Description
Built for heavy-duty commercial and industrial applications, the Eaton EGB3090FFB provides 90A of bolt-on circuit protection. Belonging to the Series G EG-frame family, it utilizes a fixed thermal-magnetic trip unit to achieve an 18 kAIC rating at 480VAC. This breaker mounts securely into Eaton Pow-R-Line panelboards, offering current-limiting performance and reverse feed capabilities. For modern upgrades, this unit has been replaced by the PDG13C0090TFFJ with a mounting kit.Specifications

Product FAQs
6 answersWhich Eaton panelboards are compatible with the EGB3090FFB?
This EG-frame breaker is designed for use in Eaton Pow-R-Line panelboards, including the PRL1a, PRL2a, PRL3a, and PRL4 series.
Can the EGB3090FFB be reverse fed?
Yes. Eaton EG-frame breakers are UL listed for reverse feed applications. They do not have specific line and load markings, allowing power to be supplied from either the top or bottom terminals.
What does the FFB suffix mean in the EGB3090FFB catalog number?
The FFB suffix indicates the breaker is equipped with a fixed thermal and fixed magnetic trip unit, and it utilizes a bolt-on mounting configuration for panelboard installations.
Are there higher interrupting capacity alternatives to the EGB3090FFB?
Yes. If your application requires a higher fault current rating than the standard EGB series provides, Eaton offers the EGE, EGS, EGH, and EGC series breakers which share the exact same EG-frame footprint.
Can I adjust the trip settings on the EGB3090FFB?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory-set for 90 amps and cannot be modified in the field.
Can the EGB3090FFB be used in direct current (DC) systems?
Yes. While primarily installed in AC panelboards, this thermal-magnetic breaker is also UL listed for DC applications up to 250VDC.
