FAQs
The DFJ-8 uses a clip-lock connection and follows a standard Class J footprint, enabling straightforward replacement in compatible Eaton Bussmann style panels. This design supports quick field installation, reduces service time, and minimizes misalignment risks during retrofits or initial builds. Engineers can source spare fuses with confidence due to the established Bussmann DFJ series ecosystem and consistent mounting geometry.
The DFJ-8 provides an 8 A amperage rating with a 600 Vac maximum and a 450 Vdc limit. Its interrupt ratings are 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc, ensuring fast fault clearance and reduced arc energy for safer machine operation. This makes it suitable for high-energy industrial applications while maintaining reliable protection in control circuits and motor drive interfaces.
Yes. The DFJ-8 is designed for motor drives, power distribution, and control panels in manufacturing. Its high interruption rating, Class J construction, and clip-lock mounting provide robust protection against overcurrent events, while remaining easy to replace in standard drive and panel architectures. The fuse’s RoHS and CE compliance also support integration into regulated industrial environments.
The DFJ-8 is UL Listed and CSA Certified, with CE marking and RoHS compliance. These certifications support regulatory compliance for safety and environmental standards, simplify approvals in many global markets, and help ensure traceability and reliability in electrical protection components used in industrial control systems.
Using the DFJ-8 can lower maintenance time through predictable nuisance-trips reduction and easy field replacement due to the clip-lock Class J design. The high interrupt ratings protect critical loads, potentially reducing downstream equipment damage and downtime. Staff can stock standard Bussmann DFJ-8 parts for consistent procurement, contributing to lower total cost of ownership in automation and control panel applications.
