Overview

The Mersen CNL300 is a specialized time-delay blade fuse designed for heavy-duty DC battery-powered equipment. Rated at 80V AC/DC and 300A, this fuse provides essential circuit protection for applications including forklift trucks, battery hand trucks, and motorized work platforms. Its 2.5kA interrupting rating ensures reliable fault protection in demanding industrial conditions. The CNL300 features a stud-mounted, bolt-in design for secure installation and long-lasting performance. A key benefit is the visual indicator, allowing quick status verification of fuse operation without disassembly. This fuse is part of Mersen's Forklift Truck and Battery Isolator fuse line, engineered specifically for heavy-duty DC loads up to 80V. Compatible with Mersen fuse blocks FTFH and FTFH-1, it prevents nuisance tripping during temporary overloads while maintaining protection against sustained faults. The CNL300 is part of Mersen's expanded line of forklift truck fuses, which includes ampere ratings from 10A to 800A and is designed for use in battery systems, hand trucks, and motorized platforms.
