    As a professional manufacturer of moulded case circuit breakers, Shanghai Great Wall has accumulated a lot of valuable experience in manufacturing and R & D, and conducted targeted research on the tripping fault of molded case circuit breakers. Now, the manufacturer of molded case circuit breakers will take you to analyze the reasons for tripping of molded case circuit breakers.

    I. overloading.

    Due to the increasing use of high-power electrical equipment in factories or families, it brings a certain burden to molded case circuit breakers. When too many high-power electrical equipment are used at the same time, exceeding the rated current of the molded case circuit breaker will cause the tripping of the molded case circuit breaker. Therefore, the manufacturer of the molded case circuit breaker - great wall switch, recommends that if there are too many electrical equipment, you can replace the molded case circuit breaker with larger specifications, or reduce the load current, and open a few electrical equipment less.

    Two. Short circuit.

    The short circuit phenomenon of the power line refers to that the circuit or a part of the circuit is short circuited, for example, the load and the two ends of the power supply are connected by wires. Short circuit will burn the equipment on the line and even cause safety accidents. In case of short circuit fault, molded case circuit breaker will act quickly and trip automatically to ensure the safety of power line or electrical equipment.

    Three. Leakage.

    If the insulating layer of the outer layer of the wire is damaged, it will cause current leakage. In case of leakage fault of power line, molded case circuit breaker will trip automatically to avoid damage of power supply and equipment. The best way to detect leakage is to contact the electrified body with a pen. If neon bubble lights up, it will go out immediately. It is proved that the electrified body carries static electricity. If it lights up for a long time, it is undoubtedly leakage.
