Product FAQs
8 answersWhich panelboards and enclosures are compatible with the JGX3175FAG?
This JG-frame breaker is designed for use in Eaton Pow-R-Line panelboards, switchboards, motor control centers (MCCs), and standard Series G enclosures.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs accept wire sizes ranging from 8 AWG to 350 kcmil. They are rated for both copper and aluminum conductors.
What does the adjustable magnetic trip feature allow the user to do?
While the thermal overload protection is fixed at 175 amps, the adjustable magnetic trip allows electricians to set the instantaneous short-circuit response threshold to coordinate with other protective devices in the electrical system.
Is the JGX3175FAG suitable for direct current (DC) systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, providing an interrupting capacity of 50kA.
What distinguishes the JGX type from standard JG frame breakers?
The JGX designation indicates an ultra-high interrupting rating within the Eaton Series G family. It provides up to 200kA of fault clearing capacity at 480VAC, which is significantly higher than standard JG models.
How is the JGX3175FAG mounted within an electrical system?
This is a unit mount, feed-thru circuit breaker. It is typically bolted directly to a backpan or mounting plate within an enclosure or switchboard rather than plugging into a busbar system.
What safety considerations apply to wiring the lugs on this breaker?
When terminating the 8 AWG to 350 kcmil conductors, electricians must apply the exact torque specified on the breaker faceplate. Improper torque can lead to high resistance connections and thermal failure.
What does the FAG suffix indicate in the JGX3175FAG catalog number?
In the Eaton Series G nomenclature, F stands for a fixed thermal trip, A indicates an adjustable magnetic trip, and G means the breaker is supplied with both line and load lugs installed.
