Eaton KEW Cable Limiter - 200 kAIC at 600 Vac RoHS

High-current protection is the core capability of KEW, delivering 200 kAIC interrupt rating at 600 Vac. This performance ensures fast fault clearance, minimizing arc energy and downstream damage to feeders, switchgear, and motors. In practical installations, it enables reliable operation in large-scale facilities such as manufacturing lines and data centers where uptime is critical. Conductor compatibility is a defining feature: KEW accepts 350 kcmil copper or aluminum conductors. This sizing supports heavy feeder runs without multiple devices in series, reducing inventory complexity and simplifying engineering calculations for ampacity and fault current, which translates to shorter design cycles. Mechanical flexibility simplifies field installation: the KEW design uses a center bolt end to offset bolted end configuration, enabling straightforward mounting in existing bus configurations. The compact footprint (2.5 in length, 2.75 in width, 1.75 in height) fits tight enclosures while preserving clearance for cables. Non-indicating operation reduces on-site monitoring burdens; there is no external fuse status indicator, which lowers potential maintenance points in dense control rooms. Combined with Eaton datasheets and catalogs, procurement and engineering validation are faster, with clear compatibility data for 350 kcmil Cu/Al runs. RoHS compliant design supports environmental compliance and regulatory alignment across many regions, easing purchasing approvals and reducing risk in modern industrial facilities. This device leverages Bussmann series heritage, offering proven performance in power protection applications. Physical footprint and weight contribute to installation efficiency: 4.25 lb weight and the listed dimensions enable easy handling, rail or panel mounting, and less support structure. This translates to lower labor costs during commissioning and service as part of a well-documented Eaton protection strategy.
