Product FAQs
8 answersWhat is the difference between the Eaton JD3225 and the JDB3225?
The JDB3225 is identical to the standard JD3225, but the B suffix designates it is suitable for reverse-feed applications. It features no line and load labeling, and the thermal-magnetic trip unit is factory-sealed to the breaker frame.
What equipment is compatible with the JDB3225?
This Series C J-Frame breaker mounts directly into standard Eaton panelboards, switchboards, motor control centers, and industrial enclosures.
What lug kit is standard for the JDB3225, and what wire sizes does it accept?
The standard line and load lug kit is the TA250KB. It accepts aluminum or copper wire ranging from 4 AWG to 350 kcmil.
Can the trip unit on the JDB3225 be swapped or upgraded in the field?
No. Because the JDB3225 is rated for reverse-feed applications, the thermal-magnetic trip unit is factory-sealed to the frame and is non-interchangeable.
Can the JDB3225 be used to replace older Westinghouse or Cutler-Hammer breakers?
Yes, the JDB3225 is a direct drop-in replacement for legacy Cutler-Hammer and Westinghouse JD3225 and HJD3225 circuit breakers.
What does the LI trip function code indicate on this breaker?
The LI code means the breaker provides Long-Time (thermal) and Instantaneous (magnetic) trip functions for standard overload and short-circuit protection. Both settings are fixed on this specific model.
Is the JDB3225 rated for DC voltage applications?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with an interrupting capacity of 10kA, making it suitable for specific DC control circuits or battery systems.
Why are there no line and load markings on the JDB3225?
The absence of line and load markings indicates the breaker is approved for reverse-feed installations, allowing power to be supplied to either the top or bottom terminals safely without violating code.
