Overview

The Mersen CNN40DIN (SKU: CNN40DIN) is a 40A forklift truck fuse designed for reliable DC circuit protection in heavy-duty battery-powered equipment. This fuse is suitable for applications including forklifts, hand trucks, and motorized work platforms, as well as other industrial DC systems. It operates at 130V AC or 80V DC and features a rugged, stud-mounted bolt-in design for enhanced durability in harsh environments. The flat CNN style blades ensure space-saving installation and provide visual 'see-thru' indication for quick confirmation of fuse operation. Rated for 40A continuous current, the CNN40DIN meets DIN 43560 fuse dimensions and is UL recognized for compatibility with SFBT fuse bases. Its compact form factor and visual fault indication are critical for applications where space is limited and rapid diagnosis is essential. The bolt-in mounting mechanism guarantees secure connections, even under the vibration typical of material handling equipment. This fuse offers a 2.5kA interrupting rating for both AC and DC applications.
