overview
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(6o) Hz and a rated working voltage of 66oV 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,land the international standard IEC439. The switchgear can be configured into different schemes for cabinet frame structures and Idrawer units. It uses high-strength flame-retardant engineering plastic components, which effectively enhance safety protection
Iperformance. 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 laluminum-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 Ibrackets, 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.
