Description
Maintaining older electrical infrastructure requires reliable components like this 175A J-frame molded case breaker. It installs into vintage Eaton, Cutler-Hammer, and Westinghouse enclosures or panelboards requiring unit-mount configurations. While this specific model features a 22kAIC rating at 480VAC, facilities upgrading their systems can substitute it with the JDB3175 for a direct fit or the JGS3175 using an adapter kit.Specifications

Product FAQs
7 answersWhat enclosures and panelboards accept the JS360175A circuit breaker?
This Series C breaker is compatible with Eaton, Cutler-Hammer, and legacy Westinghouse J-Frame enclosures and panelboards.
Does the JS360175A feature an adjustable trip setting?
Yes, it utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
What wire sizes and materials are supported by the JS360175A terminals?
The factory-installed line and load lugs accept 4 AWG to 350 kcmil wire and are rated for both aluminum and copper conductors.
How is the JS360175A secured within a panel?
It is a unit-mount, feed-thru breaker. It bolts directly to the enclosure backpan or mounting plate rather than plugging into a busbar.
Is the JS360175A suitable for direct current systems?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC applications with a 10kA interrupting capacity.
Are Eaton and Cutler-Hammer JS360175A breakers interchangeable?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse electrical distribution lines. A JS360175A breaker will fit and function identically regardless of which of these three brand names is printed on the label.
What precautions should be taken before installing the JS360175A?
Always verify that the panel is fully de-energized before installation. Ensure that the line and load lugs are torqued to the exact specifications listed on the breaker faceplate to prevent terminal overheating.
