Overview

The Mersen CP500C7 is a specialized Amp-Trap® fuse designed as a current limiter for cable protection. This model is engineered to quickly clear and isolate faults, significantly enhancing the reliability of service entrance and distribution circuits. It functions as a current-limiting device with a robust 200,000A interrupting rating, ensuring safety during high fault conditions. Crucially, the CP500C7 is designed to accommodate minor cable overloads that are typically handled by standard protective devices, preventing unnecessary tripping and maintaining service continuity. This cable protector is rated for 500 MCM cable size and is suitable for copper (Cu) conductors. The straight blade to blade connection facilitates secure installation. For field installations, Mersen offers optional heat shrinkable (HS) tubing. When dealing with cables smaller than 4/0 AWG, Class J fuses can be considered as an alternative. The Mersen CP500C7 (SKU: CP500C7) is manufactured in the USA and adheres to UNSPSC code 39121606.
