Eaton KTK-R-12 Fuse - Class CC UL Listed 200 kAIC
Part Number: KTK-R-12
Quick Summary
KTK-R-12 fuse provides current-limiting fast-acting protection for industrial controls panels and machinery. Engineers often battle nuisance trips and unexpected downtime caused by short circuits, capacitor surges, or wiring faults. This fuse helps you achieve selective protection with a robust interrupt rating while preserving service to unaffected circuits. It carries RoHS compliance, CE marking, UL Listed status, and CSA certification, supporting global design approvals and supplier confidence. With a 12 A rating, 600 V rating, dual-element design, and a 200 kAIC interrupt capability, it aligns high-performance protection with compact installation requirements. Rejection-style ferrule ends and a small 1.5 in length simplify integration into standard control panel layouts, enabling scalable protection across multiple cabinets and machines while keeping maintenance straightforward.
