Eaton KFH-A Cable Limiter - 200 kAIC at 600 Vac
Part Number: KFH-A
Quick Summary
The Eaton KFH-A cable limiter protects power distribution circuits in switchgear and panel installations. Engineers frequently contend with nuisance trips and cascading faults; this limiter provides reliable fault interruption with fast response. It is RoHS compliant and rated for 200 kAIC at 600 Vac, with copper 250 kcmil conductors for robust performance. For OEMs and service teams, installation is streamlined by a compression rod x tubular end design, while the compact footprint supports dense panel layouts. By delivering high interrupt capacity and regulatory compliance, the KFH-A helps minimize downtime, extend equipment life, and lower lifecycle costs in industrial electrical systems.

FAQs
The KFH-A uses a compression rod x tubular end connection, designed for straightforward field assembly. Ensure the copper cable is 250 kcmil and seating is secure to achieve the rated 200 kAIC at 600 Vac. Verify clearance and mounting orientation in the panel to maintain proper cooling and service access.
Yes, the KFH-A is specified for 250 kcmil copper conductors. Install the cable into the compression rod x tubular end so that the conductor is firmly captured, then torque or secure per manufacturer guidance to sustain the 200 kAIC interrupt rating. Proper seating minimizes contact resistance and heat buildup.
Ideal for main feeders and protection schemes in switchgear, panelboards, and power distribution assemblies. Its high interrupt rating, RoHS compliance, and copper 250 kcmil capability make it suitable for dense, high-energy environments where reliability and regulatory alignment are priorities.
The KFH-A is RoHS compliant, aligning with environmental and regulatory requirements for modern electrical components. While not listing additional certifications in the provided data, RoHS compliance ensures regulatory compatibility in most industrial and commercial installations.
The KFH-A delivers high fault-interruption capability with a non-indicating design that simplifies routine checks, reducing maintenance overhead. Its robust 200 kAIC rating and copper 250 kcmil conductors improve uptime, lower downtime-related costs, and extend equipment life in high-energy distribution networks.
