GCS and MNS are both draw-out switchgear, which are characterized by independent isolation and replacement of each outlet circuit, convenient maintenance and high reliability. There are many outlet circuits, which occupy less space. Suitable for places where socket switches are frequently operated and switches and accessories are frequently maintained, such as motor control and contactor maintenance.
The drawer structure of GCK is too simple, with no position indication and poor reliability. MNS is a patented product of ABB. The real MNS is only produced by Xiamen ABB low-voltage factory, and the price is extremely high, with an average of 654.38+ 10,000. However, the manufacturing process is excellent, and the quality of the accessories used is first-class, which is recommended by rich car owners.
For places where the building area of the distribution room is high, but the outlet switches are not frequently operated, and the switches and accessories do not need to be maintained, such as high-rise buildings such as office buildings or exhibition halls, conference centers, hotels and other places with high requirements for power supply reliability, it is recommended to adopt fixed split switchgear and plug-in molded case circuit breakers, such as SIKUS of Siemens, Prisma of Schneider Electric Company and ArTu of ABB Company. These cabinets are authorized by domestic manufacturers. The price is about 30% higher than that of GCS plus foreign brand circuit breakers, but it avoids the failure caused by the quality problem of drawer plug-ins (the main problem of drawer type in China is drawer quality problem), and has the same advantages as drawer type cabinets.
