Product FAQs
7 answersWhat does the FFG suffix indicate on the EGS2050FFG catalog number?
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 lugs are factory installed. These lugs accept 14 to 1/0 AWG copper or aluminum wire.
What types of panels and enclosures is the EGS2050FFG compatible with?
It is designed for use in Eaton Series G enclosures, switchboards, motor control centers (MCCs), and OEM control panels that accommodate an EG-frame footprint.
Can the EGS2050FFG be used in direct current (DC) systems?
Yes, this breaker is rated for 125/250VDC applications with an interrupting capacity of 35kA, making it suitable for specific DC control circuits.
How is the EGS2050FFG mounted in a panel?
It is a unit mount, feed-thru circuit breaker. This means it bolts directly to the backpan of the enclosure or panel rather than plugging onto a busbar.
Does the EGS2050FFG offer adjustable trip settings for selective coordination?
No, it features a fixed thermal and fixed magnetic trip unit. The overload and short-circuit thresholds are factory set and cannot be modified in the field.
Is the Eaton EGS2050FFG a current-limiting circuit breaker?
Yes, as part of the Eaton Series G family, it features a patented contact design with high-speed blow-open action, providing current-limiting performance to minimize fault damage.
What does the LI trip function code mean for this breaker?
The LI designation indicates that the breaker provides Long-Time (overload) and Instantaneous (short-circuit) protection. Both of these protection parameters are fixed on the EGS2050FFG.
