MNS low voltage switchgear (hereinafter referred to as the equipment) is the basic design and development of imported switchgear products. Applicable to ac 50 (60) Hz rated working voltage of 660V and below system, for power generation, transmission, distribution, power conversion and power consumption control equipment. This device can be composed of cabinet frame structure and drawer unit of different schemes, adopting high-strength flame-retardant engineering plastic components, effectively enhancing the protection and safety performance, drawer unit has the characteristics of small size, strong function, high interchangeability, convenient replacement and maintenance, reliable contact and so on.
The basic cabinet frame of the device is a combined structure of c-shaped materials. All the structural parts of the cabinet frame are processed by zinc plating or made of aluminum and zinc coated plates. By tapping screw 8.8 hexagonal screw fastening connection each other into the basic framework, and the need to change according to the plan, combined with the corresponding door, sealing plate, diaphragm, mounting bracket and busbar, functional units and other components, form a complete unit, parts plant size, the size of the compartment, a modular (modulus E = 25 mm). Cabinet protection grade: IP3X-IP4X.
