Title	Potential Issue Concerning the Zpa Rating for 3 Phase Relay Type Ssc-T
Event Description	This letter is to notify you of a potential issue concerning the ZPA [Zero Point Acceleration] rating for our three phase relay type SSC-T. During a Customer Audit (week of February 4, 2013 by ABB Inc., Florence, S.C.), we discovered that our Class 1E Certification database showed the ZPA rating of our three phase SSV -T and SSC-T relays was 5.6g, while our most recent qualification (dated June 14, 2012) determined that the ZPA rating was 4.79g. A review of our Purchaser records for the last ten years indicates that one (1) affected relay was sold to WESCO: SSC-T relay completed 10/5/2007, order number 3365-960825 and serial number 11835. ABB does not have the capability to perform the evaluation to determine if a defect exists, so we are informing the purchaser of this determination so that they may evaluate the deviation or failure to comply, pursuant to 10CFR 21.21(a). ABB recommends that the affected licensee evaluate their specific application and determine whether the deviation described in this notice affects their design basis. If the licensee determines that it does, the licensee should contact ABB to determine appropriate corrective action. If you have any questions regarding this notice, please contact ABB Technical Support at 954-752-6700.
