Nylon insulated spade terminals are used where an insulated barrel and a positive insulation grip are necessary or desirable. Insulation is securely molded onto the barrel and is flared for easier wire insertion. Allows for an excellent mechanical crimp and wire strain relief. Industry standard color-coding indicates wire range. Rated to 600 volts. Terminal works best when double-crimped - once on the wire, and a second time over the insulation of the wire.
