    Terminal Blocks

    Distributing power while optimizing your panel space.

    Used to distribute power and connect wires to one another, a terminal block is a modular device composed of an insulated body, and a clamp or screws to mount the terminal blocks. The wires are attached via screws or clamps and allow several circuits to be connected to another circuit. Terminal blocks, also referred to as terminal strips or terminal bars, help centralize your wiring while protecting against short circuits as well as optimizing panel space and preventing wire splicing which can be potential fire hazards. They also allow you to better maintain and control complex circuit systems.

    A control panel essential.

    As wiring systems become more and more complex, terminal blocks are required throughout commercial and industrial sectors. You’ll find NEMA terminal blocks and IEC terminal blocks in control panels across all applications where automation is required. Terminal blocks are extremely flexible and modular. They can be easily mounted onto DIN rail and additional terminal blocks can be added or moved within the control panel without disrupting other components. Their insulating body, usually made of some variation of thermoplastic, provide additional protection to both the operator and maintenance workers.
