B-LINE KT3225T – Frequently Asked Questions
1) What amperage and frame size is the Eaton Series C KT3225T trip unit?
The KT3225T is a 225A, three-pole trip unit built on the K-frame in Eaton's Series C molded case circuit breaker line. If your panel schedule calls for a K-frame at 225 amps on a three-phase circuit, this is the matching rating.
2) Is the KT3225T a thermal magnetic or purely electronic trip?
Trip type on the KT3225T is thermal magnetic. That matters if your spec calls for an adjustable electronic trip with settings for long time, short time and instantaneous, because a thermal magnetic unit does not give you that range of adjustment. Confirm the drawing calls for thermal magnetic before you order.
3) Will a 225A K-frame breaker unit fit the enclosure space I have?
Dimensions on the KT3225T are 6.9 inches long, 5.3 inches high and 4.3 inches wide, at 1.9 lb. Check those against the gutter space and mounting pan in your panel or enclosure before you commit, particularly depth behind a hinged door.
4) Can I use the KT3225T on a single-phase two-pole circuit?
No. It is a three-pole device, so it is intended for three-phase distribution. A two-pole single-phase load needs a two-pole K-frame breaker instead.
5) How do I confirm this is the exact Eaton part my electrician specified?
Order by the manufacturer part number KT3225T. The K denotes the K-frame, 3 the three poles and 225 the amp rating, all within Eaton's Series C molded case breaker line. Matching the full MPN is what keeps you from getting an adjacent amp rating in the same frame.
6) Where can I get the full electrical ratings for the KT3225T?
Eaton publishes a spec sheet for the KT3225T that is linked from the product information, and that document carries the voltage ratings, interrupting capacity and trip curve data your engineer will want for a short circuit study. The catalog data itself confirms 225A, three-pole, K-frame, thermal magnetic.
