Eaton LA3200PT – Frequently Asked Questions

1) Is the Eaton LA3200PT a complete circuit breaker or just the trip unit?
It is the trip unit only. The LA3200PT is the interchangeable thermal-magnetic trip unit that installs into an Eaton Type LA Tri-Pac frame breaker. You do not get a breaker frame, so if you are building a new installation from scratch you need the LA Tri-Pac frame as well. If you are re-rating or servicing a breaker that is already in the panel, this is the part that changes the rating.
2) What breaker frame does the LA3200PT trip unit fit?
The Eaton Type LA Tri-Pac frame, and only that frame. The trip unit is coded LA and is part of Eaton's Tri-Pac interchangeable trip system, so it will not drop into a different Eaton frame family or another manufacturer's breaker. Confirm the existing breaker is an LA Tri-Pac before ordering.
3) Will a 200A LA trip unit work on a 480V three-phase feeder?
Yes. The trip unit is rated 600 Vac, which covers 480Y/277 and 480 V delta three-phase systems, and it is a three-pole unit for balanced three-phase circuits. It also carries a 250 Vdc rating for DC applications.
4) What does the 1000-2000A magnetic trip range mean on a 200A trip unit?
That is the instantaneous (short-circuit) pickup, not the continuous rating. The unit carries 200A continuously on thermal overload protection, and its magnetic element is adjustable from 1000A to 2000A, roughly 5x to 10x the 200A rating. That adjustment is what lets you ride through motor inrush on a three-phase motor or feeder circuit without nuisance tripping while still clearing a genuine fault.
5) Can I change the amp rating of an existing LA Tri-Pac breaker instead of replacing the whole breaker?
That is exactly what the Tri-Pac design is for. The trip unit is field-interchangeable, so on an existing LA Tri-Pac frame you swap the trip unit to re-rate the breaker rather than pulling and replacing the entire breaker. The LA3200PT sets that frame at 200A, three-pole. For any other amperage you order the matching LA trip unit instead.
6) Is a 200 kAIC interrupt rating enough for a high fault-current service?
200 kAIC at 600 Vac is at the top end of what molded-case breaker assemblies are rated for, so it suits service-entrance and industrial switchgear locations where the available fault current is high. The number you need to beat is the available fault current from your utility or engineered short-circuit study at that point in the system.
7) Is the Eaton LA Tri-Pac trip unit UL listed for branch circuit protection?
It is UL 489 certified. UL 489 is the standard for molded-case circuit breakers used as branch-circuit and feeder overcurrent protection, which is what inspectors and institutional specs call for on panelboard and switchgear work. That is the only listing stated for this unit.
8) How much room do I need in the panel for the LA3200PT?
Plan for 5.3 in wide by 5.3 in high with 10.1 in of depth. The depth is the number that usually decides it, so check the gutter and cover clearance behind the deadfront before you commit, particularly in older switchgear sections.
9) What is the exact Eaton part number for the 200A three-pole LA Tri-Pac trip unit?
Eaton LA3200PT. In the numbering, LA is the frame family, 3 is the pole count and 200 is the amp rating, so a distributor or MRO storeroom can cross-check it against the nameplate on the breaker being serviced.
