YX7310


3P3W Voltage Protection Relay

Voltage protection relay uses a high-speed and  low-power processor as its core. When the power  supply line has over-voltage, under-voltage, or  phase failure, phase reverse, the relay will cut off  the circuit quickly and safely to avoid accidents  caused by abnormal voltage being sent to the  terminal appliance. When the voltage returns to  the normal value, the relay will turn on the circuit  automatically to ensure the normal operation of  the terminal electrical appliances under  unattended conditions.

1. Cut off the line when Over & Under Voltage occurs,  and automatically reset and connect the line after  returning to normal without manual operation.

2. When the line appears transient or transient Over  & Under Voltage, the protector does not malfunction.
