TOMZN Voltage and Current Protection Relay High Low Voltage Current Lightning Protective Monophase 40a Electric Guard Product features In case of single-phase line overvoltage failure, undervoltage failure or overcurrent failure, the product can turn off the line and automatically restore the connection of the line with a time delay after the voltage or current of the line returns to normal state.

In case of transient overvoltage in the line, the product can protect the equipment against faulty operation.

The product will cut the line in case of sudden shutdown and opening due to unstable voltage exposure of the line or loose connection or other failure.

When the fault voltage of the line reaches its peak, the product itself is not damaged
