Product FAQs
6 answersWhich panelboards are compatible with the EGH3100FFB circuit breaker?
This EG-frame breaker is designed for installation in Eaton Pow-R-Line panelboards and switchboards that accept bolt-on Series G breakers.
What wire sizes and materials are accepted by the standard lugs on the EGH3100FFB?
The factory-installed pressure-type terminals accept 14 AWG to 1/0 AWG copper or aluminum wire.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the EGH3100FFB features fixed thermal and fixed magnetic trip settings, providing standard long-time and instantaneous (LI) protection without field adjustability.
What does the FFB suffix mean in the EGH3100FFB catalog number?
The FFB suffix designates that this is a complete breaker equipped with fixed thermal and fixed magnetic trip units, and it utilizes a bolt-on mounting configuration for the load center or panelboard.
Is the EGH3100FFB suitable for direct current (DC) systems?
Yes, this Series G breaker is rated for DC applications up to 250VDC, making it suitable for specific industrial DC control circuits and power distribution.
Can the EGH3100FFB be installed on a 600V ungrounded delta system?
No. This breaker carries a 600Y/347VAC slash rating, meaning it is only approved for solidly grounded wye systems where the line-to-ground voltage does not exceed 347V. It must not be used on 600V ungrounded or corner-grounded delta systems.
