The basics of NEMA terminal blocks.
NEMA terminal blocks are rated according to NEMA standards and are intended for use in circuits rated up to 1000 VAC. NEMA terminal blocks utilize a screw clamp mechanism, making them extremely reliable and able to withstand rougher conditions. You’ll find NEMA terminal blocks in heavy duty applications, and while they do take up more space than IEC terminal blocks, they are more capable in handling high current applications. However, rail sizes used for NEMA terminal blocks differ from manufacturer to manufacturer. NEMA terminal blocks can also be panel mounted.
The advantages of NEMA terminal blocks
NEMA terminal blocks are built with open construction which makes them easier to maintain, wire and configure. They are screw clamp terminal blocks, making them extremely tough and rugged, creating a reliable connection thanks to the high contact pressure between the conductor and conductor strip. Sectors that rely on NEMA terminal blocks include industrial, commercial, marine, and even railways. While they may offer less terminations per linear foot than IEC terminal blocks, they can still be more cost-effective in certain applications. NEMA terminal blocks can accommodate wires ranging from 0.34 mm2 to 4 mm2.
