Eaton KDR-E Cable Limiter - 200 kAIC Fault Protection
Part Number: KDR-E
Quick Summary
KDR-E cable limiter from Eaton protects large-diameter feeder circuits by interrupting faults quickly. In practice, fault energy and protection gaps can drive costly downtime and equipment damage, so a robust limiter is essential. The data shows a 200 kAIC interrupt rating at 600 V and 750 kcmil copper conductors with tubular end x offset bolted ends, without indicating warranty or compliance; note these are not listed as certified in this dataset. This combination supports safer, more reliable protection within standard industrial wiring practices, and aligns with Eaton Bussmann series for streamlined procurement and maintenance planning, delivering tangible business value through faster repair cycles and clearer protection coordination.

Eaton Specification Sheet - KDR-E
The KDR-E delivers a 200 kAIC interrupt rating at 600 V, enabling rapid fault interruption in high-energy feeders and protecting downstream equipment from damaging arcing. This capability translates into shorter outage windows and improved safety for critical lines in manufacturing, data centers, and process facilities. Designed for 750 kcmil copper conductors, it supports heavy-duty feeder configurations with low resistance and stable voltage drop under load, maximizing current capacity and protecting cables during faults. The tubular end x offset bolted end connection simplifies mounting and integration with existing Eaton Bussmann protection schemes, reducing field labor and risk of mis-assembly. Non-indicating status reduces device footprint and ruggedness in harsh environments, while practitioners can pair this limiter with external indicators or monitoring strategies to maintain visibility during inspections. Its compact footprint—2.5 in long, 1.75 in high, 2.75 in wide—and light 0.1 lb weight enable installation in crowded panels and tight enclosures, facilitating retrofit projects and faster swaps. Compatibility with Eaton Bussmann catalogs and the KDR-E datasheet ensures consistent sourcing, accurate BOMs, and streamlined procurement workflows for engineers and buyers.

FAQs
KDR-E uses a tubular end x offset bolted end configuration designed to match common Eaton Bussmann wiring practices. When planning installation, verify bore alignment, bolt torque, and mating hardware in the switchgear or panel where the limiter will be mounted. The 2.5 in length, 1.75 in height, and 2.75 in width should be checked against available space to avoid clearance issues and to ensure a secure, code-compliant fit.
Key specifications include an interrupt rating of 200 kAIC and a voltage rating of 600 V, along with a copper conductor size of 750 kcmil. These figures indicate strong fault-current handling, suitable endurance for heavy feeder applications, and compatibility with large-diameter copper conductors. Confirm these values align with your system fault current, bus rating, and protection coordination study.
Yes. The 200 kAIC interrupt rating at 600 V and the 750 kcmil copper conductor sizing make KDR-E appropriate for motor feeders and industrial distribution panels where high fault currents may occur. Ensure your protection coordination study accounts for the device’s non-indicating status and verify compatibility with your existing protective relays and indicators to maintain visibility during operation.
The provided data indicate warranty and compliance fields as Not Applicable, and no CE, SIL, IP, or other certifications are listed. For formal approvals, consult Eaton’s official datasheet and catalogs (KDR-E specification sheet) or contact Eaton directly to confirm current certifications and site-specific compliance requirements before installation.
Deploying KDR-E can reduce downtime and equipment damage by enabling rapid fault energy limitation, which translates to shorter outage durations and lower repair costs in high-energy feeder environments. While exact ROI depends on system fault rates and maintenance practices, the 200 kAIC rating and rugged copper construction support long service life and fewer field interventions, contributing to lower total cost of ownership over time.
