FAQs
The DFJ-6 is a bolt-on, Class J high-speed fuse designed to fit standard Bussmann DFJ assemblies and compatible holders in electrical protection panels. It mounts in a compact 0.74 in width space and uses a melamine tube for robust performance. It pairs with other DFJ family devices for consistent protection across panels and drive systems.
The DFJ-6 is rated at 6 A and supports voltages up to 600 Vac or less and 450 Vdc or less. Its interrupt ratings are 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc, enabling fast fault interruption to protect motor drives, transformers, and automation circuits from damaging surges.
DFJ-6 carries CE Marking and RoHS compliance, plus CSA Certified and UL Listed certifications. These approvals support global deployment, regulatory compliance in diverse regions, and safer installations in industrial environments.
The DFJ-6 is ideal for motor drives, control panels, and electrical protection schemes in industrial automation. Its Class J, bolt-on design and high interrupt capability make it well-suited for both new builds and retrofits where fast protection and reliable performance are priorities.
Installation is straightforward with a bolt-on connection and a non-indicating indicator. Use standard Bussmann DFJ mounting hardware and ensure the amperage and voltage ratings match the protected circuit. Because it’s part of the DFJ family, replacement and stocking are simplified, and certifications support ongoing regulatory compliance.
