Eaton KCM-B Cable Limiter - 200 kAIC, 600 V, RoHS
Part Number: KCM-B
Quick Summary
The Eaton KCM-B cable limiter protects copper 500 kcmil cables in high-energy power distribution applications. It addresses recurring nuisance trips and uncertain fault isolation by providing reliable overcurrent protection. RoHS compliant with a 200 kAIC interrupt rating and a 600 V rating helps meet code requirements across industrial facilities. In practice, this device integrates with Eaton Bussmann series protection and reduces downtime while simplifying procurement. For reliability engineers and procurement teams, KCM-B offers a straightforward, compliant solution that aligns with uptime and safety goals. Its molded rubber boot enhances field durability and protects terminations during installation and service changes. The non-indicating fuse status simplifies visual checks where indicators are not required by local codes.

FAQs
Install the KCM-B in the service entrance or feeder location approved for Bussmann-series protection. Ensure the 500 kcmil copper conductors are clean, properly cleated, and seated in the limiter’s terminations. Use the molded rubber boot for moisture protection and verify the 600 V rating is suitable for the system voltage. Follow local electrical codes and Eaton installation guidance for a secure, compliant fit.
KCM-B is rated for 600 V and provides a 200 kAIC interrupt capability, which is designed to safely interrupt fault currents in high-energy installations. Its copper construction and robust housing support reliable operation under demanding service conditions, reducing the likelihood of nuisance trips and downtime in feeders and service entrances.
Yes, the KCM-B is RoHS Compliant, meaning it meets limits on hazardous substances and supports safer, environmentally responsible manufacturing and disposal. This helps align your procurement and maintenance activities with regulations common in many regions and simplifies supplier compliance reporting for industrial projects.
The KCM-B features a molded rubber boot that enhances protection at terminations, improving resistance to moisture and dirt during field installations. While not providing a stated IP rating, this boot design supports reliable operation in challenging environments typically found in outdoor or demanding indoor applications when paired with proper enclosure and installation practices.
Choosing KCM-B delivers measurable uptime benefits through robust 200 kAIC protection for 500 kcmil copper feeders, reducing fault-related downtime. Its compact dimensions, RoHS compliance, and integration with Eaton Bussmann catalogs streamline procurement, stocking, and maintenance, lowering total cost of ownership while helping meet safety and regulatory requirements.
