Product FAQs
7 answersWhat equipment is the RD320T33W designed to be installed in?
This R-Frame breaker is engineered for use in Eaton and Cutler-Hammer Series C switchboards, motor control centers, and large industrial power distribution panels.
What does the T33W suffix indicate on this Eaton breaker?
The T33W designates that the breaker is equipped with a factory-installed Digitrip 310 RMS electronic trip unit, configured specifically with adjustable Long-Time and Short-Time (LS) protection functions.
How does the LS trip unit improve system coordination?
The Short-Time (S) function introduces an intentional delay during a fault. This allows smaller downstream breakers to trip first, isolating the fault while keeping the rest of the electrical system online.
Are the trip settings on the Digitrip 310 unit adjustable?
Yes, the electronic trip unit features adjustable dials for both long-time pickup and short-time pickup, allowing precise calibration to match your specific load and coordination requirements.
Is the RD320T33W backward compatible with older Westinghouse panels?
Yes, Eaton Series C R-Frame breakers are physically interchangeable with legacy Cutler-Hammer and Westinghouse R-Frame breakers, making them suitable for retrofits in existing switchboards.
Does this breaker require a specific mounting configuration?
Yes, it utilizes a bolt-on connection. The breaker must be bolted directly to the bus structure of the switchboard or panelboard, ensuring a secure, high-capacity connection for 2000A applications.
Can I install this R-Frame breaker in a standard lighting panel?
No, R-Frame breakers like the RD320T33W are physically large, high-capacity devices designed exclusively for heavy-duty switchboards, motor control centers, and large power distribution panels.
