FAQs
The DFJ-70-W uses a clip-lock connection that snaps securely into standard fuse holders designed for Class J devices. With a length of 4.83 in, width of 1.18 in, and height of 1.19 in, it fits compact panels and MCCs. Ensure proper clearance and align the clip-lock terminals with matching conductors or bus bars for a clean, vibration-resistant connection. This minimizes rework during panel assembly and improves reliability in automated environments.
The DFJ-70-W is a 70 A high-speed fuse rated for up to 600 Vac or 450 Vdc. Its interrupt ratings are 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc, supporting fast fault interruption and robust short-circuit withstand. This combination protectors downstream equipment like motors and drives while meeting demanding industrial safety and reliability requirements.
This fuse is well-suited for industrial automation, motor drives, CNC machinery, conveyors, and power distribution panels. Its Class J design, clip-lock connection, and high interrupt ratings make it a dependable choice for applications requiring fast protection with high current capacity, such as packaging lines, material handling systems, and machine tool controls.
The DFJ-70-W carries UL Listed and CSA Certified certifications and CE Mark RoHS compliance. These approvals support regulatory compliance in North America and Europe, simplify supplier qualifications, and reduce risk during audits and cross-border deployments in global facilities.
As a non-indicating fuse, the DFJ-70-W relies on protective coordination and system diagnostics to signal failure. Plan for periodic panel checks and spare inventory to minimize downtime. Its compact size and standard packaging simplify stocking, while reliable protection reduces component damage and maintenance cycles, delivering lower total cost of ownership over the equipment’s lifecycle.
