Eaton has set a standard of excellence for polymer distribution cutouts with its Cooper Power series UltraSIL polymer-insulated interchangeable cutouts, now available in a loadbreak version. Our premium UltraSIL polymer-insulated cutout incorporates an industry recognized silicone rubber insulating material with superior hydrophobic qualities. Eaton offers the loadbreak Type LB cutouts in both polymer and porcelain designs, which provide reliable overcurrent protection for primary distribution circuits. Overcurrent protection safeguards an electric system from excessive current produced by abnormal conditions such as faults, line or equipment overloads, or equipment failures. Polymer and porcelain Type LB cutouts are ruggedly constructed and will provide full-range overcurrent protection from minimum melt of a given fuse link to the maximum nameplate interrupting current rating of the cutout.
