Eaton / Cutler-Hammer RD325T35W Molded Case Circuit Breaker

No. This breaker is specifically designed for Eaton Series C panelboards, switchboards, and motor control centers that are configured to accept R-Frame breakers. Due to its 2500A capacity and large physical footprint, it requires a dedicated R-Frame mounting space and cannot be installed in standard smaller-frame panels.

The T35W suffix indicates a Digitrip 310 RMS electronic trip unit with LSG functions. This provides adjustable settings for long-time pickup and delay, short-time pickup and delay, and ground-fault pickup and delay. These adjustments allow electricians to precisely coordinate the breaker with other devices in the power distribution system.

This breaker features a bolt-on connection and requires heavy-duty R-Frame lug kits to safely terminate 2500A conductors. Electricians typically use multi-wire lug kits, such as the Eaton B2500RD, which must be selected based on the specific wire size and material used in the installation.

No. Eaton acquired Cutler-Hammer and continued manufacturing the Series C line under the Eaton name. An Eaton RD325T35W is physically and electrically identical to a Cutler-Hammer RD325T35W, making it a direct drop-in replacement for older installations.

Yes. When installing the RD325T35W at its standard 80 percent continuous rating inside an enclosure, Eaton requires the use of coated or painted buswork to manage heat dissipation. Installers must also ensure the enclosure meets Eaton minimum dimensional requirements to maintain safe operating temperatures.
