FAQs
The FWH-700A uses blade end x blade end connections and is designed for stud mounting as well. For panel installs, align the blade terminals with the bus bars, tighten lugs to manufacturer torque specs, and ensure proper clearance for heat. Always follow the Eaton datasheet and your panel’s engineering instructions to maintain safe, reliable operation.
The device is rated for 700 A RMS with an interrupt rating of 200 kAIC at 1000 Vac and 50 kAIC at 500 Vdc. These ratings support quick fault interruption in high-current systems, reducing arc fault exposure and improving protection coordination in power distribution and motor-drive applications.
Yes. The FWH-700A is CSA Certified and UL Recognized, CE Marked, and RoHS compliant, which helps streamline regulatory approvals for global deployments. This makes it suitable for industrial panels, OEM assemblies, and field retrofits where strict safety and environmental requirements apply.
This fuse supports blade end x blade end connections and stud mounting, offering installation flexibility. When retrofitting, verify spare spacing, bus-bar compatibility, and mounting clearance. Use the standard packaging and follow the datasheet for torque and lead management to ensure reliable electrical and mechanical performance.
The FWH-700A provides fast fault clearance, reducing downtime and maintenance costs. Its regulatory compliance and robust interrupt capabilities improve protection coordination, lowering the risk of cascading trips. Although a higher upfront cost may be noted, the total cost of ownership decreases through fewer outages, simpler stocking, and longer equipment life.
