Rated for 14 kAIC at 277V, the Eaton EHD1100 provides robust overcurrent protection for commercial and industrial environments. This single-pole, 100A molded case circuit breaker features fixed thermal and magnetic trip units within a compact F-Frame footprint. It installs into Series C panelboards and is HACR rated for HVAC applications. Note that this legacy model is officially replaced by the Power Defense PDG21F0100TFFJ, which requires a retrofit kit for older enclosures.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the EHD1100 circuit breaker?
The EHD1100 is an F-frame bolt-on breaker designed for use in Eaton Series C panelboards, including Pow-R-Line 3a (PRL3a) and Pow-R-Line 4 (PRL4) distribution panels.
Can I use an FD1100 or HFD1100 in place of the EHD1100?
Yes. The FD1100 and HFD1100 are higher interrupting capacity versions of the same 1-pole 100A F-frame breaker. They share the exact same physical dimensions and mounting hardware as the EHD1100.
What wire gauge is supported by the standard lugs on the EHD1100?
The standard line and load lugs for this 100A breaker accept copper or aluminum conductors ranging from 14 AWG up to 1/0 AWG.
Is the EHD1100 suitable for direct current (DC) circuits?
Yes, this thermal-magnetic breaker is rated for 125VDC applications with a 10kAIC interrupting capacity, making it suitable for specific DC control or distribution circuits.
Can the EHD1100 be reverse fed?
Yes, standard thermal-magnetic Series C F-frame breakers like the EHD1100 are suitable for reverse-feed applications, as they do not contain electronic trip units that restrict power flow direction.
Does the EHD1100 include ground fault or arc fault protection?
No, the EHD1100 features a standard thermal-magnetic trip unit (LI) for basic overload and short-circuit protection. It does not provide GFCI or AFCI protection.
