FAQs
The LCU2000 fuse uses bolt mounting, a common method that enables secure, vibration-resistant installation in standard fuse blocks and switchgear. This compatibility simplifies field replacement and minimizes downtime during maintenance. When upgrading existing assemblies, verify flange spacing and fastener torque per Eaton specifications to ensure a safe, code-compliant integration.
Key ratings include a 2000 A amperage rating, 200 kAIC interrupt rating, and a 600 V voltage rating. This makes the LCU2000 suitable for high-current main feeders, service entrances, and heavy equipment protection in industrial plants, manufacturing lines, and data centers where reliable fault clearing is essential.
Yes, the LCU2000 is RoHS compliant. It carries UL Listed and CSA Certified marks, providing recognized safety and compliance for North American installations. This combination supports regulatory adherence and supplier validation in regulated environments, reducing procurement risk and streamlining vendor qualification.
Class L fuses are designed to withstand and interrupt high-current fault conditions with dependable performance, balancing protection and coordination in large circuits. For the LCU2000, this means reliable fault interruption at 2000 A while maintaining system selectivity and minimizing nuisance outages, particularly in main feeders and high-demand industrial applications.
Upgrading to the LCU2000 can reduce downtime from unplanned fuse failures thanks to its high interrupt rating and robust construction. The UL Listed, CSA Certified, and RoHS-compliant design also lowers regulatory risk and potential rework. In practice, you’ll benefit from longer service intervals, faster replacements, and improved overall equipment availability.
