Product FAQs
6 answersCan the Eaton JDC3225 replace older Westinghouse JDC breakers?
Yes. Because Eaton acquired the Westinghouse distribution equipment division, the Series C JDC3225 is a direct, drop-in replacement for legacy Westinghouse JDC breakers of the same 225A rating and 3-pole configuration.
What distinguishes the JDC3225 from a standard JD3225 breaker?
The JDC3225 is the ultra-high interrupting capacity version of the Series C J-frame. It provides up to 200kAIC at 240VAC and 100kAIC at 480VAC, which is significantly higher than the standard JD frame, while maintaining the exact same physical dimensions and mounting footprint.
What wire types are supported by the standard lugs on the JDC3225?
The standard lugs (catalog number TA250KB) are dual-rated for both aluminum and copper conductors. They accept wire sizes ranging from 4 AWG to 350 kcmil.
How does the adjustable magnetic trip function operate on the JDC3225?
This breaker uses a thermal-magnetic trip unit with a fixed thermal element for standard overload protection and an adjustable magnetic element. The magnetic dial allows installers to adjust the instantaneous short-circuit trip threshold, which is useful for coordinating with downstream devices or handling motor inrush currents.
What types of enclosures accept the JDC3225 breaker?
This unit-mount, feed-thru breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It is also fully backward compatible with legacy Westinghouse enclosures built for J-frame breakers.
Does the JDC3225 provide ground fault protection?
No. The JDC3225 is a standard thermal-magnetic breaker providing overload and short-circuit protection (LI trip functions). It does not include built-in equipment ground fault protection (LSIG) or personnel ground fault circuit interruption (GFCI).
