Feature → Business Impact → Application: The KTU-1100 is a Class L, fast-acting current-limiting fuse, delivering rapid fault interruption which minimizes arc flash energy and protects downstream equipment. This translates to reduced downtime, longer motor and drive life, and lower replacement costs in heavy-duty applications. Application-wise, it suits control cabinets and power distribution gear in manufacturing lines where high fault currents can occur but fast clearing is essential. Feature → Business Impact → Application: The fuse is bolt-mounted with ferrule design, enabling secure, vibration-resistant installation in harsh environments and simplifying field service. This reduces installation time and ensures repeatable performance in panel builds and retrofit projects. Feature → Business Impact → Application: Rated at 600 V with 1100 A capacity and 200 kAIC interrupt rating, it supports large motor starters, feeders, and power circuits while maintaining compliance with electrical safety standards. This provides predictable protection in machinery, packaging, and process lines. Feature → Business Impact → Application: RoHS compliant and CE marked, ensuring regulatory alignment for EU projects and green procurement programs, which can accelerate commissioning and audits. This enables procurement teams to standardize on a single fuse family across regional facilities. Feature → Business Impact → Application: The melamine glass tube and silver-plated end bells combine durability with reliable current interruption, reducing nuisance tripping and extending service intervals in high-energy environments such as presses, conveyors, and CNC systems.

FAQs
The KTU-1100 uses bolt mounting, designed for secure installation in standard Bussmann Class L fuse holders and power panels. Its ferrule design supports durable field connections, while the bolt mount simplifies retrofit and ensures reliable operation in vibration-prone environments.
Key ratings include a 1100 A amperage rating, 600 V voltage rating, and a 200 kAIC interrupt rating at 600 Vac. These specifications provide robust protection for high-current circuits, reducing fault energy and safeguarding upstream equipment.
Recommended for industrial control panels, motor drives, and power distribution cabinets where high fault currents may occur but fast clearing is essential. Its current-limiting design minimizes arc energy and protects downstream equipment in manufacturing, packaging, and process environments.
The fuse is RoHS compliant and CE marked, aligning with environmental and European market requirements. These certifications support regulatory compliance during installation, audits, and procurement in global facilities.
Its high interrupt rating and current-limiting action reduce arc energy and wear on system components, leading to less frequent replacements and shorter downtime. Durable construction plus easy bolt installation lowers service time during inspections and retrofits, improving overall equipment reliability and return on investment.
