Feature: High-speed interruption minimizes fault energy, protecting drives, motors, sensors, and other critical electronics in modern motor control centers. Business impact: This capability reduces unplanned downtime, minimizes arc- flash exposure, and lowers costly component replacements across conveyors, pumps, and robotics cells. Application: Ideally suited for industrial panels and power distribution in harsh environments where fast fault clearance safeguards uptime, safety, and overall equipment longevity. Feature: Clip-lock connection combined with Class J design delivers reliable mechanical seating and robust retention inside crowded enclosures. Business impact: Installation becomes faster, misalignment risk is reduced, and field servicing is simplified, driving shorter commissioning windows and lower commissioning costs. Application: Particularly beneficial for retrofit projects and new builds with limited cabinet space, where rapid replacement and secure connections are essential. Feature: Melamine tube construction with a non-indicating fuse indicator provides durability while keeping panel interiors clear and easy to inspect. Business impact: This reduces maintenance overhead, supports long service life under industrial heat and dust, and improves diagnostic clarity during audits. Application: Well-suited for control panels in manufacturing, water treatment, and material handling facilities where consistent protection is required. Feature: Compliance with CE marking, RoHS compliance, UL listing, and CSA certification verifies global safety and regulatory alignment. Business impact: Streamlines regulatory approvals, accelerates supplier qualification, and minimizes site-based compliance risk for multi-site deployments. Application: Critical for OEMs and system integrators supplying equipment to Europe and North America with strict safety and environmental standards. Feature: Compatibility with Eaton Bussmann DFJ family and clip-lock terminals enables seamless integration with existing protection schemes and downstream devices. Business impact: Supports selective coordination, reduces nuisance trips, and lowers total cost of ownership by consolidating spare parts and stock. Application: Practical for industrial machines, packaging lines, and power distribution panels where standard packaging and Class J protection meet project requirements.

FAQs
DFJ-70 offers a Clip-lock connection with Class J housing, designed for rapid, secure seating in standard control panels. The melamine tube construction provides robust protection in dusty, hot industrial environments. Its non-indicating design simplifies panel layouts, while still allowing straightforward replacement and maintenance during scheduled downtime. This combination supports dense cabinet configurations and retrofit projects without sacrificing reliability.
The DFJ-70 is rated for 70 A with an interrupt rating of 100 kAIC at 450 Vdc and 200 kAIC at 600 Vac, suitable for circuits up to 600 Vac or less and 450 Vdc or less. It uses a Class J fuse design with a Melamine tube and a non-indicating indicator. This combination ensures fast fault clearance while maintaining safe, predictable behavior in industrial power circuits.
Yes. The DFJ-70’s high-speed interruption minimizes fault energy, protecting motors and drives from dangerous short circuits. Its 70 A rating with high interrupt capability (200 kAIC at 600 Vac) is ideal for motor control centers, conveyors, and robotics within harsh industrial settings. The clip-lock, Class J configuration supports quick replacements and reliable seating in compact enclosures.
DFJ-70 carries CE marking, RoHS compliance, UL listing, and CSA certification, signaling compliance with European and North American safety and environmental standards. These certifications simplify supplier qualification, regulatory approvals, and customer audits for global deployments. They also support safe integration with other certified components in a conformity assessment process.
The non-indicating DFJ-70 reduces potential panel clutter while maintaining clear protection outcomes, lowering diagnostic complexity during maintenance. Its robust build and high interrupt rating translate to longer service intervals and reduced downtime after faults. When combined with quick-clamp clip-lock installation, field labor costs drop and spare-part stocking remains streamlined for multi-site operations.
