Overview

The Littelfuse LCC4 POWR-JAW clamps are precision-engineered to eliminate nuisance fuse openings and component aging caused by poor electrical contact in high-current fuse applications. These clamps apply consistent pressure to fuse clips via a high-temperature phenolic resin knob, ensuring stable contact resistance even in severe thermal conditions. Unlike standard clip designs that lose spring tension due to annealing, the POWR-JAW clamps maintain optimal clamping force, reducing heat generation at the fuse-clip interface. Designed for 600V systems with current ratings from 35-60A, the LCC4 clamps support both ferrule and blade fuse applications. The phenolic resin knob withstands extreme temperatures, making it ideal for industrial environments where reliability is critical. Installation requires only a simple twist of the knob, eliminating the need for tools and reducing downtime during maintenance. By preventing resistive heating and contact degradation, the LCC4 clamps extend the operational life of fuse protection systems while improving system efficiency. Common applications include motor control centers, panelboards, and industrial distribution equipment where consistent fuse performance is essential. The clamps are part of the POWR-JAW series, which is engineered to improve contact between fuse and clip, reducing unnecessary heat from poor contact and preventing premature aging of surrounding components. Key specifications include a 600V voltage rating, 35-60A current rating, and high-temperature phenolic resin construction. The clamps are sold individually and require a minimum of 1/8” clearance between the fuseblock barrier and fuse clip for proper installation. Seven sizes are available to match specific fuse requirements, ensuring compatibility with a wide range of fuse types and applications.
