Product FAQs
7 answersIs the Cutler-Hammer CAH3175 still in active production?
The CAH3175 is a legacy C-Frame circuit breaker and is considered obsolete by Eaton. It is officially superseded by the FD3175 series for new installations, though CAH3175 units are still used as direct replacements in existing enclosures.
Can I replace a CAH3175 with an FD3175?
Yes, Eaton designates the FD3175 as the modern replacement for the legacy CAH3175. You must verify that your specific panelboard or enclosure has the appropriate mounting hardware to accommodate the FD-Frame footprint.
What equipment is the CAH3175 circuit breaker designed to fit?
This C-Frame breaker is engineered for integration into legacy Cutler-Hammer and Westinghouse panelboards, switchboards, and motor control centers.
What wire sizes are accepted by the lugs on the CAH3175?
The standard line and load lugs on this breaker accept copper or aluminum conductors ranging from 6 AWG up to 350 kcmil.
How is the CAH3175 mounted within a panel?
This is a unit-mount circuit breaker, meaning it bolts directly to the chassis or mounting pan rather than plugging onto a busbar.
What type of trip unit does the CAH3175 utilize?
It features a thermal-magnetic trip unit providing fixed long-time and fixed instantaneous (LI) overcurrent protection.
Can the CAH3175 be installed in a 480V system?
No, this breaker is strictly rated for a maximum of 240V AC. Installing it in a 480V system violates its UL listing and poses a severe arc flash and fire hazard.
