from the set limits. After the voltage normalizes, the device can automatically restore power according to the set delay time.

Single-phase and three-phase voltage relays

Single-phase voltage relays are mainly used in domestic and small commercial installations. Three-phase relays are suitable for industrial equipment, electric motors, pumps, compressors and machines where it is important to monitor not only the voltage value, but also the state of the phases.

What protection do they provide?

Where are they used?

Voltage control relays are used in electrical panels, automation systems, pumping installations, compressors, electric motors, production machines and equipment sensitive to unstable power supply.

Important when choosing

When choosing a voltage control relay, it is important to consider the type of network, the rated voltage, the permissible tripping limits, the reclosing time, the number of phases and the method of load control.

The voltage relay does not replace a circuit breaker or surge protector. For complete protection of the electrical installation, it is recommended to use it in combination with circuit breakers, contactors and surge protectors.
