Part of the Series C family, this 20A F-Frame breaker provides reliable thermal-magnetic protection for commercial and industrial applications. It installs into Eaton switchboards and standalone enclosures using a standard unit-mount configuration with included line and load lugs. Rated for 65kAIC at 277VAC, it features SWD and HID ratings for lighting circuits, plus reverse feed capability. For modern upgrades, the Power Defense PDG11M0020TFFJ serves as a substitute.
What does the 'L' suffix in the HFD1020L catalog number signify?
The 'L' indicates that the breaker is supplied with factory-installed line and load terminals (lugs). These standard lugs accept 14 to 1/0 AWG copper or aluminum conductors.
Can the HFD1020L replace standard FD1020L or ED1020L breakers?
Yes. The HFD1020L shares the exact physical F-Frame dimensions as the FD1020L and ED1020L but offers a higher interrupting capacity (100kAIC at 240VAC). It can safely replace these lower-rated breakers in existing Series C panelboards and enclosures.
Which panelboards and enclosures are compatible with this breaker?
This unit mount breaker is designed for use in Eaton Series C panelboards, switchboards, and standalone F-Frame enclosures. It is an industrial molded case circuit breaker and is not compatible with standard residential loadcenters.
Is the HFD1020L rated for direct current (DC) systems?
Yes, this breaker is rated for use in DC circuits up to 125VDC with a maximum interrupting capacity of 10kAIC.
Does this breaker include ground fault or arc fault protection?
No. The HFD1020L features standard thermal magnetic trip functions (Long-Time and Instantaneous) for overload and short circuit protection. It does not provide GFCI or AFCI protection.
