Product FAQs
7 answersWhat equipment is the JGS3175FAG breaker compatible with?
This JG-frame breaker is designed for installation in Eaton Series G panelboards, switchboards, and motor control centers. It is also compatible with select Allen-Bradley and Rockwell Automation enclosed controls.
Are the trip settings adjustable on the JGS3175FAG?
Yes, this breaker is equipped with a fixed thermal and adjustable magnetic (LI) trip unit. The thermal overload is fixed at 175A, but the instantaneous magnetic trip threshold can be adjusted for selective coordination with other protective devices or specific motor loads.
What does the FAG suffix indicate in the JGS3175FAG catalog number?
The FAG suffix designates that the breaker is a complete, factory-assembled unit featuring a fixed thermal and adjustable magnetic trip unit. It also indicates that standard line and load lugs, along with metric mounting hardware, are included.
What wire gauge is supported by the standard lugs on this JG-frame breaker?
The factory-installed line and load lugs on this 175A breaker accept copper or aluminum conductors ranging from 4 AWG to 350 kcmil.
How does the JGS series differ from other Eaton Series G JG-frame breakers?
The S in the JGS prefix indicates a standard interrupting tier. This provides a 35 kAIC rating at 480V AC and 85 kAIC at 240V AC. Other tiers, such as JGE or JGH, offer lower or higher interrupting capacities for the same 250A maximum frame size.
Is the JGS3175FAG configured for unit-mount or plug-on installations?
This is a unit-mount, free-standing breaker designed for feed-thru applications. It does not have plug-on jaws for busbar systems and must be hardwired or bolted directly to the chassis or mounting pan.
Can the JGS3175FAG be used in DC applications?
Yes, this thermal-magnetic breaker is rated for DC applications up to 250V DC, providing an interrupting capacity of 22 kAIC.
