B-LINE JDC3100 – Frequently Asked Questions
1) What is the interrupting rating of the JDC3100 breaker at 480V?
100 kAIC at 480 Vac, and 200 kAIC at 240 Vac. The JDC suffix is Eaton's high interrupting J-frame class, so this is the one to specify where the available fault current at the service is high enough that a standard JD would not hold. Check the calculated fault current at your panel against those two numbers before you commit.
2) Is the JDC3100 an adjustable trip breaker or a fixed trip?
Fixed. The JDC3100 uses a fixed thermal, fixed magnetic trip unit, so there is no dial to set the instantaneous or long-time pickup. If your coordination study calls for an adjustable magnetic setting, you need a different trip type in the J-frame line rather than this one.
3) Will a J-frame JDC3100 fit the space I have in my panel or enclosure?
Dimensions are 10 in. by 4.13 in. by 4.06 in., and it weighs 14.25 lb. That is standard Eaton J-frame footprint. The weight is worth planning for on a panel-mount or bracket install, since it is heavier than the typical branch breaker and wants proper support.
4) Does the JDC3100 come complete, or do I have to order the trip unit separately?
It ships as a complete breaker, meaning the frame and the fixed thermal-magnetic trip unit come as one assembled 100A three-pole unit. There is no separate rating plug or trip unit to specify, which is what distinguishes it from the electronic-trip J-frames that are ordered as frame plus trip.
5) What is the difference between an Eaton JD and a JDC breaker?
Same J-frame, different interrupting class. The JDC is the high-interrupting version, and on the JDC3100 that means 200 kAIC at 240 Vac and 100 kAIC at 480 Vac. A standard JD carries a lower AIC at the same voltages. If your fault current study pushed the required AIC above what the JD holds, the JDC is the direct step up in the same frame size.
6) What part number do I order for a 100 amp three-pole Eaton Series C J-frame breaker?
JDC3100. The catalog number reads as JDC frame class, 3 poles, 100 amps, and it is part of the Eaton Series C molded case line. That is the full manufacturer part number, no suffix needed for the standard unit.
7) Can the JDC3100 be used on a DC circuit?
Yes, it carries a 250 Vdc rating alongside 600 Vac. On DC the three poles are typically applied in series to reach the rated voltage, so confirm the connection arrangement your application requires before wiring it in.
