Eaton / Cutler-Hammer RGH325035E Molded Case Circuit Breaker

This RG frame circuit breaker is engineered specifically for installation in Eaton Pow-R-Line switchboards and motor control centers. It typically serves as a high-capacity main or feed-thru device within these systems.

The Digitrip 310 electronic trip unit features Long-Time, Short-Time, and Ground Fault parameters. This allows panel builders to precisely dial in overload pickup, short-circuit coordination delays, and ground leakage limits for comprehensive equipment protection.

This is a unit-mount configuration, meaning it is bolted directly to the backpan or busbar framework of the switchboard. It does not utilize a draw-out carriage or plug-in mounting base.

Yes. Eaton acquired Cutler-Hammer and continues to manufacture the Series G line. The RGH325035E is functionally identical and fully compatible with existing Cutler-Hammer RG frame installations.

No. The ground fault function on the Digitrip 310 is designed exclusively for equipment protection to mitigate arcing damage. It does not provide the highly sensitive Class A personnel protection found in residential GFCI devices.

No. The breaker comes complete with an adjustable rating plug connected to the Digitrip 310 unit. Electricians can modify the specific time and current parameters directly on the existing interface to coordinate with changing downstream loads.

While the underlying RG frame utilizes standard stud and tapped pad connections, this specific configuration includes line and load side lug terminals to allow for direct copper or aluminum cable termination.

The short-time function allows the breaker to purposefully delay tripping for a fraction of a second during a fault. This gives smaller downstream breakers the opportunity to clear the fault first, isolating the hazard locally without unnecessarily shutting down the entire main switchboard.
