Product FAQs
7 answersWhat types of enclosures and panels are compatible with the GHC3020?
This Series C G-frame breaker is designed for unit mounting in Eaton Series C enclosures and various OEM panels. It can also be installed on a standard DIN rail when using the appropriate mounting adapter.
Can the GHC3020 be mounted on a DIN rail?
Yes, while it is natively a surface-mounted unit mount breaker, it can be installed on a DIN rail by utilizing a compatible Eaton DIN rail adapter bracket.
What does the 480Y/277VAC voltage rating indicate for installation?
The slash voltage rating means this breaker is intended for use on solidly grounded wye electrical systems where the line-to-ground voltage does not exceed 277V. It is not suitable for 480V ungrounded delta systems.
Can this breaker be used in DC voltage applications?
Yes, the GHC3020 is rated for DC applications up to 125/250VDC, providing an interrupting capacity of 14kAIC at that voltage.
What wire sizes do the standard terminals on this breaker accept?
The factory-installed screw and clamp terminals accommodate wire gauges ranging from 14 AWG up to 1/0 AWG.
Is there a difference between the Cutler-Hammer GHC3020 and the Eaton GHC3020?
No, they are the exact same product. Eaton acquired Cutler-Hammer and continues to manufacture the Series C G-frame breakers under the Eaton brand name.
Are the trip settings on the GHC3020 field adjustable?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. It does not allow for field adjustments of the long-time or instantaneous trip curves.
