Product FAQs
6 answers
What is the difference between the HJD3200 and the standard JD3200?
The HJD3200 is the high-interrupting capacity version of Eaton's Series C J-Frame. It delivers a 65kA short-circuit rating at 480VAC, while the standard JD3200 is rated for 35kA at 480VAC. Both share the exact same physical footprint and panelboard compatibility.
Which lug kit comes standard with this 200A breaker?
This unit is typically equipped with TA250KB line and load lugs. These dual-rated aluminum/copper terminals accept wire gauges from 4 AWG up to 350 kcmil.
What enclosures and equipment will accept the HJD3200?
It is designed for unit-mount installation in Eaton Series C panelboards, motor control centers, and switchboards. It is also backward compatible with legacy Westinghouse enclosures built for standard J-Frame breakers.
How does the adjustable magnetic trip function operate on this model?
The thermal overload protection is fixed at 200A, but the instantaneous magnetic trip is adjustable. This allows you to dial in the short-circuit pickup threshold, typically between 1000A and 2000A, to ensure proper selective coordination with downstream devices.
Does this breaker plug onto a busbar or bolt down?
The HJD3200 is a unit-mount (bolt-on) breaker. It requires mechanical fasteners to secure the frame to the equipment chassis or mounting pan, and it cables directly to the bus or load using the provided lug terminals.
Is this circuit breaker HACR rated?
Yes, the HJD3200 carries an HACR rating, making it suitable for use in heating, air conditioning, and refrigeration applications where group motor installations require specifically certified overcurrent protection.

Exactly what we needed, delivered complete and on time.
SuperBreakers had exactly what we needed (Breaker, Trip Unit, lug kits) - the breaker came quickly and with trip unit installed (ordered as a separate item) making integration quick and easy.
Solid phone support and communication re: tracking - overall a very good purchasing experience.
