Product details

The LE3250U33X is a Micrologic LSI trip unit for the PowerPacT L molded-case breaker family, rated for the 3.3S frame size and adjustable from 70 A to 250 A. It provides LSI protection — long-time, short-time, and instantaneous — for distribution and motor feeder circuits in commercial and industrial switchboards.

The 3.3S frame is a specific mechanical platform inside the PowerPacT L range. The LSI protection curve covers long-time delay (L), short-time delay (S), and instantaneous (I) — the same three functions a distribution panel needs for selective coordination downstream. The 70 A to 250 A adjustment range means one trip unit covers multiple breaker ratings; you set the pickup at commissioning. No ground-fault (LSIG) here — if the spec calls for GF, this isn't the one.

Deployment context

Mounts inside the PowerPacT L breaker case — it's not a standalone device. The trip unit plugs into the breaker's cradle, and the breaker itself bolts into a panelboard or switchboard. No DIN rail, no enclosure rating on the trip unit alone; the breaker's IP rating governs the installed assembly.

Frequently asked questions

Where can I buy LE3250U33X and how is it quoted?

We source the LE3250U33X through independent supply channels — new-old-stock and verified surplus. It is quoted to order against an RFQ; availability and current pricing are confirmed at quote time. No stock count or lead-time number is published here because the supply position changes with each lot.

What is the closest alternative to LE3250U33X in the PowerPacT family?

Schneider does not list a direct drop-in successor for the LE3250U33X. The current PowerPacT L trip units use the Micrologic 2.0/5.0/6.0 platform, which has a different mechanical interface and communication architecture. A panel re-fit or breaker replacement is typically required — not a simple trip-unit swap.

What is the LE3250U33X category code US10DE201103?

US10DE201103 is Schneider's internal category classification for this product line. It groups the PowerPacT L trip units in their catalog structure and is used for BOM mapping and cross-reference lookups within Schneider's system.
