Product FAQs

8 answers
Which Eaton enclosures are compatible with the RGH325032E breaker?

This RG-frame breaker is designed for use in Eaton Pow-R-Line panelboards, switchboards, and motor control centers that accommodate Series G unit mount breakers.

Does the RGH325032E come with standard wire lugs?

No. This breaker features stud or tapped pad terminals for bolt-on connections. If you are not connecting directly to a busbar, you will need to purchase and install compatible mechanical or compression lugs separately based on your wire size.

How does the LSI electronic trip unit benefit system coordination?

The Long-Time, Short-Time, and Instantaneous (LSI) settings allow panel builders to fine-tune the trip curve. This ensures that a fault clears at the breaker closest to the issue without unnecessarily tripping the main 2500A breaker, improving overall system reliability.

Is the RGH325032E part of the Series C or Series G family?

The RGH325032E is an RG-frame breaker, which belongs to the Eaton Cutler-Hammer Series G family of molded case circuit breakers.

Can this breaker be DIN rail mounted?

No. The RGH325032E is a large 2500A unit mount breaker that requires a heavy-duty bolt-on connection directly to the panelboard or switchboard bus structure.

Why is an electronic trip unit preferred for a 2500A breaker?

Electronic trip units provide higher accuracy and repeatability compared to traditional thermal-magnetic units. They are essential in high-amperage applications to meet strict safety codes for selective coordination and arc flash mitigation.

Is this breaker suitable for DC voltage applications?

The provided specifications list this breaker for AC voltage only, up to 600VAC. Electronic trip units in the Series G family rely on current transformers that are not rated for DC applications.

What does the "32" signify in the RGH325032E catalog number?

In the Eaton Series G nomenclature, the "32" indicates the breaker is equipped with a Digitrip electronic trip unit featuring LSI (Long-Time, Short-Time, Instantaneous) protection functions.
