What is the difference between ABB s MD190 and MNS cabinets?

MD190 and MNS cabinet when the switch capacity is in the range of 6300 800A, the two forms are basically the same, the difference is that below 630A, MD190 adopts the best segmentation form, the advantages are compact structure, less investment cost, small footprint; The disadvantage is that it is small, and too many control elements cannot be installed in the circuit. MNS adopts the extraction type, the structure is relatively fixed, and the bucket has a large space to install a little control element; The disadvantage is that it occupies a large area and has a lot of investment costs.

MD190 is generally used in the occasion of many small-capacity switches and relatively simple control requirements, otherwise, only MNS switchgear can be selected.

To put it simply: combined type - MD190, mainly used outdoors, wiring method is your own choice, flexible, multi-purpose, such as reactive power compensation, Sino-British air conditioning control, etc.

Simple --- MNS, which is mainly used indoors, is used for community and home terminal power distribution, which is generally installed with a micro circuit breaker, which is not as complex as MD190, and each user must have one.

Simple --- MNS, which is mainly used indoors, is used for community and home terminal power distribution, which is generally installed with micro circuit breakers, not as complex as MD190, each user must be equipped with one Classmates, are you kidding MNS Many of them are used for power distribution in large enterprises, and what else is generally micro-disconnected, have you ever seen a micro-disconnection of 5000A.

Combined low-voltage switchgear (MD190).

The high-strength profile makes the cabinet stronger.

Fixed divider and drawer type.

Compact arrangement, space saving, cost saving.

The combination is flexible and versatile.

Low-voltage switchgear (MNS).

Compact and space-saving.

The cabinets can be arranged back to back.

The distribution circuit is arranged economically.

The equipment has high operational continuity and reliability.

ABB MD190 (HONOR) "Anya" combined switchgear and MNS switchgear is a new generation of products developed by ABB in production and practice, according to 190mm as a basic module to meet the requirements of low-voltage system from the main switchgear to the minimum distribution cabinet and program control cabinet.

Electrical information in the School of Electronics, a total of 4 majors, automation, electronic information engineering, electrical engineering and automation, electronic information science and technology, one of them in the sophomore year Chongqing University of Technology School of Electronic Information and Automation, as one of the main secondary engineering colleges, after years of construction and development, has formed a reasonable structure and strong ability of the faculty. There are 77 full-time teachers. Among them, there are 13 professors, 34 associate professors, 20 doctors, and 45 masters, and 61% of the faculty have senior titles such as professors and associate professors, and 84% have doctors and masters.

At present, there are two master's programs in "Test and Measurement Technology and Instruments" and "Signal and Information" processing, as well as five undergraduate majors, including automation, electronic information engineering, measurement and control technology and instruments, electrical engineering and automation, and electronic information science and technology. The faculty of the college has rich experience in teaching, scientific research and engineering practice, has a wide range of scientific research topics, and has achieved rich scientific research results. At present, the college has a key discipline in Chongqing, a key discipline at the school level, and a group of academic leaders, reserve discipline leaders and backbone teachers in Chongqing.

Years of development have also enabled the college to form a good teaching conditions and practical teaching environment, and cultivate students with a solid theoretical foundation, considerable ability to analyze and solve problems, and a certain ability to innovate. The students of the college actively participate in extracurricular scientific and technological activities, pay attention to the cultivation of practical practical ability and comprehensive quality, and have won many national awards in the previous national college students' "Challenge Cup" extracurricular science and technology activity competition, the national college student electronic design competition, and the national college student mathematical modeling competition.

First, second, third prizes and provincial and ministerial awards. Graduates are welcomed by employers for adapting to the needs of society.
