The MNS type low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) is an advanced low-voltage switchgear designed and improved based on the MNS series low-voltage switchgear abroad to meet the needs of the development of the power industry. It can be widely used in various low-voltage distribution systems such as power plants, substations, industrial and mining enterprises, buildings and hotels, and municipal construction.

1.The frame of the M NS type low-voltage switchgear is a modular structure, with the basic skeleton assembled from C-shaped steel. All structural components of the cabinet frame have been galvanized and firmly connected to form the basic cabinet frame using self tapping locking screws or 8.8 grade hexagonal bolts. In addition, corresponding components such as doors, partitions, installation brackets, and busbar functional units have been assembled to form a complete switchgear. The internal dimensions, component dimensions, and compartment dimensions of the switchgear vary according to modularization (E=25mm).

2.Each cabinet of the MNS type combination low-voltage switchgear is divided into three compartments, namely the horizontal busbar compartment (at the back of the cabinet), the drawer compartment (at the front of the cabinet), and the cable compartment (at the bottom or right side of the cabinet). The rooms are separated from each other by steel plates or high-strength flame-retardant plastic functional boards, and there are metal plates with ventilation holes between the upper and lower drawers to effectively prevent accidents caused by arcing or short circuits between busbars and other circuits due to faults in switch components.

3.The structural design of the M NS type low-voltage switchgear can meet the requirements of various incoming and outgoing line schemes: upper inlet and upper outlet, upper inlet and lower outlet, lower inlet and upper outlet, and lower inlet and lower outlet.

4.The structural components have strong universality and flexible assembly, with E=25mm as the modulus. The structure and pull-out units can be combined arbitrarily to meet the needs of system design.

5.The mechanical interlocking mechanism of various sizes of drawers complies with standard regulations, with three obvious positions for connection, testing, and separation, ensuring safety and reliability.

6.Adopting standard module design: It can form standard units for protection, operation, conversion, control, adjustment, measurement, indication, etc., and can be assembled according to requirements.

7.Highly standardized and universal, easy to assemble. Has reliable quality assurance.
