Product FAQs
8 answersWhat enclosures or panels accept the JDC3175?
The JDC3175 is a unit-mount Series C J-Frame breaker designed for Eaton switchboards, motor control centers, and legacy Westinghouse panelboards.
Can this replace an older Westinghouse JDC3175?
Yes. Eaton acquired Westinghouse's distribution equipment division, and the Series C JDC3175 is a direct, drop-in replacement for the legacy Westinghouse model with the same catalog number.
What is the standard lug kit for the JDC3175?
The standard line and load lug kit for this 175A J-Frame breaker is the TA250KB, which accepts 8 AWG to 350 kcmil aluminum or copper wire.
What does the C in JDC3175 indicate?
The C designates the ultra-high interrupting capacity version of the Series C J-Frame. While standard JD breakers offer 65kAIC at 480VAC, the JDC provides 100kAIC at 480VAC and 200kAIC at 240VAC.
How does the magnetic trip adjustment work on the JDC3175?
This breaker features a fixed thermal element for overload protection and an adjustable magnetic element for short-circuit protection. The magnetic pickup can be dialed in to match specific load requirements and coordination studies.
Can the JDC3175 be reverse fed?
Yes. Standard thermal-magnetic Series C J-Frame breakers like the JDC3175 do not have Line and Load markings, making them suitable for reverse-feed applications.
Does the JDC3175 provide ground fault protection?
No. The JDC3175 features an LI (Long-Time and Instantaneous) trip unit. If ground fault protection is required, you will need an LSIG electronic trip unit or an external ground fault relay system.
Is there a difference between the JD3175 and JDC3175?
Yes, the primary difference is the interrupting rating. The JD3175 is rated for 65kAIC at 480VAC, whereas the JDC3175 is rated for 100kAIC at 480VAC. They share the same physical dimensions and mounting footprint.
