Product FAQs
7 answersWhat does the 33 signify in the RGH325033E catalog number?
It indicates the breaker is equipped with a Digitrip 310 electronic trip unit configured with Long-Time and Short-Time (LS) trip functions.
Is the RGH325033E suitable for reverse feed applications?
Yes, all Eaton Series G R-Frame circuit breakers are designed to be suitable for reverse feed use.
Does the Digitrip 310 trip unit require external control power to operate?
No, the Digitrip RMS 310 is completely self-contained. It derives all required sensing and tripping power directly from the current sensors within the circuit breaker while it is carrying current.
What is the difference between the RGH and RGC frames?
Both are Eaton Series G R-Frame breakers, but they have different interrupting capacities. The RGH is rated for 65 kAIC at 480VAC, while the RGC is a higher-tier frame rated for 100 kAIC at 480VAC.
How can the electronic trip unit on the RGH325033E be field tested?
The Digitrip 310 includes built-in test points on the front panel. It can be functionally tested in the field using a compatible Eaton test kit, such as the STK2, to verify the trip unit operation.
How is the continuous current rating established on this breaker?
The continuous current is determined by an interchangeable rating plug installed in the Digitrip 310 trip unit. For the RGH325033E, a 2500A rating plug (such as the A25RES25T1 or RES2500LSG) is used to set the maximum continuous current.
Can this breaker be used in older Cutler-Hammer switchboards?
Yes, the Series G R-Frame shares the same physical footprint as the older Series C R-Frame (such as RD and RDC breakers), making it compatible with many legacy Cutler-Hammer Pow-R-Line switchboards and motor control centers.
