Product FAQs

7 answers
Can the Eaton GHC2045 be mounted on a standard 35mm DIN rail?

Yes, this breaker can be mounted to a standard 35mm DIN rail, but it requires a separate adapter. For two-pole G-frame breakers like the GHC2045, use Eaton DIN rail adapter part number 1225C79G01.

Is the GHC2045 rated for use in direct current (DC) circuits?

Yes, in addition to its AC ratings, this breaker is rated for 125/250VDC applications with an interrupting capacity of 14kAIC.

What type of enclosures or panels are compatible with the GHC2045?

This unit-mount, bolt-on breaker is designed for use in Eaton Series C enclosures, OEM control panels, and switchgear that accept G-frame molded case circuit breakers.

Can the trip settings on the GHC2045 be adjusted in the field?

No, this breaker features a fixed thermal and fixed magnetic trip unit providing long-time and instantaneous (LI) protection. The trip settings are factory set and cannot be adjusted.

What wire sizes are accepted by the terminals on the GHC2045?

The factory-installed lugs on this breaker accept wire gauges ranging from 14 AWG up to 1/0 AWG.

What frame size is the Cutler-Hammer GHC2045?

It belongs to the Eaton Series C family and uses a standard G-frame footprint, making it a direct replacement for older Cutler-Hammer G-frame breakers with the same specifications.

Are Eaton and Cutler-Hammer GHC2045 breakers the same?

Yes, Eaton acquired Cutler-Hammer and continues to manufacture the Series C G-frame breakers under the Eaton brand. A GHC2045 labeled as Cutler-Hammer is functionally identical to one labeled as Eaton.
