B-LINE CRD320T51W – Frequently Asked Questions
1) Does the Eaton Series C CRD320T51W circuit breaker come with lugs or terminals?
No. The CRD320T51W ships without terminals, so you need to order the lug or terminal kit separately for your conductor size and termination method. On a 2000A three-pole frame that usually means multiple conductors per phase or a bus connection, so settle the termination before the gear ships.
2) What is the interrupting rating of the CRD320T51W at 480V?
65 kAIC at 480 Vac. It is also rated 125 kAIC at 240 Vac and 50 kAIC at 600 Vac, with a 600 Vac maximum voltage rating. Match the available fault current at your service point against the voltage you are actually running, not just the highest number on the label.
3) Does this Eaton CRD breaker have ground fault protection?
No. The CRD320T51W uses an electronic LI trip unit, meaning long time and instantaneous functions only. There is no short time or ground fault element in that trip designation, so if your drawing calls for LSIG or LSI you need a different trip unit.
4) Will the CRD320T51W work on a 600V three-phase service?
Yes. The breaker is rated to 600 Vac and is three-pole, so it suits 600V three-phase distribution. At that voltage the interrupting capacity is 50 kAIC, which is the number your coordination study has to work against.
5) How much space and support does a 2000A Series C CRD breaker need?
Plan for a unit measuring 20 inches by 15.5 inches by 15.5 inches and weighing 130 pounds. That weight means rigging or two people for the install, and it is a complete breaker rather than a trip unit or frame assembly, so it goes in as one piece.
6) Is the CRD320T51W a complete breaker or just a replacement trip unit?
It is supplied as a complete breaker, a three-pole CRD frame with the electronic trip already fitted. You are not ordering a trip unit to drop into an existing frame. Terminals are the one thing not included.
