FAQs
Yes. The KTK-R-7 uses ferrule-end x ferrule-end connections designed for Bussmann Series Class CC devices, simplifying installation in standard control panels and distribution gear. Its 1.5 in length and compact 0.41 in dimensions align with common DIN-rail and cabinet layouts, enabling quick retrofits and consistent terminations in new builds.
The dual-element current-limiting design rapidly interrupts fault currents, limiting peak let-through energy and reducing conductor heating and arc duration. With a 200 kAIC rating, it maintains dependable protection during high-energy faults, while providing selective coordination with upstream devices to minimize collateral outages in complex 600 V distribution networks.
KTK-R-7 is well-suited for industrial controls panels, street and general lighting, capacitors, and distribution networks in manufacturing plants and infrastructure projects. Its 7 A rating and 600 V capability cover small control circuits and auxiliary loads, while UL Listed and CSA Certified status supports compliance in multinational facilities and safety programs.
KTK-R-7 meets RoHS compliance, CE marking, UL Listed, and CSA certification. These approvals support regulatory compliance, facilitate cross-border procurement, and help simplify vendor qualification processes, especially in environments with strict safety, environmental, and reliability requirements.
Leverage the time-current curve guidance from Eaton datasheets to optimize replacement timing and avoid nuisance trips. Stock ferrule-end fuses in standard packs (10 per package) for rapid field swaps, perform periodic inspections of panel wiring, and document fault events to tune protection settings. These steps reduce downtime and extend equipment life, improving total cost of ownership.
