The MNS series low-voltage switchgear assembly (the”switchgear”)is a product designed and developed based on imported switchgear products.It is applicable to systems with an AC frequency of 50(60)Hz and a rated working voltage of 660V or less, and is used for the control of power generation,transmission,distribution,conversion,and consumption equipment.It complies with GB7251-1 Low-Voltage Switchgear and Controlgear Assemblies,JB/T9661 Low-Voltage Drawable Switchgear Assemblies, and the international standard IEC439.The switchgear can be configured into ifferent schemes for cabinet frame structures and drawer units.It uses high-strength flame-retardant engineering plastic components,which effectively enhance safety protection performance.The drawer units are compact,powerful,highly interchangeable,and easy to replace and maintain,and have reliable contact.
Structural Features
The basic cabinet frame is a C-profile modular structure,and all the structural parts of the frame are either galvanized or made of aluminum-zinc-coated plates.They are fastened and connected to each other into a basic frame by self-tapping locking screws and grade 8.8 hexagon screws.Then,subject to the scheme changes,corresponding doors,sealing plates,partitions,mounting brackets,as well as components such as busbars and function units are added to form a complete device.The dimensions of the components and compartments inside the device are modularized (the modular unit E=25mm).The IP rating of the cabinet body is IP3X-IP4X.
