Description
Designed for commercial power distribution, the Eaton EGH1030FFB is a 1-pole, 30A molded case circuit breaker. It provides essential long-time and instantaneous (LI) protection for facility applications. This bolt-on breaker mounts into Eaton Series G panelboards. The PDG11M0030TFFJ serves as a substitute but requires a mounting kit. With an interrupting capacity of 100kAIC at 240VAC and 65kAIC at 277VAC, it handles high fault currents safely and features a patented blow-open action.Specifications

Product FAQs
7 answersWhat panelboards accept the Eaton EGH1030FFB circuit breaker?
The EGH1030FFB is an EG-frame breaker designed specifically for installation in Eaton Series G panelboards and compatible industrial enclosures. It is not interchangeable with standard residential load centers.
Can the EGH1030FFB be used in direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is certified for 125VDC applications with a 42kAIC interrupting rating, allowing it to be used in control panels and industrial DC circuits.
What type of trip unit is equipped on the EGH1030FFB?
This breaker features a non-interchangeable, fixed thermal and fixed magnetic trip unit. The "FFB" in the catalog number designates this fixed configuration along with its standard bolt-on terminal design.
What wire size is required for the lugs on the EGH1030FFB?
The factory-installed lugs accommodate a wide range of wire sizes from 14 AWG up to 1/0 AWG. Both copper (Cu) and aluminum (Al) conductors are permitted.
Is the EGH1030FFB suitable for reverse feed applications?
Yes, Eaton Series G EG-frame circuit breakers, including the EGH1030FFB, are suitable for reverse feed applications.
What does the "H" in the EGH1030FFB catalog number indicate?
In Eaton's Series G nomenclature, the "H" designates a high interrupting capacity tier for the EG frame. This allows the breaker to safely interrupt up to 100kAIC at 240VAC and 65kAIC at 277VAC.
Is there a newer replacement for the EGH1030FFB?
Yes, Eaton's Power Defense series is the modern replacement for Series G breakers. The PDG1 (Power Defense Frame 1) series serves as the direct upgrade path for EG-frame breakers like the EGH1030FFB.
