Product FAQs
7 answersWhat enclosures or panelboards is the LGS3250FAG compatible with?
This LG-frame breaker is designed for use in Eaton Series G panelboards, switchboards, and motor control centers (MCCs).
How does the trip unit operate on the LGS3250FAG?
It features a thermal-magnetic trip unit with a fixed thermal setting for long-time overload protection and an adjustable magnetic setting for instantaneous short-circuit protection.
What does the "FAG" suffix mean in the LGS3250FAG catalog number?
In Eaton Series G nomenclature, "FA" indicates a fixed thermal and adjustable magnetic trip unit, while "G" signifies that standard line and load lugs are included.
What does the "S" in the LGS3250FAG part number represent?
The "S" indicates the interrupting capacity tier. The LGS tier provides 50 kAIC at 480VAC, which sits between the standard LGE (35 kAIC) and high-interrupting LGH (65 kAIC) tiers.
What wire sizes do the standard lugs on this breaker accept?
The included line and load lugs accept 2/0 AWG to 500 kcmil aluminum or copper wire.
What does "Metric" mounting indicate for this LG-frame breaker?
It means the breaker is equipped with metric-threaded end caps and requires metric hardware for base mounting in your enclosure.
What does a feed-thru connection mean for the LGS3250FAG?
A feed-thru connection means the breaker is designed to be wired directly in-line with the circuit using the provided line and load lugs, rather than plugging into a busbar system.
