Overview

The Mersen 2CL500BF is a specialized current-limiting fuse designed for rapid fault isolation in service entrance and distribution runs. Rated at 250VAC with a high interrupting rating of 200,000A, this cable protector ensures enhanced system reliability. It is engineered to accommodate 500 MCM copper or aluminum cabling, offering versatility for various installations. The 2CL500BF features a blade to offset bus termination, facilitating secure and efficient connections. Its design allows it to carry low cable overloads, which are managed by standard protective devices, preventing unnecessary tripping. Mersen's 2CL series cable protectors are constructed with fiberglass bodies for dimensional stability in challenging environments, and the catalog number is permanently stamped into the terminal for easy identification. This product is crucial for applications requiring quick fault clearing and protection of electrical infrastructure. Specifically, this fuse is part of the Mersen Offset Blade fuse-links series, designed for gM and gG applications. It is compatible with fuse-holders for Offset Blade & Central Bolted Tag Fuse-links, such as the Mersen BFB type, which features front back (busbar) stud connection. The 2CL500BF is manufactured in the US.
