FAQs
The KPF cable limiter is a high-current protection device designed to limit fault currents in medium-to-large power distribution circuits. It accommodates Cu or Al conductors up to #4/0 AWG, rated at 600 V with a 200 kAIC interrupt capacity, making it suitable for switchgear, panels, and feeder protection in industrial settings.
The KPF supports copper or aluminum cables with a maximum size of #4/0 AWG. This flexibility allows engineers to standardize on a single protection device across mixed conductor types in a facility, reducing stocking requirements and simplifying installation in existing panels.
The KPF is rated for 600 V and provides a 200 kAIC interrupt rating. These ratings ensure rapid fault clearance for high-energy circuits while maintaining compatible protection within typical industrial switchgear and panel assemblies.
Yes, the KPF is RoHS compliant, aligning with environmental and regulatory standards. This helps ensure safer material usage and easier compliance in regulated facilities without sacrificing performance in high-energy applications.
Install using the center bolt end and offset bolted end configuration to match your busbar geometry. The device features a compact footprint (2.5 in depth x 2.75 in width x 1.75 in height) and a non-indicating status, which simplifies mounting in crowded enclosures and allows status monitoring to remain centralized elsewhere.
