Eaton LCU3500 LCU fuse - CSA Certified UL Listed

The LCU3500 delivers a 3500 A amperage rating coupled with a 200 kAIC interrupt rating, enabling robust protection for main feeders. This high interruption capacity minimizes fault energy, reducing the risk of extensive equipment damage during a short circuit and shortening outage durations. It is well-suited for heavy industrial power distribution in manufacturing plants, processing facilities, and large data centers where uptime is mission-critical. Class L construction paired with a non-indicating fuse design streamlines panel layouts and lowers replacement costs. The absence of an integrated indicator can be offset by standard plant monitoring practices and spare-part planning, making it an attractive choice for large switchgear banks where visibility is managed elsewhere. Glass melamine tubes with silver-plated end bells provide strong dielectric strength and mechanical resilience under vibration and temperature cycling. This trusted construction supports long service life in factory floors, outdoor enclosures, and other challenging environments, reducing unscheduled maintenance and parts stocking. Bolt mounting offers a secure, field-friendly installation method that simplifies replacement during scheduled maintenance or after fault events. Standardizing on bolt-mount fuses also accelerates stocking and interchangeability with other Edison fuse families, improving spare-part optimization. RoHS compliance with CSA certification and UL listing fulfills rigorous regulatory requirements for North American and global projects. This combination lowers procurement risk, streamlines approvals, and supports warranty and quality programs in industrial automation settings.
