Product FAQs
8 answersWhat types of equipment are compatible with the CND3800T57W circuit breaker?
This NG-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
What does the LSIA designation mean on the OPTIM 550 trip unit?
LSIA indicates the electronic trip unit provides adjustable protection for Long-Time, Short-Time, and Instantaneous overcurrents, plus a Ground Fault Alarm function.
Does the OPTIM 550 LSIA trip unit provide ground fault tripping?
No, the LSIA configuration provides a Ground Fault Alarm to alert operators of a fault, but it does not automatically trip the breaker for ground faults. If ground fault tripping is required, an LSIG trip unit is necessary.
Does the CND3800T57W come with terminal lugs installed?
No, the "W" suffix in the catalog number indicates this breaker is supplied without terminals. You must purchase and install the appropriate Eaton N-frame lug kits separately based on your wire size requirements.
Is the CND3800T57W suitable for continuous operation at its full 800A rating?
Yes, the "C" prefix in the CND catalog number designates it as a 100% rated circuit breaker, meaning it is suitable for continuous operation at 100% of its frame rating when installed in an appropriately sized enclosure.
What rating plug is required for the CND3800T57W?
This breaker requires a Digitrip OPTIM rating plug to operate. To achieve the full 800A maximum continuous current rating, you must install the ORPN80A800 rating plug.
Can the CND3800T57W be reverse fed?
Yes, Eaton Series C N-frame circuit breakers are suitable for reverse feed applications.
Is the CND3800T57W HACR rated?
