Amperage rating of 1600 A ensures protection for large feeders and high-load circuits, reducing the risk of catastrophic failure and enabling selective coordination. The 200 kAIC interrupt rating at 600 VAC provides robust fault current handling, improving uptime in environments with high fault currents and dense electrical networks. As a fast-acting current-limiting Class L fuse, it limits arc-flash energy and damage, enabling smaller downstream protection settings and potential savings on downstream devices. Physical ends are bolt-on blade-to-blade, simplifying panel integration and maintenance while supporting reliable bolted connections in tight enclosures. With a 3 in length, 3 in width, and 1.75 in height form factor, it fits standard protection blocks and supports quick retrofits. Special features include indicating options to speed maintenance, while CE and RoHS compliance cover regulatory expectations for global deployments. The fuse’s standard packaging and 1-piece configuration reduce installation time and risk of component mismatch, which translates to lower total cost of ownership over the equipment lifecycle.

FAQs
The KLU-1600 is designed for high-current feeders in industrial power distribution, including motor control centers, switchgear, and large distribution panels. Its 1600 A rating and current-limiting Class L design help prevent ductwork and equipment damage during short circuits, while enabling selective coordination with downstream protective devices to minimize downtime and maintenance costs.
The 200 kAIC interrupt rating at 600 VAC means the fuse can safely interrupt very high fault currents without sustained arcing or damage to surrounding equipment. This capability reduces the risk of cascading failures in heavily faulted systems and enables reliable protection for large feeders in demanding industrial environments.
Yes. The KLU-1600 uses bolt-on ends with bolted blade-to-blade connections, designed for secure mounting in standard protection blocks. This arrangement simplifies installation, improves contact integrity, and supports easy retrofits in existing enclosures without specialized adapters or tooling.
The fuse carries CE marking and RoHS compliance, indicating conformity with European performance, safety, and substance-use standards. These certifications help ensure regulatory acceptance across global markets and support responsible procurement and environmental responsibility for electrical protection upgrades.
Maintenance benefits stem from fast fault clearing, reduced downstream damage, and longer service life of protective gear. The indicating option aids status checks during routine inspections, while robust ratings limit unnecessary replacements. Over time, this translates to lower maintenance costs, reduced downtime, and a favorable return on investment in high-current distribution applications.
