Product FAQs
8 answers
What enclosures and panels are compatible with the JDC3200?
This breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It is also compatible with legacy Westinghouse panelboards that accept J-Frame breakers.
Can the Eaton JDC3200 replace an older Westinghouse JDC3200?
Yes. Eaton acquired the Westinghouse distribution equipment line, so the modern Eaton or Cutler-Hammer JDC3200 is a direct replacement for the legacy Westinghouse JDC3200 circuit breaker.
What is the difference between the JD, HJD, and JDC breakers?
They share the same physical J-Frame dimensions but have different interrupting capacities. The JDC is the highest-rated version, offering up to 100kAIC at 480VAC, compared to 65kAIC for the HJD and 35kAIC for the standard JD.
How do I adjust the trip settings on the JDC3200?
The JDC3200 features a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic trip can be adjusted using the dial on the face of the trip unit.
What wire sizes do the standard lugs on this breaker accept?
The standard factory lugs accept aluminum or copper wire ranging from 8 AWG to 350 kcmil.
What does the "C" in JDC stand for?
In the Eaton Series C nomenclature, the "C" indicates that it is a current limiting circuit breaker with an ultra-high interrupting capacity, rated up to 200kAIC at 240VAC and 100kAIC at 480VAC.
Is this a plug-in or bolt-on circuit breaker?
The JDC3200 is a unit mount circuit breaker. It is designed to be bolted directly to a backpan or mounting plate and wired using cable-in and cable-out lug connections, rather than plugging onto a busbar.
What safety precautions should be taken before installing this breaker?
Always ensure the panel or switchboard is completely de-energized before installation. Verify the absence of voltage using a properly rated multimeter, and follow all local electrical codes and lockout/tagout procedures.
