Eaton KDF Cable Limiter for Copper 4/0 AWG - 200 kAIC
Part Number: KDF
Quick Summary
Eaton KDF cable limiter protects power distribution lines by limiting fault current in industrial circuits. When faults occur, high-energy surges can overwhelm protection coordination, leading to unplanned downtime and costly equipment damage. The product is RoHS compliant, though the datasheet does not specify CE, SIL, or IP ratings; verify certification needs for your region before deployment. Built to support copper conductors, it accommodates #4/0 AWG wiring with a 200 kAIC interrupt rating, enabling safer and more predictable protection schemes in motor control centers and switchgear. By pairing solid electrical performance with a streamlined installation path, it helps engineering teams meet uptime targets while staying compliant with environmental and safety standards.

Eaton Specification Sheet - KDF
Feature: 200 kAIC interrupt rating enables the limiter to absorb high fault energy, reducing stress on upstream protective devices and enabling faster, more reliable fault clearance. Business impact: minimized downtime and greater protection coordination. Application: switchgear and motor control centers where large fault currents are a concern. Feature: Copper wire size compatibility (#4/0 AWG) allows direct integration with common feeder conductors, reducing the need for adapters and rewiring. Business impact: lowers installation time and material costs. Application: new builds and retrofit projects with large-diameter feeders. Feature: Tubular end x offset bolted end connection provides robust, easy-to-mount interfaces. Business impact: faster commissioning and improved mechanical reliability. Application: crowded panel interiors and retrofit scenarios where space is at a premium. Feature: RoHS compliant materials support regulatory compliance and safer waste disposal. Business impact: simplifies procurement for regulated facilities and reduces environmental risk. Application: industries with strict environmental requirements. Feature: Non-indicating fuse indicator reduces maintenance checks in high-density panels. Business impact: lowers ongoing maintenance overhead and avoids misinterpretation of status in busy environments. Application: centralised monitoring schemes and high-occupancy switchgear environments. Insight: Integrates with Eaton Bussmann series catalogs anddatasheets to streamline design validation and reduce engineering risk.

FAQs
To install the KDF, follow the tubular end to offset bolted end configuration, ensuring clean mechanical interfaces with copper conductors sized #4/0 AWG. Use appropriate hardware per Eaton's installation guidelines, secure mounting to a rigid chassis, and verify conductor torque specs from the latest datasheet. The non-indicating fuse indicator means status must be verified via external protection panels, not via the limiter itself. Proper mounting reduces vibration and wear on connectors, improving long-term reliability and safety in switchgear and control centers.
The KDF cable limiter features a 200 kAIC interrupt rating, designed for high-energy fault conditions. It supports copper wire sizes up to #4/0 AWG, allowing direct connection to common industrial feeders without additional adapters. This combination provides robust fault energy handling, enhances protection coordination with upstream devices, and supports compliant operation in large motor feeders and distribution panels in industrial facilities.
Yes, the KDF is well suited for switchgear and motor control centers where large fault currents can occur. Its 200 kAIC rating and copper #4/0 AWG compatibility align with typical MCC feeder requirements, delivering reliable protection for critical equipment like motors and drives. The tubular end x offset bolted end configuration simplifies integration in crowded enclosures and supports scalable protection strategies in heavy-industry environments.
The data specifies RoHS compliance for the KDF, which means restricted hazardous substances are managed per directive requirements. The dataset does not list CE, SIL, or IP certifications, so confirm regional or project-specific certifications before procurement. RoHS compliance supports environmentally responsible procurement, while you should verify any additional regulatory needs for your end-use environment to avoid compliance gaps.
Using the KDF can reduce downtime by stabilizing fault currents and protecting downstream equipment, which lowers unplanned outages and maintenance cycles. Its large conductor compatibility minimizes wiring changes, while the robust 200 kAIC rating supports long-term reliability in high-energy networks. Lifecycle cost benefits include reduced spare parts, faster retrofit cycles, and simpler panel maintenance in busy industrial facilities.
