The 2201.0 is an industry-standard insulated ferrule designed for reliable electrical connections when terminating stranded flexible wire in terminal blocks, circuit breakers, and other control devices. It features a polypropylene sleeve and tin-plated copper tube construction, with color-coded identification by conductor size for convenient selection. The ferrule prevents conductor breakage due to bending, wire stress, or vibration while facilitating smooth wire insertion into terminal clamps. It meets CSA Std C22.2 No. 65-93 and 188-M1983, as well as ANSI/UL Std No. 486A and 486C standards. This ferrule is ideal for industrial control applications, electrical installations, and any scenario requiring secure wire termination with minimal conductor damage.
