FAQs
FCF1RN uses a blade-end connection and is designed to fit standard Eaton Bussmann Class CF holders and assemblies. It is compatible with TCFH30N and CCP2-3-30CF configurations, ensuring a reliable mechanical and electrical fit in control panels. This compatibility reduces installation time and minimizes the risk of improper fuse seating during replacement.
The FCF1RN is rated 1 A with a voltage rating of 600 Vac and 600 Vdc. It provides an interrupt rating of 300 kAIC at 600 Vac and 50 kAIC at 600 Vdc, and a typical response time of 4 minutes at 200% delay. These specs support fast, selective protection for low-current circuits while tolerating short overload events.
This fuse is well suited for industrial control panels, motor circuits, and DC distribution networks at 600 V class systems. Its compact size and blade-end design enable easy integration into crowded enclosures, while its ratings support both AC and DC applications typical of industrial automation, process control, and electrical protection schemes.
FCF1RN carries UL Listed and CSA Certified marks, along with CE RoHS compliance. These certifications support global regulatory requirements and supplier qualifications, helping to streamline procurement, audits, and cross-border deployments in manufacturing, automotive, and energy sectors.
Consider the blade-end connection and the enclosure space when planning replacements. The device measures 1.88 in L × 1.75 in H × 0.75 in W, with a -40°C to 80°C operating range and glass-filled PES material with tin-plated copper terminals. Use in compatible fuse holders like TCFH30N or CCP2-3-30CF assemblies to ensure reliable contact and ease of maintenance.
