Good security performance; : it is composed of of the best flame retardant nylon PA66 insulating material. It has the advantages of long service life, resistance to corrosion, resistance to aging, resistance to high voltage, insulation, flame retardant, etc., which can effectively prevent leakage. Therefore, the nuts with lever are more secure than traditional threaded nuts. High quality internal materials; : The internal shrapnel is made of copper, and the special surface coating is anti-oxidation, low resistivity. and better conductivity electric. The clamping technology at; spring is reliable and will not fall off. É that the clamping force can be automatically adjusted with the thickness of the conductor, the contact of the conductor is reliable and is not affected. through the installation process. Easy to install. use: easy to use; install, no tools required. Just plug and play, and you're done. Each node has an independent shrapnel, and different wires are managed separately, and different wire diameters can be safely connected. . Built-in test points, no need to remove tape for electrical testing. Technological innovation has reduced wiring time by more than 50%. Wide range of applications: widely used; in building wiring, such as controlling multiple lights via a switch. It is ideal for compact and complex applications. Convenience; : They are very suitable for detachable connections because no soldering is required. Suitable for 0.08 4mm² / 2812AWG. Faster and more reliable connection of any combination of strong, stranded and flexible copper wires. If you need to change other wires, just pull the little lever and remove and replace what you need, very convenient.
