All-weather, super "longevity"! How can a few "brushes" be called universal circuit breakers

All-weather, super "longevity"! How can a few "brushes" be called universal circuit breakers


Today, new energy photovoltaic power stations are springing up all over the world, high-rises with "central nerve" are standing in cities, and new energy vehicles that can drive themselves are running on highways... . Our lives are accelerating to embrace an electrified, digital, low-carbon future. At the same time, smart city, smart power grid, smart industry, intelligent perception and other new terms that sound "smart" are also constantly refresh, "intelligent" has penetrated into all aspects of today's society, putting forward new requirements and challenges to the power distribution network.

All-weather, super "longevity"! How can a few "brushes" be called universal circuit breakers

Focusing on the electrical industry, Chint has researched and developed many "fist products" with leading market share in more than 30 years of "business" history. Among them, Chint's all kinds of universal circuit breakers will leave a heavy pen.

All-weather, super "longevity"! How can a few "brushes" be called universal circuit breakers


Universal circuit breakers, used as primary distribution protection elements, are generally used near transformers or at the very front end of lines, such as the main circuit control room or distribution room of a whole building, where short circuit current is much greater than that of secondary and end lines. Compared with terminal distribution components, the universal circuit breaker itself has higher technical requirements; And, its use of a wide range of industries, multiple application occasions, the reliability of the product requirements are also part of the stringent.


Today's new, is the power distribution tool in the series of Zhengtai Kunlun - a good ability of NXA series universal circuit breaker, fearless harsh environment, with industry-leading limit short circuit breaking ability...... To create high reliability, high quality, more efficient, more safe distribution system for users.


This Chint Kunlun family member, listed at the beginning, with high reliability to win the favor of many industry customers. Footprint in many fields, through a number of industry application demonstration, showing its deep "internal merit" and strong strength.


Top 10 Controller Technologies

With the wide application of intelligent universal circuit breaker in low-voltage distribution system, especially in the field of smart power grid distribution protection, its quality directly affects the reliability of distribution network and determines the market position of products to a certain extent. As the core component of intelligent universal circuit breaker, the controller is the key factor to determine the quality of products. NXA series universal circuit breaker fully improve control technology, hard practice ten "killer", strong guarantee product performance:

IT System Applicability

In some special scenes and devices, there are high requirements for uninterrupted power supply and electrical safety. Usually, TN or TT system is not used for power distribution, but 525V IT system is needed. This puts forward unique application requirements for universal circuit breaker products. Zhengtai kunlun series universal circuit breaker congeals the intellectual crystallization of many research and development "siege lion" and "program ape", this product is fully applicable to this kind of IT system under 525V, expanding the application range.

Adaptability Skills

The universal circuit breaker used as the main switch of the primary distribution system is generally installed in the complete cabinet body. The operating environment varies greatly from the cold climate in the north to the hot and humid climate in the south. Whether it is the shore power system outdoor sealed distribution cabinet along the coast, or the underground distribution room in residential areas, it can also be seen in a variety of application scenarios...... Diversified use conditions of the product itself adaptability requirements are very high, the need for circuit breakers to be able to operate reliably in a variety of harsh environments.


NXA universal circuit breaker operating temperature range from -45℃ to +70℃, can resist heat, humidity, salt spray and other harsh operating conditions, to ensure the long-term reliable operation of circuit breaker in harsh environment.


In addition, NXA universal circuit breaker "universal" is also reflected in the complete specifications, the controller function is perfect, electrical performance is strong, so strong "gravity", you get it?


In recent years, Chint has devoted itself to product innovation and intelligent upgrading in the field of power distribution, from product research and development, system integration to complete service, enabling electrical systems of all industries. In the future, it will continue to bring efficient and reliable life-cycle services to industry customers, comprehensively optimize customer value experience, and help accelerate the electrification and intelligent development process of the economy and society. Are you ready for the next generation of innovation in power distribution?
