TB Wire Protector Terminal Blocks

Heyco TB Wire Protector Terminal Blocks are designed to securely connect solid or stranded wires without crimp terminals or soldering, thanks to an integrated wire protector flap that prevents conductor damage during installation. The screw-to-screw design ensures that both input and output wires are firmly fastened, enabling easy standardization of solid-wire cordsets across applications. These rugged terminal blocks come in a modern, low-profile form factor that saves space while maintaining a "dead front" design with no exposed metal parts for improved electrical safety. All models are rated for 300V (450V in Europe) and use galvanized steel screws and nickel- or tin-plated brass inserts for reliability and long-term performance. Heyco TB Wire Protector Terminal Blocks are constructed from nylon 6/6 materials and feature a UL 94V-2 flammability rating.
