63A 220V Adjustable DIN rail surge and undervoltage protection device with relay and overcurrent protection for home use with two LED indicators

The circuit breaker with dual LED indicator is suitable for single-phase 220V AC power supplies (50/60Hz) with a rated current of 63A. It is primarily used for connection to household electrical distribution boards or to protect distribution lines from overvoltage, undervoltage, and overcurrent for single-phase electrical appliances. Its main feature is the immediate power cut-off in the event of overvoltage, undervoltage, or overcurrent to protect electrical equipment from damage. Once the voltage in the circuit returns to normal, the circuit breaker automatically resets. The overvoltage, undervoltage, and overcurrent thresholds can be set by the user and adapted to local conditions. Functions: Voltage and current protection – Cuts off the power supply in the event of overvoltage, undervoltage, or overcurrent. Protects your electrical appliances from damage. Automatic reset – Reconnects the power supply once the voltage and current in the circuit return to normal. Adjustable – within a voltage range of 230 V to 300 V, below a voltage range of 140 V to 210 V, and with a current of 1 to 63 A. Adjustable recovery time from 1 to 600 seconds. Dual LED display – Two digital LED displays show voltage and current independently, allowing for easier and clearer readings. Can be used as a voltmeter and ammeter. Customizable – Overvoltage, undervoltage, and overcurrent values of this product can be individually set and adapted to local conditions. Specifications: Nominal supply voltage: 220 V AC.
