Sensor operated voltage relay for socket installation

Voltage monitoring relay ZUBR SR1 reliably protects connected electrical appliances from high and low voltage, as well as zero break. A special feature of the voltage relay ZUBR SR1 is its installation in a European socket — this is convenient if there is no space in the electrical panel.

Socket relays are a great solution, if it is not possible to install a relay on the DIN rail in the switchboard or you want to set a longer delay for compressor equipment, such as a refrigerator. If you want to protect several devices with a total power of up to 3 kW, use an extension cord.

Operation comfort

The relay operation is adjusted by using only four buttons. The screen displays the current voltage, system alerts, and simplifies menu navigation. Load supply will start after the delay time is over, which will be notified by the green indicator.

On delay

The relay will turn off the load when the permissible voltage is exceeded, and its supply will resume after a set delay time. You can adjust the duration of the delay time based on the type of equipment connected. For equipment sensitive to frequent voltage outages (for example, compressor equipment — refrigerators, air conditioners, etc.), we recommend setting the delay duration to 120-180 s.

With ZUBR SR1  voltage relay you can choose a professional voltage switch off model. It allows not to disconnect the load at safe values and duration of voltage deviations.

Safe usage

You can lock the buttons so that no one else changes the relay settings (for example, your children). The device is protected from overheating: when the temperature inside the housing rises to 80 °C, the relay will turn off the load and report overheating. The operation will resume after the temperature drops to 60 °C.
