False tripping of arc fault circuit breakers may be caused by a variety of factors, and may include the following possible causes: Improper sensitivity setting: Arc fault circuit breakers usually trigger circuit disconnection by detecting arcs in the circuit. If the breaker's sensitivity is set too high, it may misinterpret normal arcs or other transient circuit abnormalities as fault arcs, thereby causing the breaker to trip falsely. Environmental interference: Factors such as electromagnetic interference, vibration, or temperature changes in the environment may affect the arc fault circuit breaker.

This situation is completely normal. The over-voltage and under-Voltage Protector only powers on after it detects that the voltage is normal and stable. For example, the JGGQ-100S/3P+N over-voltage and under-Voltage Protector launched by Wenzhou Jiangguang Electrical Technology Co., Ltd. powers on when it detects that the voltage is normal and stable, and trips in cases of over-voltage at 275V and under-voltage at 170V, providing effective protection for circuits and equipment
