ABB identified a deviation with close latc … ABB identified a deviation with close latch springs provided since 1/20/2010 used in medium voltage HK circuit breakers. These close latch springs are used on new legacy HK circuit breakers, replaced during HK circuit breaker refurbishment activities, and provided in HK refurbishment kits and as component items. The ABB part number for the close latch spring is: 162374A00. The nature of the deviation is a reduced spring force. There is a potential for an aged HK circuit breaker with hardening grease and this reduced spring force not to close.</br>The following is a list of affected customers:</br>Detroit Edison Fermi 2</br>Dominion VA</br>DTE</br>Duke Catawba</br>Duke Energy - Seneca</br>Duke Energy - Cataw</br>Duke Huntersville</br>Duke McGuire</br>Duke Oconee</br>Entergy River Bend</br>Exelon Limerick</br>Exelon Nuclear</br>Exelon Peach Bottom</br>Exelon Point Beach</br>First Energy Beaver Valley</br>Georgia Power Plant Vogtle</br>Nextera Point Beach</br>Nextera Seabrook</br>Prairie Island Nuclear</br>Progress Energy Brunswick</br>Progress Energy Crystal River</br>PSEG Alloway Creek</br>Southern Cal Edison</br>STP Nuclear</br>TVA Sequoyah.</br>* * * UPDATE AT 1715 EDT ON 04/08/15 FROM DAVID C.

The initial time period of concern reported was January 2010 to July 2013.
