The SEC50 fuse provides a 50 A amperage rating with a 100 kAIC interrupt capacity, delivering robust short-circuit protection for lighting feeders. This improves equipment protection and reduces downtime in high-load fluorescent systems. It’s well suited for installations where reliability and fast clearing are critical, such as commercial lighting retrofits. Rated for 480 Vac and 300 Vdc, the fuse supports both AC lighting circuits and DC control paths within same equipment, simplifying design and stocking while reducing part counts. The compact 2.25 in length with a 0.41 in width and height enables installation in cramped fixture enclosures, helping maintain clearance and minimizing modification requirements. Constructed with a glass-melamine tube and Class G construction, the fuse provides predictable performance under typical fixture conditions and remains non-indicating to simplify panel indicators. UL Listed and CSA Certified with RoHS compliance, it aligns with applicable safety and environmental standards, easing procurement and compliance workflows. Standard packaging simplifies inventory management and reorder processes, while its universal footprint facilitates compatibility with common fuse blocks and fixture assemblies. The SEC50 supports reliability, ease of maintenance, and cost control for lighting systems across offices, warehouses, and retail spaces. For ongoing reliability, verify voltage rating and current during routine maintenance and follow Eaton’s installation guidelines for compatible fixtures.

FAQs
SEC50 is sized for standard installation in typical fixture enclosures and fuse blocks, featuring a 2.25 inch length and a glass-melamine tube. With a 50 A rating and 100 kAIC interrupt capacity, it protects fluorescent lighting feeders against overcurrent while remaining easy to source and replace in ongoing maintenance programs.
The SEC50 provides a voltage rating of 480 Vac and 300 Vdc, with a 100 kAIC interrupt capacity, enabling reliable fault clearing in both AC lighting circuits and DC control paths. This ensures rapid disconnection of fault currents, reducing the risk of equipment damage and downtime in commercial lighting installations.
Yes. The SEC50 is UL Listed and CSA Certified, with RoHS compliance. These certifications support safety and regulatory acceptance, while RoHS helps meet environmental and sustainability goals in modern facilities.
Installation is straightforward in standard fixture compartments thanks to its compact form factor and standard packaging. The 50 A rating paired with a high interrupt capacity reduces nuisance trips and extends fixture life, delivering lower maintenance costs and improved uptime over the service life of the lighting system.
Reliability is supported by UL Listed, CSA Certified, and RoHS-compliant design, alongside a robust 100 kAIC interrupt rating. Spare parts availability is enhanced by standard cataloging (SEC50) and compatible glass-melamine construction, which aligns with common stocking practices in facilities maintenance inventories.
