The terminal box is made from high-quality cold-rolled steel and stainless steel. Its structure is designed for outdoor waterproofing, with protection levels that can reach IP54 or IP55 based on user requirements. This terminal box is suitable for various climate conditions and operational environments. The terminal box serves as an interface device for connecting construction lines, labeling branch circuits, and facilitating wiring and troubleshooting. In some cases, for ease of construction and debugging, certain specialized products, such as short-circuit isolators, can be installed inside the terminal box. The terminal itself is a component used for electrical connections, classified under connectors in industrial applications. The interior of the terminal box also includes a single-phase three-hole 220V, 16A power socket and a maintenance lighting fixture for user convenience during routine checks. Additionally, a transfer switch is designed to allow users to switch the heater inside the box between manual and automatic control modes as needed based on actual operational conditions. The primary functions of the terminal box are to connect and distribute cables, enhance circuit safety, and protect cables and connectors, making it an essential component in modern electrical installations, widely used in high-rise buildings. The JXF series distribution box is a distribution device designed and assembled based on the model, specifications, and quantity of components to fulfill various control functions. This product is widely used in industrial and civil construction, operating in power systems with a rated voltage of 380V or below and a frequency of 50Hz for power distribution, lighting distribution, and automation control. The JXF series features a closed structure, which can be surface-mounted on a wall or recessed into it. The box is made from bent and welded cold-rolled steel plate, with a surface treated through electrostatic spraying for aesthetics and protective performance. The box door and body are equipped with grounding screws connected by multi-stranded soft wire, ensuring good grounding protection. The product's outer casing has a protection rating of IP65 and complies with EC60439-1 standards.
