Feature → Business Impact → Application: The MDL3800FW01 frame-only design enables seamless integration into existing Series C protected environs, reducing installation time and minimizing panel rework, which translates to lower project labor costs on new builds and retrofit projects. This contributes to faster commissioning and improved uptime in motor control centers where space is at a premium. Feature → Business Impact → Application: Fixed thermal and fixed magnetic trip type (T186) delivers reliable overcurrent protection with instantaneous response during short-circuits, mitigating equipment damage and safeguarding critical drives and feeders in manufacturing lines. This is essential for facilities requiring tight protection coordination and reduced fault severity, especially in high-current distributions. Feature → Business Impact → Application: Three-pole 800 A rating with 65 kAIC at 240 Vac and 50 kAIC at 480 Vac provides scalable protection for large motor loads and multi-feed circuits, enabling engineers to consolidate protection devices and simplify coordination studies. Feature → Business Impact → Application: Walking beam provisions facilitate easier wiring access and field tapping, improving maintenance efficiency and reducing labor time during terminal inspections and motor starter updates. Feature → Business Impact → Application: UL Listed certification supports compliance with NEC, NFPA, and regional safety requirements, giving procurement teams confidence in supplier reliability and reducing qualification time for new builds. Feature → Business Impact → Application: Compact Series C MDL frame dimensions (18 in L x 11 in W x 8 in H) with a 20 lb weight simplifies rack and panel planning while maintaining mechanical robustness, enabling more efficient enclosure layouts and better heat management in crowded panels.

FAQs

Ensure compatibility with the MDL frame and Series C backplane, then mount the frame-only unit in the designated three-pole slot. Use the walking beam provisions for terminal access, connect to the existing wiring per panel schematics, and verify voltage ratings (600 Vac / 250 Vdc) and 50/60 Hz operation before energizing. Follow the Eaton installation guidelines and UL listings for a safe, compliant retrofit.
Key specs include an 800 A amperage rating, 600 Vac and 250 Vdc voltage ratings, 65 kAIC interrupt rating at 240 Vac and 50 kAIC at 480 Vac, three-pole configuration, and T186 trip type within the Series C MDL frame. These values define protection for high-current loads and dictate coordination with upstream devices.
Yes. The 800 A rating, high interrupt capability (65 kAIC at 240 Vac / 50 kAIC at 480 Vac), and three-pole design make it appropriate for motor control centers and large feeder protection in industrial automation environments, while the frame-only design supports streamlined retrofits.
MDL3800FW01 carries UL Listed certification, ensuring alignment with recognized safety standards for electrical protection equipment. This supports compliance with NEC and related regional requirements, facilitating qualification during procurement and reducing approval time for installation in regulated facilities.
The product carries Eaton’s warranty terms: one year from the installation date or eighteen months from shipment, whichever occurs first. Regular inspection of terminals, torque checks, and adherence to the Series C and MDL frame specifications help maximize uptime and protect critical assets.
