the industry ceiling and r & d investment are low, and there are doubts about the growth of ipo of electric appliances in the future2020年，未来电器塑壳断路器附件收入为1.34亿元、框架断路器附件收入为8163万元；而在当期，未来电器塑壳断路器附件市场份额已达到了61.57%；框架断路器附件有多个细分品类，但未来电器多个框架断路器附件细分品类的市场份额已超过了10%。

big data forecast and analysis of china's low voltage electrical appliance industry market scale and product output in 2021 (figure)数据显示，我国低压电器市场规模从2016年的627亿元增长至2020年的862亿元，2020年较2019年增长52亿元，同比增长6.4%。预计2025年我国低压电器市场规模将达1240亿元。

Classification of Molded Case Circuit Breakers and Related ParametersAt present, Hangkai Electric Appliances (Shanghai) Co., Ltd. produces three types of plastic shell vacuum circuit breakers: distribution type, motor protection type, household and similar places.

knowledge introduction of small molded case circuit breaker小型断路器由固定和移动的交流接触器组成,交流接触器与传输线相连.金属材料或载流部件由电解铜或银铝合金制成,这是取决于隔离开关的额定电流.

what is the difference between molded case circuit breaker and leakage circuit breakercircuit breaker is a common product in our life. it is an electrical appliance that plays the role of on-off, control or protection in the circuit system. there are many types of circuit breakers, among which plastic case circuit breaker and leakage circuit breaker are quite common. here's the difference between them

what are the details of purchasing molded case circuit breakers

causes of faults in molded case circuit breakersactive and static contacts, auxiliary contacts, coils, short circuit rings, arc extinguishing covers and other components of low-voltage plastic case circuit breakers are liable to malfunction. when the equipment fails to trip, it can not be simply closed. it is necessary to check the appearance, arc extinguishing cover and other components for burnout. if so, it is necessary to remove the fault parts for inspection, repair or replacement, and wipe off the stains. here are some common breakdowns of circuit breakers and their solutions

Selection and Installation of Molded Case Circuit Breaker1. Application place and selection principle of plastic case circuit breaker: 1. High temperature places: ironmaking, casting, boiler room and other places, should choose the pure electromagnetic type (but not too high) which is not affected by temperature. For thermodynamic-electromagnetic type, when the temperature is between 40 60 C, it should be used to reduce capacity, and the temperature above 60 can not be used.

daily maintenance method of molded case circuit breakerenvironmental plastic case circuit breaker is mainly used to distribute electric energy and protect power lines and power supply equipment from overload, short circuit, undervoltage and other faults. equipment maintenance regulation is the requirement and regulation of daily maintenance of equipment. persisting in the implementation of equipment maintenance regulation can prolong the service life of equipment and ensure safe and comfortable work.

how to avoid wire head faults with contactors in molded case circuit breakerswhen using circuit breakers, contactors and circuit breakers are often connected but not electrified. if they are used without testing, the circuit will fail. many people suspect that the reason is that the product is out of order, in fact, because we have problems in the way of wiring, resulting in the absence of phase or short circuit between products. this paper introduces the correct wiring mode of circuit breaker and contactor.

development space of molded case circuit breakers in chinain recent years, the development momentum of electric industry in our country is rapid, forming a certain scale and perfect industrial chain, the production level of products has been greatly improved, and the quality of products has also been improved.

what are the characteristics of plastic case circuit breakerplastic case circuit breaker is also called device circuit breaker. all parts are sealed in plastic case, auxiliary contacts, undervoltage trippers and shunt trippers are modularized. because of its compact structure, the plastic case circuit breaker can hardly be repaired.
