About Schneider Electric LUB12
Schneider Electric publishes LUB12 as a power base in the TeSys Ultra combination motor starter range, described as a 3-pole power base with a conventional free air thermal current (Ith) of 12 A and screw clamps control connection. Schneider's regional catalogues also describe it as a non-reversing power base rated 12 A / 690 V with a 1 NO + 1 NC contact arrangement.
TeSys Ultra starters are modular: the LUB power base pairs with an LUC control unit, and the two are separate commercial references. A listing for a control unit is therefore not a listing for this base, and the current rating in the reference is not interchangeable — LUB12 is not LUB32.
Schneider positions the modular structure as a way to carry out quick maintenance and to reach detailed information for each motor starter in an installation. Confirm the base rating, control connection type and any accessory you need on the supplier's own listing before ordering.

Common formatting variations
Suppliers, ERP systems, and handwritten work orders do not always write the number the same way. These are the forms worth trying — or ruling out — when a search returns nothing:
- LUB12 — the commercial reference as Schneider Electric publishes it
- LUB 12 — a space inserted in handwritten work orders and spreadsheets
- LUB32 / LUB120 — different ratings in the same LUB base family, not this reference
- LUCA / LUCB / LUCC control units — the matching control half, ordered separately
How to search for LUB12
- Search the exact catalog number, LUB12, rather than a description.
- Confirm the manufacturer is Schneider Electric on the listing you open.
- Compare the supplier information returned side by side.
- Verify specifications and compatibility directly with the selected supplier before ordering.

Frequently asked questions
Where can I search for LUB12?
Enter LUB12 in PartVista's search field. PartVista checks the supplier sources connected to the app and shows the matching listings together with the link, listed price and stated availability.
What is LUB12?
Schneider Electric lists it as a TeSys Ultra power base: 3-pole, 12 A conventional free air thermal current, 690 V, 1 NO + 1 NC, with screw clamps control connection, for one direction of rotation.
Does LUB12 include a control unit?
No. In the TeSys Ultra range the LUB power base and the LUC control unit are separate commercial references, so check what the supplier's listing actually ships.
Is LUB12 the same as LUB32?
No. The number is the current rating of the base, so they are different references. Search the full reference and confirm the rating on the listing.
Does PartVista sell LUB12?
No. PartVista searches supplier listings and lets you save the part; the purchase happens with the supplier you choose.
Can listed prices and availability change?
Yes. Motor-starter components move in and out of stock and prices update on supplier schedules. Confirm price, condition, package quantity and lead time before ordering.
