Product FAQs
7 answersWhat enclosures and equipment are compatible with the RD320T35W?
This Series C R-Frame breaker is designed for use in Eaton panelboards, switchboards, and motor control centers. It requires an appropriately sized enclosure to ensure proper heat dissipation for 2000A operation.
Can I use this breaker in reverse-feed applications?
Yes, Eaton Series C R-Frame electronic trip breakers like the RD320T35W are suitable for reverse-feed applications.
What wire sizes are accepted by the TA2000RD lug kit for this breaker?
When equipped with the standard TA2000RD lug kit, the terminals accept up to six #2 AWG to 600 kcmil copper or aluminum conductors per phase.
What specific trip unit is included with the RD320T35W?
This breaker includes a microprocessor-based Digitrip 310 RMS electronic trip unit. The T35W suffix indicates it is configured with adjustable Long-Time, Short-Time, and Ground-Fault (LSG) protection.
Can the 2000A continuous current rating be adjusted?
Yes. The electronic trip unit allows for adjustability. By swapping the interchangeable rating plug or adjusting the long-time pickup settings on the Digitrip unit, the breaker can be configured to protect lower-amperage circuits.
Does the RD320T35W provide ground fault protection?
Yes, the G in its LSG trip unit designates built-in, adjustable ground-fault protection. This is critical for equipment safety and coordination in high-amperage industrial systems.
Can the RD320T35W replace legacy Cutler-Hammer or Westinghouse breakers?
Yes, Eaton Series C R-Frame breakers are backward compatible. They can directly replace legacy Cutler-Hammer and Westinghouse R-Frame breakers with matching frame sizes and specifications.
