B-LINE KT3250T – Frequently Asked Questions
1) What amperage and how many poles is the Eaton KT3250T trip unit?
The KT3250T is rated 250A and is a three-pole unit, so it is for three-phase service. If your breaker frame is feeding a single-phase two-wire load or needs a different ampere rating, this is not the right part number.
2) Will the KT3250T fit a J-frame or L-frame Eaton breaker?
No. The KT3250T is a K-frame trip unit in the Eaton Series C line, and frames are not interchangeable. For a J-frame or L-frame breaker you need the trip unit built for that frame and ampere rating.
3) Is the KT3250T a complete circuit breaker or just the trip unit?
It is the trip unit only, the sensing and tripping assembly for an Eaton Series C K-frame molded case breaker. You still need the matching breaker frame it mounts into; ordering this alone will not give you a usable breaker.
4) How much room do I need in the panel for the KT3250T trip unit?
Plan on a footprint of 6.9 by 4.4 inches with a height of 5.4 inches, and about 1.9 lb of weight. That is the space to confirm against your enclosure or panelboard cutout before you commit.
5) Where can I get the manufacturer specification sheet for the KT3250T?
Eaton publishes a spec sheet for the KT3250T, and it is linked directly from the product information for this trip unit. That document is the place to confirm interrupting ratings and the exact frame it mounts into for your installation.
