Easy to install, no tools needed. Just plug and play, and you're done. Different wires are handled separately, allowing for safe connection of different diameters. An integrated test point allows for electrical testing without removing the tape. Technical innovations reduce wiring time by over 50%. They are ideal for movable connections as soldering is not necessary. Suitable for copper wires from 0.08 to 4 mm² / 28 to 12 AWG. Connect any combination of solid, stranded, and flexible copper wires faster and more reliably. If you need to change wires, simply lift the small lever, remove the desired wire, and replace it – very convenient. Made from the best flame-retardant insulating material, Nylon PA66. With the advantages of long life, corrosion resistance, aging resistance, high-pressure resistance, insulation, and flame retardancy, it can effectively prevent electrical leakage. Lever nuts are therefore safer than traditional metal nuts. The internal spring contact is made of copper with a special surface coating to prevent oxidation, resulting in low resistivity and improved conductivity. The spring-loaded clamping technology is reliable and prevents loosening. Since the clamping force can be automatically adjusted according to the conductor thickness, the conductor contact is reliable and unaffected by the installation method. Wide range of applications: It is widely used in building wiring, for example, to control multiple lights with a single switch. It is ideal for compact and complex applications.
