Eaton Specification Sheet - KCY
200 kAIC interrupt rating provides robust short-circuit protection to minimize downstream damage and downtime, improving system reliability in medium to large electrical distributions. This translates to tangible business value by reducing maintenance events and speeding up commissioning in switchgear and MCC applications, while supporting long-term compliance with industrial safety standards. Copper wire size #4 AWG compatibility ensures a straightforward retrofit or new-build installation with common feeder configurations, enabling predictable electrical performance and simplifying procurement for panel shops and contractors. The non-indicating fuse indicator reduces panel clutter and simplifies enclosure layouts, helping technicians focus on critical diagnostics and external monitoring, which reduces installation time and potential misreads during maintenance. RoHS compliance confirms adherence to hazardous substance restrictions across regional supply chains, supporting global manufacturing and customer requirements without additional processing steps. The KCY’s footprint—1.9 in by 1.9 in base and 8.75 in height—along with a 1.7 lb weight, delivers a compact, rugged solution suitable for tight enclosures and dense layouts common in modern data centers, manufacturing floors, and energy plants. Documentation and catalog resources from Eaton further ease design validation and compraization through the Bussmann KCY family and spec sheets.

FAQs
The KCY cable limiter is designed specifically for copper #4 AWG conductors, aligning with common feeder configurations in switchgear, panels, and MCCs. Its dimensions and weight support straightforward mounting in typical enclosures, while the non-indicating design simplifies panel layouts. For installation, reference the Eaton KCY specification sheet to confirm clearances and termination practices.
Eaton KCY offers a 200 kAIC interrupt rating, making it suitable for high-current protection in medium- to large-capacity switchgear, motor control centers, and distribution panels. This rating enables rapid fault isolation and reduces collateral damage during faults, supporting uptime in critical process and manufacturing environments.
Yes, KCY is RoHS compliant, which helps align with restricted-substance regulations across many regions. This simplifies supplier qualification, reduces compliance risk, and supports global manufacturing requirements for OEMs and integrators building panels for sectors with strict environmental standards.
Plan for the KCY’s compact footprint (1.9 in L, 1.9 in W, 8.75 in H) and ensure adequate clearance for copper conductors #4 AWG. Use the Eaton KCY datasheet for mounting guidelines, clearance, and termination recommendations. The non-indicating design means you’ll rely on external monitoring or remote indicators for status feedback.
