    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.

    Screw Clamp Terminal Blocks

    Screw Clamp Terminal Blocks

    The mechanism in screw clamp terminal blocks provide an extremely secure connection between the conductors and conductor strips. As one of the most widely used terminal blocks in the industry, the reliable connection and steel screw clamp is a popular choice in marine applications, solar applications, railways, and more.

    Power Distribution Blocks

    Power distribution blocks are used for branch circuit applications. They can be either panel mounted or DIN rail mounted with high short circuit ratings. They are also used to take in primary power and distribute it throughout secondary circuits. Applications including manufacturing, food processing and building automation.

    NEMA Terminal Blocks

    NEMA Terminal Blocks

    NEMA terminal blocks are screw clamp terminal blocks that are commonly used in heavy duty applications. They are larger in size compared to IEC terminal blocks, but they are better equipped to handle high current applications. NEMA terminal blocks are open-style terminal blocks which make for easier wiring.

    IEC Terminal Blocks

    IEC Terminal Blocks

    Available with either screw clamp or spring clamp mechanisms, IEC terminal blocks are high performance performance terminal blocks. They are DIN rail mounted terminal blocks and are known for their ease of installation and high applicability. Since DIN rail sizing is standardized, IEC terminal blocks are compatible across manufacturers.
