Product FAQs
6 answersWhat types of enclosures or panels is the GHC3030 compatible with?
This breaker is designed for use in Eaton Series C enclosures and various OEM panels. It can also be mounted on a standard DIN rail if the appropriate adapter is used.
Can the GHC3030 be mounted on a DIN rail?
Yes, although it is a unit mount breaker, it can be installed on a DIN rail by using a compatible Eaton DIN rail adapter.
Is the Eaton GHC3030 the same as the Cutler-Hammer GHC3030?
Yes. Eaton acquired Cutler-Hammer, and they share the same catalog numbers and physical designs. A breaker labeled Cutler-Hammer GHC3030 is an exact match for the Eaton GHC3030.
Can this Series C breaker be used in direct current (DC) applications?
Yes, the GHC3030 is rated for use in DC circuits up to 125/250VDC, providing a 14kA interrupting capacity for these applications.
How does the fixed thermal magnetic trip unit operate on this breaker?
The trip unit features Long-Time (L) and Instantaneous (I) functions. The thermal component provides delayed tripping for sustained overloads, while the magnetic component trips instantly to protect against short circuits. Both settings are fixed and cannot be adjusted in the field.
What wire sizes do the standard lugs on this breaker accept?
The included lugs are designed to accommodate wire gauges ranging from 10 AWG up to 1/0 AWG.
