Overview

The ABB FPW14 Insulation Piercing Washer (SKU: FPW14) is a specialized component designed for electrical connections where insulation needs to be penetrated. Manufactured by ABB - Installation Products, this washer facilitates secure and reliable electrical contact. Its construction features a copper alloy body, ensuring good conductivity, and is finished with tin plating for enhanced corrosion resistance and solderability. The outer diameter measures 17.3mm (0.68 inches), and the inner diameter is 6.9mm (0.27 inches), making it suitable for a 1/4 inch stud size. This precise sizing is critical for proper fitment and function in electrical assembly. The insulation piercing design allows the washer to create a direct electrical path through insulation layers, eliminating the need for stripping in certain applications. This method can streamline installation processes and maintain the integrity of surrounding insulation. The UNSPSC code for this product is 31161807. Applications for this type of washer are typically found in electrical distribution systems, control panels, and power connection assemblies where reliable piercing of conductor insulation is required. The material composition and plating are chosen to withstand typical environmental conditions encountered in industrial electrical installations.
