Product FAQs
6 answersAre line and load lugs included with the RD316T35W?
No. The "W" suffix in the RD316T35W catalog number indicates that this breaker is supplied without terminals. You must purchase the appropriate lug kits separately based on your specific conductor size and material.
What enclosures are compatible with the RD316T35W breaker?
This R-frame circuit breaker is designed for bolt-on installation in Eaton Series C panelboards, switchboards, motor control centers, and approved busway applications.
Can the RD316T35W be used in reverse feed applications?
Yes, Eaton Series C R-frame circuit breakers are suitable for reverse feed use, allowing flexibility in how the breaker is wired within your distribution equipment.
How does the LSG trip unit on the RD316T35W function?
The integrated Digitrip 310 RMS electronic trip unit provides adjustable Long-Time, Short-Time, and Ground Fault (LSG) protection. This allows electricians to precisely coordinate overload, short circuit, and ground fault pickup and delay settings with the facility's overall protection scheme.
Is the Eaton RD316T35W the same as the Cutler-Hammer RD316T35W?
Yes. Eaton acquired Cutler-Hammer, and the Series C R-frame breakers are identical across both brand names. The RD316T35W can be used as a direct replacement for legacy Cutler-Hammer models with the exact same catalog number.
What is the purpose of the Ground Fault (G) protection on this breaker?
The ground fault function in the Digitrip 310 unit monitors for unintended current leakage to ground. If the leakage exceeds the adjustable pickup setting, the breaker trips to prevent equipment damage and reduce the risk of electrical fires.
