Eaton Specification Sheet - BP/NON-50
Feature: Non-current-limiting design keeps nuisance trips in check while protecting wiring insulation. Business Impact: Lowered downtime and longer component life in control panels. Application: Light-duty automation circuits where short inrush is possible but precise overcurrent protection is required. The result is improved productivity and minimized unplanned outages. Feature: 50 A amperage rating with a 50 kAIC interrupt rating at 125 Vdc and 250 Vac. Business Impact: Robust short-circuit protection that complies with typical electrical distribution requirements, reducing risk of equipment damage. Application: PLC cabinets and small motor control centers needing reliable clearance during fault events. This supports safer, code-compliant installations and cost-effective protection strategies. Feature: 250 Vac / 125 Vdc voltage ratings. Business Impact: Flexible NA/AC/DC protection within the same device reduces part counts and simplifies spares inventory. Application: Mixed-voltage control panels and instrumentation bays common in machine automation. Feature: Ferrule end x ferrule end connection and nickel-plated caps. Business Impact: Quick, secure wiring with durable contacts, enabling faster assembly and longer service life. Application: Field replacements and panel upgrades where crimped ferrules are preferred for reliability and repeatability. Feature: Class K5 construction and blister packaging. Business Impact: Predictable break characteristics and easy handling during procurement and stocking. Application: OEM and service kits where standardization and clear documentation matter for maintainability and compliance. Feature: Compact 3 in × 0.81 in × 0.81 in footprint and 0.236 lb weight. Business Impact: Minimal space impact in crowded panels, enabling denser layouts and easier retrofits. Application: Enclosed control panels and compact switchgear where space is at a premium.

FAQs
Yes. BP/NON-50 uses ferrule end x ferrule end terminals, which simplifies crimping and ensures a secure connection in control panels. For best results, crimp ferrules to manufacturer specifications and terminate onto standard bus bars or terminal blocks used in light-duty circuits.
BP/NON-50 is a 50 A fuse with a 50 kAIC interrupt rating at both 125 Vdc and 250 Vac. It is rated for 250 Vac and 125 Vdc, with non-current-limiting behavior suitable for applications where inrush is managed and predictable fuse clearing is required.
Yes. The device supports 250 Vac mains and 125 Vdc control circuits, providing a single protection device for mixed-voltage panels while maintaining safe clearance and consistent operating characteristics.
BP/NON-50 is CE Marked, indicating conformity with European safety requirements for electrical equipment. Always verify regional certifications relevant to your installation if you operate outside CE regions.
As a non-current-limiting, non-indicating fuse, BP/NON-50 requires periodic inspection of fuse status and panel electrical integrity. Its compact form and nickel-plated caps support durable operation, but standard spares stocking and scheduled panel audits are recommended to minimize downtime during replacement.
