Eaton DFJ-150 High Speed Fuse - 600 Vac Class J
Part Number: DFJ-150
Quick Summary
The Eaton DFJ-150 high speed fuse protects electrical circuits in industrial panels and drive systems. Engineers often face nuisance trips and uptime risk when protection is too slow or mis-specified for fast transient events. This device carries CSA Certified, UL Listed, and CE RoHS compliance, underscoring robust regulatory alignment for global deployments. With a 150 A rating and compatibility for 600 Vac / 450 Vdc, it provides precise fast-acting protection for motors, inverters, and control circuits. The Class J, non-indicating design and melamine tube support compact panel layouts, easier maintenance, and improved heat management. For OEMs and integrators, the DFJ-150 translates to higher uptime, lower replacement-cost exposure, and consistent safety margins across critical automation assets.

Datasheet - FNQ-30
The DFJ-150 delivers 150 A protective capability, which directly reduces the risk of damage from short-circuit events and minimizes downtime in industrial drives and machine controls. This translates to measurable improvements in equipment availability and lower replacement costs in high-demand automation lines. The device is rated for 600 Vac and 450 Vdc, enabling safe integration into mixed-voltage control cabinets and motor drive circuits without compromising protection performance or panel density. Its 200 kAIC interrupt rating at 600 Vac and 100 kAIC at 450 Vdc ensures rapid fault clearance even in high-current faults, safeguarding upstream power supplies and wiring. The melamine tube construction and Class J form factor deliver robust arc-quenching capability in harsh industrial environments, while the non-indicating design keeps panel openings minimal for easier servicing. Compliance with CE, RoHS, CSA, and UL standards provides confidence in global installations and supplier audits. This fuse is compatible with standard Bussmann DFJ mounting schemes, supporting straightforward retrofits and spare-part stocking. Overall, the DFJ-150 improves protection accuracy, simplifies inventory management, and supports safer, more reliable automation ecosystems.

FAQs
The DFJ-150 is optimized for industrial protection in panels and motor-drive systems. It supports 150 A loads with fast clearing at up to 600 Vac or 450 Vdc, making it ideal for motors, drives, and control circuits in manufacturing environments. Its Class J, non-indicating design keeps assemblies compact while delivering reliable short-circuit protection.
Key ratings include 150 A amperage, 600 Vac / 450 Vdc voltage, and 200 kAIC at 600 Vac plus 100 kAIC at 450 Vdc. For 3-phase drives, these ratings ensure rapid interruption of fault currents without nuisance tripping, protecting transformers, busbars, and power electronics while maintaining system availability.
Yes. The DFJ-150 carries CE Marking and RoHS compliance, and it is CSA Certified and UL Listed, meeting international safety and environmental standards. This simplifies regulatory clearance for global deployments and audits across automotive, process, and general manufacturing sectors.
Non-indicating fuses do not require visual fault indication, reducing panel openings and simplifying replacement routines. This is advantageous in tight or high-density control panels, enabling quicker swaps, less dust ingress, and shorter maintenance windows without compromising protection performance.
Plan for standard Bussmann DFJ mounting compatibility and replace after fault events or during preventive maintenance. With a 6 in length and standard package, stock spares align with typical panel-fuse inventories. Consider keeping replacements in the same class and rating to maintain consistent protection margins across drives and control circuits.
