Product FAQs
6 answersCan the Eaton GHC2040 be mounted on a DIN rail?
Yes, the GHC2040 can be mounted on a standard 35mm DIN rail, but it requires a separate adapter. For 1-pole and 2-pole G-Frame breakers, use Eaton DIN rail adapter kit part number 1225C79G01.
Is the GHC2040 suitable for direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 125/250VDC, providing an interrupting capacity of 14kAIC.
Is the Cutler-Hammer GHC2040 HACR rated and suitable for reverse feeding?
Yes, the GHC2040 is HACR rated for use with heating, air conditioning, and refrigeration equipment. It also supports reverse feed configurations for specialized panelboard setups.
What wire size range do the terminals on the GHC2040 accept?
The GHC2040 comes standard with line and load lugs that accommodate wire gauges from 14 AWG up to 1/0 AWG.
What types of panels or enclosures are compatible with the GHC2040?
This unit-mount G-Frame breaker is designed for use in Eaton Series C enclosures, motor control centers, and OEM panels that accept feed-thru molded case circuit breakers.
Is an Eaton GHC2040 the exact same breaker as an older Cutler-Hammer GHC2040?
Yes. Eaton acquired Cutler-Hammer, and they continue to manufacture the Series C G-Frame breakers under the Eaton name. An Eaton GHC2040 is a direct, drop-in replacement for a legacy Cutler-Hammer GHC2040.
