MCCB industrial development

Currently, a large current MCCB forward direction, energy storage and hand-operated institutions electrically operated interchangeably, can significantly reduce the thickness of the product operating agencies charged narrow thickness distribution cabinets, improve short-circuit breaking targets, with double break Products matching high breaking basic indicators, improve short-resistant indicators and selective tripping reliability.
Now the market has seen a smaller, cost-effective molded case circuit breakers, circuit breaker saves production costs that reduce the thickness of the product, using the range has expanded a lot. In addition, reducing the number of parts, so that it can simplify the shape of a semi-automated mass production.
With improved production techniques, molded case circuit breaker rated current smaller, there has emerged 0.1 ~ 25A products. Technical indicators are more advanced, various properties are improved, particularly shockproof performance. In the development process, researchers, more modular product structure, miniaturization, integration, and more compact structure, the combination of program flexible assembly is also more convenient. In addition, the product can also install the soft starter, intelligent detectors and so on.
And ACB ACB as MCCB products derived DC-specific products, distributed photovoltaic grid-specific products and reclosing earth leakage circuit breaker performance has been further mcb circuit breaker improved. Special products derived DC operating voltage has been increased to 1000V or even higher, can be used in photovoltaic power generation, electric vehicle charging equipment, emergency power and other occasions; thermal-magnetic protection accuracy is also improved; isolation switch AC and DC common. Derived distributed photovoltaic grid-specific products tended to increase the resistance to heat, salt spray, UV and other harsh environments, and enhance key components strength and corrosion resistance, improve institutions and conducting system reliability, the smallest step size may be less than equal 1S. Derived  air circuit breaker earth leakage circuit breaker to increase the scope of application, for example, can be used for rural power grids.
Of course, these trends MCCB also requires relevant technical performance can be achieved, for example, contact interrupter system technology; completely selective with technology; DC critical current breaking technology; precision miniaturization mutual technical; motor protection circuit breaker mechanism modular technology; industrial production technology; DC current detection and protection technology; conductive loop heating and cooling technology.
MCCB as a low pressure in the important industrial electrical products, to improve and enhance its performance will further protect the safety of electrical workers, helping to reduce electrical accidents.
