Overview

The Mersen CP400C1 Amp-Trap fuse provides high-speed fault isolation for 400 MCM copper cable-to-cable applications at 600VAC, ensuring rapid response to overcurrent conditions. Designed as a current-limiting fuse, it delivers a 200,000A interrupting rating, enabling quick fault clearing while safely managing low cable overloads that standard protective devices may not address effectively. The fuse incorporates a phenolic insulator and a fiberglass body, providing dimensional stability and durability in harsh operating environments. It is rated exclusively for copper cables and supports a wide range of conductor sizes, from #2 AWG to 1000 MCM, offering flexibility for various installation requirements. The CP400C1 is part of Mersen's specialized CP Cable Protectors line, which includes both crimped and bolted connection options for service entrance and distribution runs, ensuring compatibility with different system configurations. Optional heat-shrinkable tubing or molded rubber boots are available for field installation, enhancing protection against environmental factors and simplifying the installation process. This fuse is engineered for reliability in critical power distribution systems where fast fault isolation is essential, making it a trusted solution for protecting high-capacity copper cable applications.
