Description
Part of the classic Series C family, this 50A three-pole breaker delivers robust protection for commercial and industrial electrical systems. It mounts seamlessly into legacy Westinghouse panelboards and motor control centers without requiring adapter kits. Finding a true 600V replacement can be difficult since modern FD frames require panel modifications. This original G-frame unit solves that issue, offering 10kAIC at 600VAC and reverse feed capabilities for versatile installation.Specifications

Product FAQs
7 answersCan I use the Eaton G3050 to replace an older Westinghouse G3050 breaker?
Yes. Eaton acquired the Westinghouse distribution and control business, and the G3050 is the direct replacement for legacy Westinghouse G3050 circuit breakers. It fits the same Series C G-frame panelboards and motor control centers without requiring adapter kits.
Is the Cutler-Hammer G3050 the same as the Westinghouse G3050?
Yes. Following Eaton's acquisition of both brands, the G3050 catalog number remains identical across Westinghouse, Cutler-Hammer, and Eaton labels. They share the exact same physical dimensions, bolt-on mounting, and electrical ratings.
Which panelboards are compatible with the G3050 breaker?
This G-frame breaker is designed for use in Eaton, Cutler-Hammer, and legacy Westinghouse Series C panelboards, switchboards, and motor control centers that accept bolt-on G-frame breakers.
What wire sizes are compatible with the G3050 load lugs?
The included load side lug terminals accept conductors from 10 AWG up to 1/0 AWG. Always verify the appropriate wire material and temperature ratings per local electrical codes before terminating.
Can I adjust the trip curve on the G3050?
No. This breaker utilizes a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection parameters are factory-calibrated for 50 amps and cannot be modified in the field.
Is the G3050 suitable for 250VDC control circuits?
Yes. While primarily used in AC panelboards up to 600VAC, the G3050 is also fully rated for 250VDC applications, providing 14 kAIC of interrupting capacity for industrial direct current systems.
Is the G3050 circuit breaker UL listed?
Yes, Eaton Series C G-frame circuit breakers, including the G3050, are listed to UL 489 standards for molded case circuit breakers, ensuring safe and reliable operation in commercial and industrial panelboards.
