The 25 A amperage rating paired with a 600 Vac/600 Vdc rating enables precise matching to motor starters and control circuits, reducing nuisance trips and protecting valuable equipment. This precision supports uptime in manufacturing lines by preventing unnecessary outages and shortening repair cycles. The fuse offers high interrupt ratings of 50 kAIC at 600 Vdc and 300 kAIC at 600 Vac, enabling safe interruption of heavy fault currents and protecting feeders and switchgear from damage. Its non-indicating design with blade-end connection simplifies field service and enables quick replacement in standard CF fuse holders, reducing downtime during maintenance. The robust construction uses glass-filled PES material and tin-plated copper alloy terminals, allowing reliable operation across harsh environments from -40°C to 80°C and resisting wear from frequent cycling. Compliance and certifications—CE, RoHS, UL Listed, CSA Certified—support traceability and regulatory adherence across global projects. Compatibility with common Bussmann CF accessories and assemblies such as TCFH30N and CCP2-3-30CF streamlines procurement and inventory management for engineering teams.

FAQs
The FCF25RN uses a blade-end connection designed for Bussmann CF fuse holders. To install, align the blade terminals with the holder contacts, press until seated, and ensure the panel or enclosure supports 1 element per cube fuse. This design supports quick field replacement and reduces service time during maintenance.
The fuse is rated for 25 A with 600 Vac and 600 Vdc operation. It provides 50 kAIC interrupt rating at 600 Vdc and 300 kAIC at 600 Vac. The device is UL Listed and CSA Certified and RoHS/CE compliant, with a non-indicating indicator and a blade-end connection for straightforward integration.
Yes. The FCF25RN is CE Marked and RoHS Compliant, in addition to UL Listed and CSA Certified, meeting widely adopted international safety and environmental requirements and simplifying regulatory reporting for multinational projects.
Dimensions are 1.88 in (length) × 1.75 in (height) × 0.75 in (width). The operating temperature range is -40°C to 80°C, and the fuse body is glass-filled PES with tin-plated copper alloy terminals for durable field performance.
Ideal for low-voltage branch circuits in electrical protection and circuit control across panels and machines, the FCF25RN delivers reliable overcurrent protection with fast response, high fault-current interrupt capability, and easy replacement. This translates to reduced downtime, lower maintenance costs, and improved regulatory compliance, contributing to a favorable total cost of ownership in industrial environments.
