Eaton KQT Cable Limiter - 200 kAIC at 600 Vac
Part Number: KQT
Quick Summary
The Eaton KQT cable limiter protects feeders and equipment by interrupting faults in low-voltage power systems. Engineers often face nuisance trips, limited interrupt capacity, or slow protection when cable limiters fail to respond. RoHS compliant with a 200 kAIC at 600 Vac rating, plus Class H and Class K5 construction, ensure reliability. As part of the Bussmann series, it delivers fast, predictable fault isolation, reducing downtime and maintenance costs. This makes it ideal for panel builders, OEMs, and service teams seeking compliant, scalable protection. Its tubular end x offset bolted end and copper 10 AWG wire support straightforward installation in modern switchboards.

Eaton Specification Sheet - KQT
High interrupt rating and rugged construction deliver real business value. The 200 kAIC at 600 Vac capability means high-energy faults are interrupted before they cascade into equipment damage or downtime. This capability is critical in motor control centers and panel boards where downtime costs escalate quickly, and selective coordination reduces nuisance trips while maintaining safety. Class H and Class K5 designations provide protective performance and selective coordination, improving fault isolation in demanding environments and enabling more precise protection strategies in MCCs and machine lines. Copper #10 AWG wiring supports standard panel wiring practices, reducing inventory variety and simplifying retrofits in control cabinets and enclosure assemblies. The tubular end x offset bolted end configuration offers robust, field-ready connections for compact switchgear while the non-indicating status supports rugged operation in harsh environments. RoHS-compliant construction helps streamline regulatory approvals and sustainability goals for global deployments. Compatibility with Bussmann series catalogs and datasheets simplifies specification alignment during procurement and installation planning.
