Eaton KCZ Cable Limiter for Industrial Panels - 200 kAIC
Part Number: KCZ
Quick Summary
The Eaton KCZ cable limiter protects copper feeders by interrupting fault currents in industrial panels. Engineers often struggle to select protection that combines high fault tolerance with straightforward installation and clear performance data. This unit lists a 200 kAIC interrupt rating and RoHS compliance, though no SIL, CE, or IP certifications are specified in the data, so regulatory requirements should be confirmed with Eaton for regulated environments. By aligning with copper #3 AWG conductors and a compact footprint, it supports faster project delivery while reducing on-site complexity and lifecycle costs. The KCZ fits seamlessly into Wiring & Connectivity strategies and complements Bussmann series protections for reliable, maintainable systems.

FAQs
Yes. KCZ is designed for copper conductors sized #3 AWG, ensuring reliable contact and compatible terminations within Bussmann KCZ configurations. When wiring, verify connector type and torque specs per the Eaton installation guide and ensure the limiter aligns with upstream protection coordination for your panel layout.
The KCZ cable limiter provides a 200 kAIC interrupt rating, enabling rapid response to high-energy fault currents. This rating supports protection schemes in large feeders and motor control centers, reducing equipment damage and downtime. Ensure system short-circuit levels are coordinated with upstream devices for optimal protection.
Yes, the KCZ is RoHS compliant, supporting regulatory requirements for hazardous substances in electrical components. Note that the data does not specify SIL, CE, or IP certifications; for environments requiring those standards, confirm with Eaton or obtain appropriate third-party certifications before deployment.
The KCZ has a length/depth of 1.9 inches, a width of 1.9 inches, and a height of 8.75 inches, with a weight around 1.7 pounds. This profile supports a compact mount in panels while leaving space for wiring and connectors. Always verify mounting clearance in the enclosure prior to installation.
KCZ is non-indicating, meaning it does not provide a visual fuse status. To monitor operation, pair the limiter with external diagnostics or panel-mounted indicators and testing routines. This approach reduces component count while preserving visibility through a separate monitoring system.
