Overview

The Mersen CP250A1-HS is a special purpose current-limiting device designed for quick fault clearing and isolation in service entrance and distribution runs. This Amp-Trap® cable protector is specifically engineered for 250 MCM aluminum cables and features heat-shrinkable (HS) tubing for field installation, ensuring robust insulation and protection. With a high interrupting rating of 200,000A, it effectively clears faults while allowing normal low cable overloads to be handled by standard protective devices. The CP250A1-HS is built with fiberglass bodies for dimensional stability in harsh environments and features crimp terminals with an included oxide inhibitor for aluminum cable. Its catalog number is stamped directly onto the terminal for permanent identification. This UL listed device (File E305297) is permitted by the National Electrical Code®, providing reliable protection for critical electrical infrastructure. Mersen CP cable protectors are rated for specific cable sizes and materials, offering tailored solutions for various applications. The heat shrinkable tubing option enhances its suitability for field installations requiring secure and protected connections.
