Eaton BP/NON-40 Fuse - Class K5, 50 kAIC @ 125/250V
Part Number: BP/NON-40
Quick Summary
BP/NON-40 fuse from Eaton is a non-current-limiting device designed for light-duty circuit protection in industrial panels. Engineers often struggle to balance compact panel layouts with reliable fault protection, and choosing the wrong fuse can lead to nuisance trips or wasted space. CE Marked compliance supports regulatory readiness, while the Class K5 designation and ferrule-end connections ensure compatibility with standard control-panel hardware. This solution also reduces inventory complexity by using a common Bussmann-series form factor in blister-pack packaging, helping procurement teams streamline sourcing. For serviceability and long-term reliability, the BP/NON-40 aligns with modern automation environments where ease of installation and predictable performance matter most.

Eaton Specification Sheet - BP/NON-40
The BP/NON-40 delivers value through a clear Feature → Business Impact → Application pattern. Feature: Non-current-limiting protection with a 40 A rating. Impact: Minimizes arc energy and maintains system availability in light-duty circuits, reducing downtime. Application: Control panels and small automation circuits where fault current is known to be moderate and fast clearing is not required. Feature: 50 kAIC interrupt capability at 125 Vdc and 250 Vac. Impact: Provides robust protection against high fault currents in commercial/industrial environments, improving safety margins and equipment life. Application: Power feeds to motor starters and control circuitry in machine coolers or packaging lines. Feature: Ferrule end x ferrule end connections. Impact: Fast, reliable installation with compatible terminations in standard panel boards. Application: Replacements or upgrades in legacy panels without reterminating conductors. Feature: Nickel-plated caps and blister-pack packaging. Impact: Corrosion resistance and easier handling during stocking and installation. Application: Field service and OEM builds where durability and packaging are valued. Feature: Class K5 rating and CE Marked compliance. Impact: Ensures industry-standard protection class and regulatory alignment for European and multinational deployments. Application: Industrial control gear requiring certified components with predictable performance. Feature: 3 in length and compact 0.81 in square profile. Impact: Deep but narrow footprint that preserves panel space. Application: Tight enclosures in control cabinets and distributed automation nodes. Feature: 40 A with 50 kAIC interrupt rating. Impact: Safe, reliable protection for light-duty circuits while meeting common fault-current specs. Application: Small control circuits in packaging machines, conveyors, and process sensors.
