Eaton Bussmann CLS fuse 8CLS-3R - 50 kAIC, 100A

Single-barrel design with a 3R designation keeps the 8CLS-3R compact while delivering reliable protection. This layout reduces panel footprint and simplifies wiring, lowering installation time, panel costs, and cooling loads in dense electrical cabinets. It supports quick retrofits and straightforward field swapping, making it a practical choice for motor control centers (MCCs) and control panels in automated manufacturing lines where space is at a premium and uptime is critical. The catalog number integration also helps maintenance teams quickly verify part compatibility during audits. With a 50 kAIC interrupt rating at 7.2 kV, the fuse clears faults quickly and supports selective coordination across feeders, reducing arc flash exposure and minimizing damage to upstream equipment. This performance translates into safer operations and shorter repair windows, especially in high-current motor circuits and heavy loads common in packaging, metals, and process industries. The 100 A operating rating aligns with common MCC feeder protection needs, avoiding overdesign while maintaining coverage for typical loads, helping optimize spare-part inventories and lifecycle costs. The 8CLS-3R’s Class R designation provides well-understood coordination with other Bussmann protection devices. Physical dimensions—15.9 in depth with a 3 by 3 in footprint and a 9 lb weight—facilitate straightforward installation in standard switchgear and control cabinets, while a compact form factor reduces thermal load and simplifies heat management in dense panels. Cataloging and procurement are simplified by the exact catalog number and UPC, reducing mis-picks and expediting stocking in maintenance warehouses. In industrial automation contexts, the Eaton Bussmann CLS fuse is a trusted choice for motor-start protection and general electrical protection, offering rugged construction and reliable specifications to help engineers meet uptime targets without compromising budget or design constraints.
