    IEC Terminal Blocks

    Types of IEC terminal blocks.

    IEC terminal blocks are designed and rated according to IEC standards. IEC terminal blocks are used worldwide. Whether you need a ground terminal block, a feed through terminal block or a plug in terminal block, all of these can be designed in accordance with IEC standards. IEC terminal blocks can utilize either a screw clamp or a spring clamp mechanism. Both screw clamp and spring clamp terminal blocks provide secure and reliable connections, while spring clamps use an extra holding mechanism that can withstand vibration.

    High precision. High performance.

    Some electrical devices you choose based on system requirements and some you choose based on preferences. Choosing an IEC terminal block is a matter of preference, but it does have many advantages as well. IEC terminal blocks are universally recognized, and the majority of terminal blocks used in the United States of America are IEC terminal blocks. IEC terminal blocks are DIN rail mounted and are easier to install than NEMA terminal blocks while offering more terminations per linear foot. IEC terminal blocks can accommodate wires between 0.5 mm2 to 120 mm2 in size. Current ratings for IEC terminal blocks range from 20A to 232A
