MNS low-voltage withdrawable switchgear is a combination cabinet type assembled by factory using standard modules (FBA). This series of low-voltage withdrawable switchgear is suitable for power plants, substations, petrochemicals, metallurgical steel rolling, transportation and energy, light industry and textile enterprises, residential areas, high-rise buildings and other places. It is used for the conversion, distribution and control of electrical energy in power systems with AC 50-60HZ and rated working voltage of AC 660V and below.
Terms of Use
Surrounding air: The temperature should not exceed+40 ° C, not be lower than -5 ° C, and the average temperature within 24 hours should not exceed+35 ° C.
Atmospheric conditions: The air is clean, with a relative humidity not exceeding 50% at a maximum temperature of+40 ° C. Higher relative humidity is allowed at lower temperatures, such as 90% at+20 ° C, but temperature changes should be taken into account,
It is possible that condensation may occur accidentally.
The altitude shall not exceed 2000m.
If the above usage conditions cannot be met, it should be resolved through negotiation between the user and the manufacturer.
When this device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
Main Features
Compact design: able to accommodate more functional units in a smaller space.
Strong structural universality and flexible assembly. The C profile with a module of 25mm can meet the requirements of various structural forms, protection levels, and usage environments.
Adopting standard module design: It can form standard units for protection, operation, conversion, control, adjustment, measurement, indication, etc. Users can choose to assemble them according to their needs. More than 200 types of assembly components can be used to assemble different cabinet frame structures and form fixed partition or drawer units.
Safety: A large number of high-strength flame-retardant engineering plastic components are used to effectively enhance the protective and safety performance.
High technical performance: The main parameters have reached the contemporary international level.
Compressed site: With a high degree of industrialization, it can greatly compress the storage and transportation of prefabricated components.
Easy to assemble: No need for special complex tools.
Switch cabinet type
Power distribution cabinet (PC): EmaX, MT, 3WN, AH, ME series circuit breakers can be used.
Motor Control Center Cabinet (MCC): Assembled from large and small drawers, the main switches of each circuit adopt high breaking plastic shell circuit breakers or rotary load switches with fuses.
Power factor automatic compensation cabinet (with manual, automatic, and remote power factor compensation devices)
