4pcs Kv439 Lever-nut Wire Connector Set, 3 In 9 Out Conductor Compact Wire Connectors, Compact Connector Spring Terminal Block The product is shipped based on the color or size of the main image of the product page. Easy to install, it is no need operated by tools. Just plug and play, and then finished. Different wire are managed separately, different diameter can be safely connected. Built-in test point, electric test no need to remove tape. Instead of traditional electrical tape and twist-type electrical butt connectors, technological innovations reduce wiring time by more than 50%. They are ideal for removable connections because soldering does not need to occur. Suitable for copper wire size 0.084mm / 2812 AWG. Connect any combination of solid, stranded and flexible copper wire faster and more reliably. If you need to change other wires, just lift the small lever and pull out what you need and replace, very convenient. Made from the best flame retardant insulation material Nylon PA66. With the advantages of long service life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardant, it can effectively prevent electric leakage. So the lever nuts are safer than traditional metal nuts. The internal spring contact is copper material, special surface plating to prevent oxidation, low resistivity and better properties drivers. Spring clamp technology is reliable and does not fall off. Since the clamping force can be automatically adjusted with the thickness of the conductor, the contact of the conductor is reliable and is not affected by the installation technology. Widely Application: It is widely applied to building wiring, such as used to control multiple lights by one switch. It is ideal for compact and complex applications.
