Product FAQs
8 answersWhat panelboards are compatible with the Eaton EGH3050FFB?
This EG-frame breaker is designed for use in Eaton Pow-R-Line panelboards. It features a bolt-on mounting style for a secure, direct connection to the panel bus.
What does the H in the EGH3050FFB catalog number signify?
The H indicates a high interrupting rating within the Series G EG-frame family. It provides up to 100kAIC at 240VAC and 65kAIC at 480VAC, making it suitable for commercial and industrial systems with high available fault currents.
What wire sizes are accepted by the terminals on this 50A breaker?
The standard lugs on the EGH3050FFB accept 14 AWG through 1/0 AWG copper or aluminum conductors. Always torque the terminal connections to the specifications printed on the breaker label.
Can the trip settings on the EGH3050FFB be adjusted in the field?
No. The FF in the catalog number indicates that this breaker has fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip functions are factory-set and cannot be modified.
How does the EGH3050FFB handle high-level short circuits?
Eaton Series G breakers utilize a patented contact design with high-speed blow-open action. This rapidly clears faults, providing superior protection and contributing to its high 65kAIC rating at 480VAC.
Is the EGH3050FFB the same as a Cutler-Hammer breaker?
Yes. Eaton acquired Cutler-Hammer, and they manufacture the Series G EG-frame breakers. An Eaton EGH3050FFB is the exact same product and a direct replacement for a legacy Cutler-Hammer breaker with the identical catalog number.
What does the B at the end of the EGH3050FFB part number mean?
The B suffix indicates that this breaker has a bolt-on connection type. This is required for secure installation into compatible Eaton Pow-R-Line panelboards.
Does this breaker provide ground fault protection?
No, the EGH3050FFB is a standard thermal-magnetic circuit breaker providing long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include built-in ground fault (GFCI) or equipment protection (GFEP) features.
