Adjustable Over Voltage Under Voltage Protector Circuit Breaker

Circuit Breaker(Automatic Over and Under Voltage Protector) complies with modular design standards. the circuit boards of products adopt good quality electronic components with reliable performance. when the power situation is unstable. It's protection function will be automatically activated. once the voltage exceeds the limited range of products, it will automatically cut off so as to protect the safely of electrical equipment and persons. The device will re-supply in 1 minute, when the power returns to normal.

The green indicator display, when the power is normal supply.

The red indicator display, when the power over voltage or under voltage.

Installing: 35mm Din rail.

Purpose
It is intended for a circuit of AC 50Hz/60Hz with maximum rated current of 63A to protect it and the equipment involved against overvoltage, low voltage, current surge, leakage, lightning, etc.
It is applicable to such electrical equipment as communication base stations, repeaters, video surveillance, Safety City, cable TV, digital TV, network switches, optical transceivers, meteorological telemetry stations, seismic detection stations in various conditions.

Features
Detection before closing: The automatic reclosing power protection switch monitors the circuit and will not close in occurrence of any overvoltage, leakage, overcurrent and other failures.
Overvoltage protection: When the voltage between the live wire and naught wire of the input terminal is greater than the set value, it will trip the switch for protection.
Low voltage protection: When the voltage between the live wire and naught wire of the input terminal is less than the set value, it will trip the switch for protection.
Overcurrent protection: When the actual current is greater than or equal to 1.15 times the rated current for 3 seconds, it will trip the switch for protection.
Leakage protection: When the leakage current exceeds the set value or an electric shock occurs, the automatic reclosing switch will be disconnected within 0.1 seconds to ensure personal safety.
Automatic disconnection when power's off: The switch will be automatically disconnected when the circuit is powered off, and will be automatically reclosed after detecting a normal power supply restored.
Intelligent leakage identification: Automatically detect before closing if the voltage is normal and the Neutral line is well-connected and never close in case of any failure.
Automatic reclosing: Automatically reclose after a certain time interval if the above failure occurs.
Automatically save tripping information: Automatically save such tripping information as tripping time, tripping type (cause), voltage, current and leakage current for failure analysis.
