Product FAQs
7 answersDoes the CNDC3800T33W come with terminal lugs installed?
No. The 'W' suffix in the catalog number indicates this breaker is supplied without terminals. You will need to purchase the appropriate line and load lugs separately based on your specific wire size and conductor material.
Is the Eaton CNDC3800T33W a 100 percent rated circuit breaker?
Yes. The 'C' prefix in the CNDC catalog number designates that this N-Frame breaker is 100 percent rated. It can carry its full 800A continuous current rating when installed in an enclosure that is listed for 100 percent rated applications.
What type of trip unit is installed in the CNDC3800T33W?
This breaker features a Digitrip 310 RMS electronic trip unit. The 'T33' in the part number indicates it includes adjustable Long-Time and Short-Time (LS) trip functions, allowing for precise coordination in your electrical distribution system.
Can the CNDC3800T33W be used to replace older ND or HND breakers?
Yes. The CNDC3800T33W shares the same physical dimensions and bolt patterns as other Eaton Series C N-Frame breakers, including ND, HND, and NDC models. However, you must verify that its 100 percent continuous current rating and interrupting capacity meet your specific system requirements.
Is there a difference between the Cutler-Hammer and Eaton versions of the CNDC3800T33W?
No. Eaton acquired Cutler-Hammer and continues to manufacture the Series C product line under the Eaton brand. A CNDC3800T33W breaker labeled Cutler-Hammer is functionally identical to one labeled Eaton.
Can the CNDC3800T33W be reverse fed?
Yes. Standard Eaton Series C electronic trip breakers without ground fault protection, such as this LS-trip model, are suitable for reverse feed applications. Always verify specific panelboard labeling before reverse feeding.
Does the CNDC3800T33W provide True RMS sensing?
Yes. The integrated Digitrip 310 electronic trip unit utilizes True RMS sensing to accurately measure current, ensuring reliable protection even in systems with high harmonic distortion.
