JJN-100~TRON FAST ACTING FUSE CLASS T
Current-limiting operation with a 10 A rating and 300 V class protects downstream drives by clamping fault energy to safe levels, reducing insulation stress and collateral damage. This translates to fewer nuisance trips, lower maintenance costs, and improved uptime across critical lines. It is well suited for VFD line protection on motor drives, conveyors, pumps, and machine tools in harsh environments. Class T fast-acting protection delivers selective response that minimizes disruption to healthy circuits while preserving overall system integrity. This reduces the likelihood of cascading faults in panels and power rails, enabling smoother commissioning and less rework. Ferrule-end terminations simplify field wiring and ensure reliable connections in compact control cabinets and equipment racks. With a 200 kAIC interrupt rating at 300 V, the fuse safely interrupts high fault currents, protecting equipment and supporting safe shutdown sequences. This capability is valuable for heavy machinery, large motors, and process lines where fault energy can be extreme. The JJN-10 remains compatible with standard Bussmann fuse bases and common 300 V control circuits. Ferrule-end connections offer robust, vibration-resistant terminations that accelerate panel assembly and reduce field rework. The small footprint—0.88 in length, 0.41 in width, 0.41 in height—lets designers pack protection into crowded panels without compromising access for testing or replacement. The non-indicating design minimizes visual clutter in control cabinets while delivering proven reliability. CE marking and RoHS compliance address regulatory and sustainability goals for global OEMs. The standard packaging accommodates bulk stocking and predictable lead times, supporting streamlined procurement and maintenance planning. In addition, the 10-count quantity aligns with common spare-fuse strategies, helping service teams minimize downtime by ensuring ready replacements are on hand when protection devices reach end of life.

FAQs
The JJN-10 uses ferrule-end terminations and is designed for standard Bussmann fuse bases and compatible low-voltage fuse holders. Ensure the holder supports ferrule-end contacts and is rated for 300 V. For best results, pair with Eaton Bussmann series holders specified for Class T ferrule-end fuses to ensure secure crimp connections and compliant insulation.
The 200 kAIC interrupt rating indicates the fuse can safely interrupt very high fault currents without side effects such as arcing or excessive fault energy. This reduces the risk of collateral damage to upstream components, enables safer shutdown sequences, and improves reliability when protecting motor drives and power rails in high-inrush applications.
Yes, the JJN-10 is suitable for VFD line protection in 300 V circuits and can be used as one leg of a 3-phase protection scheme. In three-phase applications, use multiple JJN-10 fuses in appropriate configurations per your drive and panel design to ensure balanced protection and coordinated fault clearing.
The JJN-10 carries CE marking and RoHS compliance, ensuring conformity with European safety, health, and environmental requirements. These certifications help manufacturers meet regulatory demands, facilitate cross-border sales, and support sustainable product lifecycles in global automation projects.
With a non-indicating indicator, JJN-10 fuses are simple to visually inspect during routine checks. Stocking a 10-count quantity aligns with common panel protection needs, reducing downtime when replacements are required. The fuse’s compact size and standard packaging improve inventory efficiency and ease the replacement process during scheduled maintenance.
