Description
Built for industrial distribution, the Eaton EGE3100FFG is a 100A, 3-pole molded case circuit breaker. As part of the Series G EG-frame lineup, it utilizes fixed thermal and magnetic trip units to provide reliable long-time and instantaneous (LI) protection. This unit mount breaker integrates seamlessly into Eaton Pow-R-Line panelboards, Pow-R-Xpress enclosures, and MCCs. With an interrupt rating of 25kAIC at 480VAC, it features a trip-free mechanism and high-speed blow-open action.Specifications

Product FAQs
10 answersWhat does the FFG in the EGE3100FFG catalog number indicate?
In Eaton Series G nomenclature, the first F stands for a fixed thermal trip, the second F stands for a fixed magnetic trip, and the G indicates that standard line and load terminals (lugs) are included.
What is the difference between the Eaton EGE3100FFG and EGS3100FFG or EGH3100FFG breakers?
They share the same physical EG-frame footprint but have different interrupting capacities. The EGE is the standard tier, while the EGS and EGH offer higher interrupting ratings for systems with greater available fault current.
What is the modern replacement for the EGE3100FFG?
Eaton has transitioned the Series G EG-frame breakers to the newer Power Defense series. The direct equivalent for a 100A, 3-pole EGE breaker is found in the Power Defense Frame 1 (PDG1) lineup.
Can the EGE3100FFG be reverse fed?
Yes. Eaton EG-frame thermal-magnetic circuit breakers, including the EGE3100FFG, do not have line and load markings restricting power flow, making them suitable for reverse feed applications.
Does the EGE3100FFG come with mounting hardware and lugs?
Yes. Eaton Series G breakers in the EG frame size include standard line and load lugs as well as necessary mounting hardware directly from the factory, eliminating the need to order them separately.
Which panelboards are compatible with the EGE3100FFG?
This unit-mount breaker is designed for installation in Eaton Pow-R-Line panelboards, Pow-R-Xpress panels, Series G panelboards, and compatible commercial switchboards.
Can I use the EGE3100FFG in a motor control center (MCC)?
Yes, this breaker is suitable for use in Motor Control Centers (MCCs) and electrical assemblies manufactured by Eaton, Allen-Bradley, and Rockwell Automation, provided the enclosure is designed to accept EG-frame breakers.
Is the EGE3100FFG rated for DC voltage applications?
Yes, this breaker is rated for up to 250 VDC with an interrupting capacity of 10 kAIC. When used in 250 VDC systems, Eaton requires wiring two poles in series.
What type of trip unit is installed in the EGE3100FFG?
It features a non-interchangeable, fixed thermal-magnetic trip unit. It provides Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits, with no field adjustability.
Is the EGE3100FFG current limiting?
While the EG frame utilizes Eaton patented reverse loop contact design for high-speed blow-open action, the EGE3100FFG is a standard interrupting breaker. For true current-limiting performance in the EG frame, the EGC variant or an external current limiter module is required.
