Miniature circuit breakers are mainly used to protect the circuit from overload and short circuit. It can quickly cut off the circuit to protect the safety of electrical equipment and personnel, and is widely used in residential, commercial and industrial fields.

 

 

Scope of application

The miniature circuit breaker is a commonly used circuit protection device, which is mainly used for overload, short circuit protection and circuit breaking of low voltage circuits. It has the characteristics of small size, strong breaking capacity, long service life, reliable operation, etc. It is widely used in household appliances, computer equipment, communication equipment, automation equipment and other fields.

Miniature circuit breakers usually adopt a heat-responsive electromagnetic structure. When in use, they only need to be installed on the circuit. When the circuit is overloaded or short-circuited, it will automatically disconnect the circuit to protect the safety of electrical equipment and personnel. In addition, the miniature circuit breaker also has the characteristics of preventing arc tripping, repeated starting, and overload refusal, which can improve the stability and reliability of the circuit.

At present, there are many types of miniature circuit breakers on the market, and the common ones are air type, liquid type, gas type, etc. You can choose the appropriate product according to the application occasion and demand. At the same time, when consumers purchase miniature circuit breakers, they should also make correct choices based on the rated current, rated voltage, number of poles and other parameters of the circuit to ensure that the product can meet actual needs and ensure the safe and stable operation of the circuit.

The miniature circuit breaker has the characteristics of reliable structural performance, high breaking capacity, beautiful and compact appearance, etc. The shell and main components are made of impact-resistant and highly flame-retardant materials. It is suitable for places with AC 50Hz or 60Hz, rated working voltage of 400V and below, and rated current of 6A to 63A. It is mainly used for overload, short circuit and leakage protection of lighting, distribution lines and equipment of office buildings, residences and similar buildings, and can also be used for infrequent conversion of lines under normal conditions.
