Product FAQs
5 answersIs the Eaton K3175 interchangeable with the Westinghouse K3175?
Yes. Eaton acquired the Westinghouse distribution equipment division. A K3175 breaker labeled under Eaton, Cutler-Hammer, or Westinghouse shares the exact same physical dimensions, Series C K-frame footprint, and bolt-on mounting configuration.
What type of panelboards are compatible with the K3175?
This bolt-on breaker is designed for installation in Eaton Series C panelboards, legacy Westinghouse panelboards, motor control centers, and compatible switchboards that accept K-frame breakers.
How do I adjust the instantaneous trip setting on this breaker?
The K3175 features a fixed thermal and adjustable magnetic trip unit. The magnetic (instantaneous) pickup can be adjusted using the dial located on the front face of the breaker to coordinate with downstream loads and prevent nuisance tripping.
Does the K3175 provide ground fault protection?
No. This breaker is equipped with an LI (Long-Time, Instantaneous) thermal-magnetic trip unit. It provides protection against overloads and short circuits but does not include integral ground fault equipment protection.
Are the standard lugs on the K3175 rated for aluminum conductors?
Yes, the factory-installed lugs are dual-rated for both aluminum and copper wire. They accept conductor sizes ranging from 3 AWG up to 350 kcmil, making them versatile for various field wiring applications.
