Voltage relay with current control VA- 25AG3R
Voltage relay VA-25A G3R with current control is designed to protect electrical devices and household appliances from unacceptable voltage fluctuations. The device continuously analyzes the mains voltage and, if it is exceeded, the connected devices are switched off, and the load is switched on automatically after the voltage returns to the preset range. The user sets the required upper and lower voltage limits and the time of the switch-on delay.
The switch-on delay is required for electrical devices that do not tolerate short power outages (refrigerators, air conditioners, etc.).
The device also monitors the current consumption of the connected load, as there are a number of abnormal situations occurring due to excess current: the most common is when the wiring heats up, the most critical is a "short circuit". If the maximum current is exceeded, the load is immediately turned off. The load is switched on by a button on the front of the device.
