Product functional features

■ Smoke and combustible gas protection function: When the smoke, liquefied petroleum gas, natural gas, propane, butane and other combustible gases in the electric field exceed the limit, the protector will emit an audible and visual alarm signal, automatically cut off the power supply, and display real-time fault records.
Short circuit protection function: The protector monitors the current of the power line in real time. When a short circuit fault occurs in the line, it can achieve fast current limiting protection within 0.1 seconds and display real-time fault records.

■ Overload protection function: When the current of the protected circuit is overloaded and the overload duration exceeds the action time (3-60 seconds can be set), the protector starts current limiting protection and displays real-time fault records.
Overvoltage protection function: When the protector detects under voltage or over-voltage in the line, it automatically cuts off the power supply and displays real-time fault records.

■ Distribution cable temperature monitoring function: When the temperature of the monitored cable exceeds the alarm set value, the protector automatically cuts off the power supply and displays real-time fault records.

■ Leakage current monitoring function: When the leakage of the monitored line exceeds the alarm set value, the protector automatically protects and cuts off the power supply, and displays the fault record in real time.

■ Communication networking function: The protector has one RS485 interface, which can send data to the background monitoring system, realizing the five remote functions of remote telemetry, remote signaling, remote control, remote adjustment, and remote viewing.

■ Simultaneous cutting of neutral and live wires: When a fault occurs in the circuit, the product cuts off both the neutral and live wires simultaneously, without the danger of live wires on the circuit due to the failure of the neutral wire to be cut off.

Overvoltage does not damage: When the three-phase power supply is misconnected, the maximum power supply voltage is at AC450V, and the product will disconnect within the set time, while the ground product itself will not be damaged due to high voltage.
Anti harmonic: Currently, the electricity consumption in the power grid is relatively complex, with a large number of harmonics present. Harmonic hazards can shorten the lifespan of other electrical equipment, but this product is not affected in harmonic power grids.
One click recovery function: When users are not proficient in product operation and cannot meet on-site protection requirements for parameter settings, they can easily restore the factory settings to avoid erroneous protection issues caused by improper operation.
