[0002] A low voltage cabinet is a device used to distribute, control and protect the power system. It is usually composed of a metal box and internal electrical components such as circuit breakers, contactors, etc. The low voltage cabinet can manage the power supply and protect electrical equipment from electrical faults such as overload and short circuit. In the industrial, commercial and construction fields, low voltage cabinets are widely used in power distribution systems to ensure that electricity is safely and stably distributed to various electrical equipment and to ensure the normal operation of production and living electricity.

[0003] The existing low-voltage cabinet needs to be assembled on the base when in use. However, most of the existing low-voltage cabinets are fixed on the base by multiple sets of screws during the assembly process. External tools are required in the process of assembly and disassembly using screws. Multiple sets of screws need to be turned during assembly and disassembly. There are many operation steps and low work efficiency. Therefore, we propose a low-voltage cabinet that is easy to assemble. Utility Model Content
