Description
The GC3015 is a legacy 15-amp, 3-pole molded case circuit breaker from Eaton's Series C family. Designed for commercial applications, it provides reliable thermal-magnetic protection for branch circuits. As an exact physical match for older installations, this unit mount breaker installs into Westinghouse Series C panelboards without adapters. Officially replaced by the GD3015, this G-Frame MCCB delivers a 65 kAIC rating at 240VAC and features fixed long-time and instantaneous trip functions.Specifications

Product FAQs
6 answersWhat equipment is the GC3015 circuit breaker designed to fit?
This G-Frame breaker is engineered for installation in Eaton and Westinghouse Series C panelboards, as well as various motor control centers and standalone enclosures requiring a unit mount configuration.
How is the GC3015 mounted within an electrical system?
It utilizes a unit mount, feed-thru design. Instead of snapping or bolting directly to a panelboard bus, it is secured independently and wired via cable-in and cable-out connections using the provided lugs.
Can I use the Eaton GC3015 to replace an older Westinghouse GC3015?
Yes. Eaton acquired the Westinghouse molded case circuit breaker product line. The current Eaton GC3015 shares the exact same physical dimensions and electrical characteristics as the legacy Westinghouse model, ensuring a direct replacement.
Is there a newer direct replacement for the GC3015?
Yes, Eaton has officially designated the GD3015 as the modern replacement for the legacy GC3015. Both are G-Frame breakers, but the GC3015 is often preferred when maintaining existing Series C installations without upgrading the entire setup.
What wire sizes are compatible with the GC3015 terminals?
The factory lugs on this breaker accommodate a wide range of conductors, accepting wire gauges from 14 AWG up to 1/0 AWG for both the line and load side connections.
How does the trip mechanism function on the GC3015?
It utilizes a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) protection. The thermal element responds to sustained overloads, while the magnetic element trips immediately during high-current short circuits.
