Product FAQs
6 answersWhat makes the HFDDC2150L different from standard Series C breakers?
The DC designation indicates this breaker is part of Eaton's PVGard line. It is specifically engineered and tested for direct current applications up to 250VDC, making it ideal for solar photovoltaic systems, battery storage, and UPS installations.
What does the L at the end of the HFDDC2150L catalog number indicate?
The L signifies that the breaker is supplied complete with factory-installed line and load lugs. These terminals accommodate wire sizes from 4 AWG to 4/0 AWG.
Where is this F-Frame breaker typically installed?
It is designed for panel mounting in Eaton Series C panelboards, industrial switchboards, and solar combiner boxes that require a 2-pole, DC-rated disconnect or overcurrent protection device.
Is the HFDDC2150L interchangeable with other F-Frame breakers?
Yes, it shares the same physical dimensions and mounting footprint as standard Eaton Series C F-Frame breakers, allowing it to fit into existing F-Frame spaces within compatible enclosures.
Can this breaker be used in standard AC applications?
Yes. While it is optimized and certified for 250VDC solar and battery applications, it also carries a standard 600VAC rating with a 42kAIC interrupting capacity for conventional alternating current systems.
Does this breaker provide ground fault protection?
No, the HFDDC2150L features standard thermal-magnetic protection with long-time and instantaneous (LI) trip functions. It does not include integrated ground fault (LSIG) or equipment protection capabilities.
