Plastic junction boxes are widely used in the low-voltage electrical field, exhibiting features such as fire resistance, insulation, corrosion resistance, and acid and alkali resistance. The terminals inside the junction box are designed with a fixed structure, making them less prone to loosening and ensuring secure and stable wire connections.
SHQ3 series junction boxes are divided into two types: with knock-out holes and without knock-out holes. Customers can choose to have rubber plugs or knock-out holes according to their needs. The interior space of the junction box is spacious, and the installation of wires is simple and convenient, and it is also very easy to use.
