The electrical wire connector made of the best flame-retardant insulating material Nylon PA66. With the advantages of long life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardant, it can effectively prevent electrical leakage. So the lever nuts are safer than traditional wire nuts The able connector Easy installation, no tool operation, plug and play. Each connector has independent shrapnel, different wires are managed separately, and different wire diameters can be safely connected. Built-in test points, no need to remove tape for electrical measurement. Technological innovations have replaced traditional electrical tape and braided butt connectors, reducing wiring time by more than 70%. The quick wire connectors are widely applied for motor, electrical control, power supply, home appliance, machinery and other electrical connections. Suitable for hard wire 0.08-4.0mm²/ AWG28-12, soft wire 0.08-2.5mm²/AWG28-14 Screw fixation: M3 screw mou
