Description
Part of the trusted Series C line, this 30-amp, 3-pole unit mount breaker delivers robust overcurrent protection for industrial environments. Built to the exact dimensions of the original G-Frame hardware, it ensures seamless compatibility with vintage Westinghouse and Cutler-Hammer panelboards. Facilities maintaining older gear can use this as a direct substitute before transitioning to the newer GD3030. Delivering 65 kAIC at 240VAC, it handles demanding fault conditions with fixed LI settings.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the GC3030 circuit breaker?
This G-Frame breaker is designed for use in Eaton and Westinghouse Series C panelboards, as well as compatible motor control centers.
Is the Westinghouse GC3030 the same as the Eaton GC3030?
Yes. Eaton acquired the Westinghouse distribution equipment division. Breakers labeled under the Eaton, Cutler-Hammer, or Westinghouse brands with the GC3030 catalog number are physically and electrically identical.
Can I use the GD3030 instead of the GC3030?
Yes, the GD3030 is the modern Eaton replacement for the legacy GC3030. Both are 30A, 3-pole G-Frame breakers, but the GC3030 is often sourced to maintain exact physical and visual matching in older Westinghouse panelboards.
Is the GC3030 suitable for reverse feed applications?
Yes, this thermal magnetic molded case circuit breaker is suitable for reverse feed use, allowing it to be back-fed in compatible panelboards.
Is the GC3030 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment branch circuits.
Do I need to purchase separate lugs for the GC3030?
No, the GC3030 comes standard with factory-installed lugs that accept 14 AWG to 1/0 AWG wire for feed-thru connections.
Can I adjust the trip curve on the GC3030?
No, this breaker features non-interchangeable trip units. Both the thermal (long-time) and magnetic (instantaneous) trip functions are fixed and cannot be adjusted in the field.
