Part of the PVGard series, the Eaton HFDDC2200L is a 200A, 2-pole molded case circuit breaker optimized for solar installations. This Series C F-Frame device utilizes fixed thermal and magnetic trip units to ensure precise overcurrent protection. The breaker mounts into Eaton Series C panelboards and solar combiner boxes, accommodating 4 AWG to 300 kcmil conductors via lug terminals. It features a 42 kAIC interrupting capacity at 600VAC and 250VDC, meeting stringent UL 489 requirements.
What types of panels or enclosures is the HFDDC2200L compatible with?
This F-frame breaker is designed for use in Eaton Series C panelboards. It is also frequently utilized in solar combiner boxes and industrial control panels due to its direct current capabilities.
What wire sizes do the factory lugs accept on this breaker?
The included line and load lugs accept wire gauges ranging from 4 AWG up to 300 kcmil. Always verify the conductor material and apply the manufacturer specified torque during installation.
Is this breaker suitable for photovoltaic or battery storage systems?
Yes, the HFDDC frame is specifically rated for direct current applications up to 250 VDC. This makes it highly suitable for solar installations, battery banks, and other DC power systems.
Can this Eaton breaker replace older Cutler-Hammer or Westinghouse models?
Yes, Eaton manufactures the Series C line to be fully backward compatible with legacy Cutler-Hammer and Westinghouse F-frame breakers that share the same physical dimensions and electrical specifications.
What safety precautions apply when installing this breaker in a DC circuit?
When installing in direct current systems, ensure all power sources such as photovoltaic arrays and battery storage are completely isolated. DC arcs are more difficult to extinguish than AC arcs, requiring strict adherence to lockout and tagout procedures before servicing.
