Product FAQs
8 answersIs there a direct replacement for the EGH2020FFG?
Yes, Eaton is transitioning the Series G line to the newer Power Defense series. The direct replacement for this breaker is the Power Defense catalog number PDG12M0020TFFJ.
What types of equipment can the EGH2020FFG be installed in?
This EG-frame breaker is designed for use in Eaton Series G enclosures, panelboards, and switchboards. It utilizes a unit mount, feed-thru design that bolts directly to the mounting surface or backpan.
What does the FFG suffix mean in the EGH2020FFG catalog number?
In Eaton's Series G nomenclature, FF indicates that the breaker has a fixed thermal and fixed magnetic trip unit. The G signifies that both line and load terminals are included from the factory.
Can I adjust the trip settings on this circuit breaker?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip thresholds are factory set and cannot be altered in the field.
What are the wire size requirements for the factory-installed lugs?
The included line and load lugs accept 14 AWG to 1/0 AWG copper or aluminum conductors. Always ensure the wire is torqued to the specifications printed on the breaker faceplate during installation.
Is this breaker suitable for direct current (DC) applications?
Yes, the EGH2020FFG is rated for up to 250VDC with an interrupting capacity of 42kA. This makes it suitable for specific DC control circuits, battery systems, or solar applications requiring a 2-pole disconnect.
What is the difference between the EGH and EGB series breakers?
The primary difference is the interrupting capacity. The EGH series is a high-interrupting breaker, offering 65kAIC at 480VAC, whereas the standard EGB series offers a lower interrupting rating of 18kAIC at 480VAC for the same physical frame size.
Does this breaker plug into a busbar?
No, the EGH2020FFG is a unit mount breaker. It must be bolted directly to the enclosure backpan or mounting surface and wired using the provided feed-thru lugs.
