Feature → Business Impact → Application: The NON fuse is a 25 A, non-current-limiting device, which means it provides dependable fault protection without impeding normal startup in motors and drives, reducing nuisance trips and downtime in manufacturing lines. This translates to lower maintenance costs and more predictable production schedules in control panels and machine enclosures. Feature → Business Impact → Application: A 50 kA interrupt rating at both 250 VAC and 125 VDC delivers high fault-clearing capability, protecting downstream components and wiring from arc flash events while supporting safe shutdown procedures in switching gear and power distribution. Feature → Business Impact → Application: Ferrule-end connections with a 2 in length and compact 0.56 in dimensions simplify retrofits and new installations, enabling quick, secure wiring in standardized panels and compact electrical housings. Feature → Business Impact → Application: The Class H designation and standard packaging (10 per pack) streamline stocking, refurbishment, and replacement planning in maintenance inventories for industrial plants. Feature → Business Impact → Application: Being CE marked provides regulatory confidence for European projects, complementing other compliance programs and reducing sourcing risk when sourcing general protection fuses for MCCs and control cabinets.

FAQs
The NON-25 is a general-purpose, non-current-limiting Class H fuse rated at 25 A with a 50 kA interrupt rating, intended for protection of electrical circuits in control panels and machinery. Its ferrule-end connections and compact form simplify installation in crowded enclosures while delivering reliable fault protection for upstream devices and wiring.
As a non-current-limiting fuse, the NON-25 does not suppress inrush or startup surges. This makes it suitable for circuits where controlled current limiting is not required, reducing nuisance trips during motor startups. Pairing it with appropriate soft-start strategies or drive configurations helps maintain protection without impacting performance.
The NON-25 uses ferrule-end connections and measures 2 in in length with 0.56 in width and height. It is packaged as a standard fuse and is available in quantities of 10 per pack, making it easy to stock and replace in common control panels and machine enclosures with Ferrule wiring.
The NON-25 is CE marked, aligning with European safety and regulatory expectations. This certification supports compliance in European installations and tender documentation, easing acceptance in projects governed by EU standards while providing a clear indication of conformance to essential safety requirements.
Designed as a reliable, non-current-limiting fuse with a robust 50 kAIC interrupt rating, the NON-25 reduces unexpected outages and simplifies replacement in routine maintenance. Its 25 A rating, standard ferrule connections, and packaging in convenient quantities help owners manage spare parts costs and minimize downtime during fuse replacements.
