What does the "FFG" suffix indicate in the EGB3050FFG catalog number?
The "FFG" suffix indicates that the breaker has a fixed thermal and fixed magnetic trip unit (FF) and comes standard with both line and load lugs installed (G).
What wire sizes are accepted by the standard lugs on the EGB3050FFG?
The standard line and load lugs accept copper or aluminum (Cu/Al) wire sizes ranging from 14 AWG up to 1/0 AWG.
Can the EGB3050FFG be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, providing an interrupting capacity of 10 kAIC.
What is the difference between the Eaton EGB, EGE, EGS, and EGH circuit breakers?
These prefixes indicate the interrupting capacity of the Eaton Series G EG-frame breakers. The EGB is the standard tier, rated at 18 kAIC at 480VAC. The EGE, EGS, and EGH models offer progressively higher interrupting ratings for systems with higher available fault currents.
Are the trip settings adjustable on the EGB3050FFG?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
