Set screw contacts remove the need to solder the cable into the contacts. The cable is secured using two preinstalled bronze Allen head set screws. These contacts are often used for on-site cable installations and they maintain all the standard features and carry the same amp rating as the solder contacts.
Set screw contacts reduce the installation time of couplers and the tools needed for the installation. All set screw contacts have two solid bronze set screws to increase contact pressure and provide maximum conductivity. The contacts are drilled to match the cable being used and the setscrews are also sized based on the cable, guaranteeing proper clamping. Solder-less setscrew design includes all phase, ground, and ground check contacts.
