Product FAQs
6 answersCan the Eaton JDC3250 replace an older Westinghouse JDC3250 breaker?
Yes. Eaton acquired the Westinghouse distribution equipment division and continued manufacturing the Series C line. The Eaton JDC3250 is a direct replacement for legacy Westinghouse JDC3250 breakers, sharing the same physical dimensions, mounting footprint, and electrical ratings.
What is the difference between the Eaton JD, HJD, and JDC circuit breakers?
The prefix indicates the interrupting capacity (AIC) at 480VAC. The JD frame offers standard interrupting ratings, the HJD provides high interrupting capacity, and the JDC is the ultra-high interrupting, current-limiting version rated at 100kA at 480VAC.
What lug kit is standard for the JDC3250 circuit breaker?
The standard line and load lug kit for the 250A J-frame is the TA250KB. It accepts aluminum or copper wire ranging from 8 AWG to 350 kcmil.
How is the magnetic trip adjusted on the JDC3250?
The instantaneous magnetic trip is adjusted using a dial on the face of the trip unit. For a 250A Series C breaker, the magnetic pickup range can typically be set between 5 and 10 times the continuous current rating, which corresponds to 1250A to 2500A.
Is the JDC3250 suitable for reverse-feed applications?
Yes. Series C J-frame thermal-magnetic circuit breakers without interchangeable trip units, like the JDC3250, are suitable for reverse-feed applications.
What does the LI trip function code mean on this breaker?
LI stands for Long-Time and Instantaneous protection. The Long-Time function provides thermal overload protection with an inverse time delay, while the Instantaneous function provides immediate magnetic tripping during short-circuit faults.
