The 12kV VMV modular circuit breaker is the 4^th generation medium voltage embedded pole vacuum circuit breaker developed by our company. Of an optimized simple structure design, this modular safety switch enjoys an expanded mechanical life. And its modular spring mechanism is credited for a higher efficiency and reliable performances. Besides, to further promote its operating properties, this modular CB is equipped with a built-in closing spring charging lever.

Product Features of 12kV Modular Circuit Breaker
1. This 12kV modular electrical switch, the fourth generation of our 12kV vacuum circuit breaker, is a carefully designed and manufactured product.
2. This medium voltage modular CB enjoys an optimized drive system and a modular spring operation mechanism.
3. It employs the second generation embedded poles whose extremely low-resistance vacuum interrupter and main circuit are entirely sealed by the epoxy resin. Therefore, it enjoys a more reliable insulation property.
4. The built-in charging handles make it easier for you to carry and hardly to lose the modular vacuum circuit breaker.
5. It could operate smoothly in such extremely harsh environments as deserts in Mid-east, extremely cold areas in Siberia of Russia, and the plateau areas in western China.
6. This modular circuit breaker meets the GB1984 of China's state standard, DL403 of China's power industry standard, DIN VDE0670 of German standards, IEC62271-100 and IEC56 of IEC standards, as well as related standards of other developed industrial countries.
7. This 4th generation 12kV CB has passed the type tests of Guobiao standards (GB) and IEC standard, as well as the national appraisals.
8. Its mechanical endurance could be up to 60,000 operations.
9. The medium voltage VCB has been exported to over 26 countries all over the world.

Wide Application of 12kV Modular Circuit Breaker

Thanks to its advanced design and highly reliable performances, this modular circuit breaker could be used in such various fields as the power distributions, hydropower plants, wind power plants, thermal power plants, oil and gas industrials, offshore operations and urban infrastructure constructions. Moreover, it can run smoothly in some extremely harsh conditions, from freezing cold areas in Siberia of Russia, the Qinghai-Tibet Plateau in China, to the burning hot deserts in Middle East.

Modular Operating Mechanism

Another highlight of this vacuum circuit breaker is its modular operating mechanism. The tripping unit and closing unit of this spring mechanism are integrated as an independent module which, requiring a shorter production circle, is not only conductive to standard production, but also easy to maintain and replace. As all the modules are standard and universal for each type of this vacuum breaker, this modular electrical CB could benefit our customers by lowering their equipment management cost and maintenance.

Spring Operating Mechanism

Optimized Gear Drive System

Since we have improved the overall design of CB’s operating mechanism, this electrical circuit breaker enjoys a simple and compact structure and all the components it employs are standard parts that can be used universally. Furthermore, instead of the traditional chain-wheel drive system, this vacuum circuit breaker adopts a unique gear drive system which enables the breaker to run more smoothly and stably, and enjoy an expanded mechanical endurance.

Automatic Circuit Breaker Production Line

This medium voltage vacuum switch provided by our company are manufactured on the automatic circuit breaker production line which is designed and developed by our senior engineers according to our production needs and features of our products. Each production process on this automatic line is controlled and monitored by the computer. With this production line, our manufacturing capacity has been substantially promoted. Each year, we could provide 12,000 breakers to customers.

Complete Product Property Testing and Detection Equipment

Our company has several complete sets of mechanical property testing and detection equipment which is used to test the entire technical parameters of every breaker before the delivery. The strict test and detection we imposed on our products could effectively ensure a stable quality of each modular circuit breaker by avoiding the possible malfunctions that happens to it during its operation.

Additionally, in order to maker sure that all the circuit breakers enjoy a consistent good quality and meet the ISO9001: 2008 standards, each breaker we provide to you is manufactured by advanced production processes and would go through the conventional tests and inspections. And all the breakers would not be delivered unless the very responsible person submits a test report with his or her signature, a report that could ensure the product tractability and quality of the breakers.

Successful Application of 12kV Modular Circuit Breaker

As a professional medium voltage circuit breaker manufacturer and supplier, Minde, based on its great R&D capacity, could continuously provide more safe and reliable products to you. This vacuum circuit breaker, the 4^th generation of our 12kV vacuum protection switch, is an elaborately designed and manufactured product which has gain good reputations from customers both abroad and at home. The following picture shows that our modular CB has been applied in the AL-JOUF cement factory of Saudi Arabia.
