Eaton LGS3250AAG – Frequently Asked Questions

1) Will the Eaton LGS3250AAG breaker hold up on a 480V system with high available fault current?
The Eaton Series G LG-frame three-pole breaker, model LGS3250AAG, is rated 50 kAIC at 480 Vac. If your coordination study shows available fault current at or below 50 kA at 480 Vac, it is within rating. Above that, you need a higher interrupting rating or series-rated combination.
2) Can I adjust the trip settings on the Eaton LGS3250AAG, or is it a fixed trip breaker?
Both trip elements adjust. The LG-frame 250 A three-pole unit uses an adjustable thermal element for overload and an adjustable magnetic element for instantaneous short-circuit pickup, so you can tune it to the connected load and coordinate with upstream and downstream devices instead of living with a fixed curve.
3) Does the Eaton LGS3250AAG come as a complete breaker, or do I have to order a trip unit and terminals separately?
It ships as a complete breaker. The LG-frame frame type is listed as a complete breaker, with line and load terminals included and metric mounting hardware supplied. You are not specifying a separate interchangeable trip unit for this one.
4) Can I use this Eaton breaker to feed a rooftop air conditioning unit or refrigeration equipment?
Yes. The Series G LG-frame 250 A breaker is HACR rated, which is what lets it serve heating, air conditioning and refrigeration branch circuits where the nameplate calls for an HACR type breaker. It is also UL Listed.
5) What are the physical dimensions of the Eaton LG-frame 250A three-pole breaker for panel layout?
The LG-frame three-pole unit measures 5.48 in height, 5.48 in width and 4.09 in depth. Use those figures to check pocket space and gutter clearance in the panelboard, switchboard or control enclosure before you commit to the layout.
6) I only need to protect a two-wire 240V feeder. Is the LGS3250AAG the right choice?
No. This one is built three-pole for three-phase distribution, so all three poles trip together. For a single-phase two-wire or three-wire feeder you want a one- or two-pole breaker instead. Ordering a three-pole for a single-phase circuit just wastes a pole and panel space.
7) What part number do I order for the Eaton Series G 250 amp three-pole LG-frame breaker?
Order Eaton catalog number LGS3250AAG. That is the Series G LG-frame, three-pole, 250 A complete breaker with adjustable thermal-magnetic trip and 50 kAIC at 480 Vac.
8) Will this Eaton breaker work on a 50 Hz system for imported equipment?
Yes. The Series G LG-frame breaker carries a 50 to 60 Hz frequency rating, so it applies on both 60 Hz North American distribution and 50 Hz systems feeding imported machinery.
