Eaton Specification Sheet - SP/FRS-R-40
This 40 A device uses a dual-element cartridge fuse design to provide robust protection against overcurrents while enabling selective coordination in power circuits. The business impact is reduced downtime, minimized collateral damage, and easier maintenance planning in high-demand panels. In practical terms, it fits standard Bussmann-series layouts, supports straightforward replacement, and integrates with Eaton catalogs and datasheets to streamline procurement and redesigns for expanding machinery. Its compact 5.5 in length with a 1.06 in footprint helps save enclosure space in dense panels, improving overall cabinet density and reducing installation time. The dual-element arrangement adds reliability during surge events, lowering the risk of unexpected outages in critical equipment. By aligning with Bussmann-series ecosystems, technicians benefit from consistent part availability and simplified spare-part inventories. Industry context confirms that standardization across a common fuse family can drive lower total cost of ownership and faster MTTR in manufacturing lines.

FAQs
SP/FRS-R-40 is a cartridge fuse from Eaton’s Bussmann series designed for standard Bussmann-based assemblies. It uses a conventional cartridge form factor and dimensions listed in the product data (5.5 in length, 1.06 in width, 1.06 in height) to fit typical panel spaces and fuse holders used in industrial protection applications.
As a 40 A dual-element cartridge fuse, it provides overcurrent interruption for circuits up to 40 A, with dual elements contributing to reliable operation during transient events. It is suitable for protecting industrial control circuits and power feeders in panels and machines, aligning with Bussmann-series protection standards.
Yes, for general electrical protection in control panels and industrial machinery. However, verify regional approvals (for example CE or UL/CSA) via Eaton's specification sheets, since the provided data marks compliances as Not Applicable. Matching the exact environment and enclosure requirements is essential for compliant deployment.
Regulatory needs vary by region and application. Common considerations include CE, UL/CSA markings, and IP ratings for enclosure protection. The product data indicates Not Applicable for compliances, so consult the Eaton specification sheet or contact Eaton for the precise approvals applicable to your installation site and industry.
The fuse’s 5.5 in length and compact footprint, combined with the Bussmann-series ecosystem, supports straightforward replacement and standardized spares. This can reduce MTTR, simplify procurement with a familiar catalog, and lower total cost of ownership through consistent part availability and predictable maintenance cycles.
