Product FAQs
7 answersWhich panelboards are compatible with the JGC3100FAG?
This JG-frame breaker is designed for unit mounting in Eaton Pow-R-Line 3a and Pow-R-Line 4 panelboards, Series G panelboards, as well as compatible switchboards and motor control centers.
What does the FAG suffix mean in the JGC3100FAG catalog number?
In Eaton Series G nomenclature, the F indicates a fixed thermal trip, the A indicates an adjustable magnetic trip, and the G signifies that standard line and load lugs are factory installed.
What is the difference between the JGC3100FAG and the JGH3100FAG?
The difference is the short-circuit interrupting capacity. The JGC3100FAG features a high interrupting rating of 100 kAIC at 480VAC, whereas the JGH3100FAG is rated for 65 kAIC at 480VAC. Both share the same physical JG-frame footprint and trip unit.
Is the trip unit on the JGC3100FAG adjustable?
The thermal overload protection is fixed at 100 amps, but the magnetic short-circuit trip is adjustable. This allows electricians to fine-tune the instantaneous trip response for specific coordination requirements.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed line and load lugs accept aluminum or copper conductors ranging from 4 AWG to 350 kcmil.
Can the JGC3100FAG be reverse fed?
Yes. Eaton Series G thermal-magnetic circuit breakers are suitable for reverse-feed applications, provided they are not specifically marked with line and load designations on the breaker face.
Are Eaton JGC breakers rated for direct current (DC) systems?
Yes, the JGC3100FAG carries a DC rating for systems up to 250VDC, providing a 42 kAIC interrupting capacity for direct current applications.
