Product characteristics

1. Fault arc detection

XUCKY uses a high-speed and high-precision sampling ADC to extract key information about electrical parameters, such as arc occurrence time, arc amplitude, arc duration, etc. , the neural network algorithm has better generalization ability and higher discrimination accuracy under big data, and it can distinguish normal arc and fault arc, ensure no leakage and no error.

The tripping characteristics are shown in the following table:

Tripping curve:

2.Residual current protection

This product implements B+ type residual current protection function, which can identify residual current faults of different frequency AC (150KHz), pulsating DC, smooth DC and their composite situations.

The tripping characteristics are shown in the following table:

Tripping curve:

3.overcurrent protection

This product uses high-precision chips to accurately collect real-time current in the circuit. With calibration and temperature compensation mechanisms, it is minimally affected by environmental temperature changes, ensuring high accuracy and reliable overload protection. The instantaneous trip selection is primarily based on magnetic trip, with electronic trip as a backup, providing a dual safety measure of electromagnetic and electronic trip.

The tripping characteristics are shown in the following table:

Tripping curve:

4.Over-voltage protection

The over-voltage and under-voltage protection of this product uses high-precision sampling circuit to accurately judge whether the voltage reaches the threshold, and immediately open the circuit, to avoid voltage fluctuations damage home appliances.

The tripping characteristics are shown in the following table：

Tripping curve:

5.Equipment self-test

This product has manual detection function. Long press the detection button "T" on the surface of the switch, and the switch will automatically generate residual current detection signal and fault arc signal. When two kinds of fault signals are detected, the switch is disconnected and the self-test is successful; If there is a self-test failure, the switch is constantly on, four indicators are steady on, the circuit breaker itself is faulty, need to replace the circuit breaker. The manual detection function of this product needs to be pressed once a month to ensure timely detection of equipment faults and ensure user safety.

This product has automatic detection function. When the switch is powered on for the first time or every 1 hour of continuous operation, automatic fault arc detection is carried out inside the equipment. The self-test is successful, and the equipment continues to work; The self-test fails, the switch is constantly on, the four indicators are steady on, the circuit breaker itself is faulty, and the circuit breaker needs to be replaced. 5.Failure indication

Indicator light status information

This product is equipped with 4 LED indicator lights, each indicator lamp respectively by off, always bright, flashing three kinds of shape. The information represented by the different indicator states is shown in the following table

6.Troubleshooting

Please contact the professional for troubleshooting when the fault indicator shows that there is a fault, or when the product is off-loaded due to other unknown reasons。
