Product FAQs
6 answersWhat equipment is the Eaton HJD3175W circuit breaker compatible with?
This J-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
What does the "W" suffix mean in the HJD3175W catalog number?
In Eaton Series C nomenclature, the "W" suffix indicates the breaker is factory-configured without line or load terminals. You will need to source and install the appropriate lugs separately based on your wire size and material.
What type of trip unit is installed in the HJD3175W?
It features an interchangeable thermal-magnetic trip unit with fixed thermal and adjustable magnetic settings. This provides standard Long-Time and Instantaneous (LI) protection for your circuit.
Can the HJD3175W be used in DC power systems?
Yes, this breaker is rated for use in DC systems up to 250 VDC, where it provides an interrupting capacity of 22 kAIC.
How is the Eaton HJD3175W breaker mounted?
It is a unit-mount breaker, meaning it bolts directly to the chassis or mounting pan of the enclosure rather than plugging onto a busbar.
Can I use the HJD3175W to replace standard JD or JDB breakers?
Yes, the HJD3175W shares the same physical dimensions and mounting footprint as other Series C J-frame breakers. The "H" designates it as the high-interrupting version, making it a suitable drop-in replacement or upgrade for standard JD breakers.
