B-LINE CNDC3800T56W – Frequently Asked Questions
1) Does the Eaton CNDC3800T56W breaker come with lugs or terminals?
No. The CNDC3800T56W ships without terminals, so you have to order the NG-frame lug or terminal kit separately to land your conductors. Plan on that before the install date, because an 800A breaker with no lugs cannot be terminated.
2) Is 600 volt three-phase within range for this Series C breaker?
Yes. The CNDC3800T56W is rated 600 Vac and is a three-pole device, so it suits 600 V, 480 V or 208 V three-phase service and feeder applications. Do not apply it above 600 Vac.
3) What does the OPTIM 550 electronic LSIG trip unit actually give me over a thermal-magnetic breaker?
LSIG means four adjustable protection elements: long time, short time, instantaneous and ground fault. On a thermal-magnetic breaker you get long time and instantaneous only, fixed or coarsely adjustable. The electronic OPTIM 550 unit on this NG-frame breaker lets you set pickups and delays to coordinate selectively with downstream devices and to provide the ground fault protection required on larger services. If you do not need coordination or ground fault sensing, a thermal-magnetic NG breaker is the simpler choice.
4) Is this a complete breaker or just a frame I have to build up?
Complete breaker. The CNDC3800T56W arrives as a finished NG-frame device with the OPTIM 550 electronic trip unit installed at 800A, so no separate rating plug or trip unit assembly is needed. Terminals are the one thing not included.
5) How much space and how much weight do I need to plan for mounting this NG-frame breaker?
Published dimensions are 8.25 inches high by 8.25 inches wide with a 1 inch length/depth figure, and the unit weighs 45 lb. At that weight it is a two-person lift into a switchboard or panel, and the mounting provisions have to be rated for it.
6) Will this 800A breaker provide the ground fault protection my service needs?
The trip unit is electronic LSIG, and the G element is integral ground fault protection, so ground fault sensing is built into the breaker rather than added as a separate relay. Settings are adjustable at the OPTIM 550 trip unit. For the specific listings and standards that apply to your installation, confirm compliance details with Eaton.
