Product FAQs
6 answersIs the Eaton GHC2070 the same as the Cutler-Hammer GHC2070?
Yes. Eaton acquired Cutler-Hammer, and they manufacture this breaker under the same GHC2070 catalog number. They are physically and functionally identical.
Can the GHC2070 be mounted on a DIN rail?
Yes, this unit-mount breaker can be installed on a standard 35mm DIN rail, but it requires a separate adapter bracket (Eaton part number 1225C79G01 for 1-pole and 2-pole G-frame breakers).
What wire sizes are compatible with the GHC2070, and how should the lugs be torqued?
The standard lugs accept 10 to 1/0 AWG copper or aluminum wire. Because required torque values vary depending on the exact wire gauge used, you must refer to the torque chart printed directly on the side of the breaker to ensure a safe and compliant connection.
What does the "LI" trip function mean on this breaker?
"LI" stands for Long-Time and Instantaneous. The Long-Time function uses a fixed thermal element to protect against overloads, while the Instantaneous function uses a fixed magnetic element to trip immediately during a short circuit.
Can the GHC2070 be used in DC circuits?
Yes, this breaker is rated for DC applications up to 125/250VDC with an interrupting capacity of 14kAIC. When applying it at 250VDC, follow Eaton's wiring guidelines for multi-pole DC configurations.
What type of enclosures are compatible with the GHC2070?
This breaker is designed for use in Eaton Series C enclosures, OEM control panels, and motor control centers that accept G-frame unit-mount breakers.
