FAQs
DFJ-175 uses blade end x blade end connections designed for quick panel mounting. Plan for a standard 1 in length, ensure sufficient clearance in dense enclosures, and verify compatible Class J holders. Use proper torque on blade terminals to maintain reliable contact and minimize contact resistance, enabling consistent protection in motor drives and control circuits.
Yes. The DFJ-175 is rated for 600 Vac or less and 450 Vdc or less, with an interrupt rating of 200 kAIC at 600 Vac and 100 kAIC at 450 Vdc. This makes it suitable for mixed AC/DC protection schemes in modern automation gear, including drives and switchgear, while maintaining a compact Class J form factor.
The DFJ-175 is UL Listed, CSA Certified, and CE Marked RoHS compliant. These certifications support regulatory compliance in North America and Europe, facilitate manufacturer auditing and supplier qualification, and help ensure traceability during quality assurance and field inspections across global installations.
Common applications include protection for motor drives, power distribution panels, and control circuits in automation systems. Its high interrupt rating and Class J design suit switchgear and control panels operating in 600 Vac environments, with reliable performance in mixed AC and DC circuits typical of industrial plants.
The DFJ-175 provides rapid fault interruption, reducing arc energy and downtime, which lowers maintenance and repair costs. Its compact footprint simplifies installation in crowded panels, shortening commissioning times. Combined with global certifications, it supports predictable lifecycle costs and faster time-to-value for automation projects.
