63A 220V Din Rail Adjustable Over Voltage and Under Voltage Protective Device Protector Relay Over Current Protection Home Usage Dual LED Display (Standard)

The double LED display adjustable voltage current protector is suitable for single-phase AC 220V, 50/60Hz, rated working current 63A. It is mainly used for residential household box entry or over-voltage, under-voltage or over-current protection of distribution lines for single-phase electrical equipment. Its main feature is when the circuit has over-voltage or under-voltage, over-current problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage returns to the normal. The over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition.

Features:
Voltage & Current Protection -- Cut off the power when the circuit has over-voltage,under-voltage or over-current. Protect your home electrical equipment from being damaged.
Automatic Reconnect -- Turn on the power supply when the circuit voltage and current returns to the normal.
Adjustable -- Over voltage value range 230V-300V, under voltage value range 140V-210V, over current value 1-63A. Fault recovery delay time adjustable from 1-600 seconds
Double LED Display --Two seleprate digital LED display can display the real voltage, current independently for easier and clearer reading, can be used as a voltmeter and ammeter.
Customizable -- The over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition.
