The following information is provided pursuant to the requirements of
10 CFR Part 21 to report a potential safety concern. A potential safety condition may exist with the Eaton Cutler-Hammer D65 Series B1 Voltage Monitoring Relay that can cause the unit to bypass the Manual Reset feature. This could result in the D65 relay being energized without an operator manually resetting it resulting in possible personal injury or death or property damage. This condition exists with Eaton Cutler-Hammer D65 Series B1 Voltage Monitoring Relays with a manufacturing date between May 12, 2002, and February 20, 2004.
On March 25, 2004, Framatome/AREVA Electrical Products received the attached Eaton Cutler Hammer Product Safety Warning for D65 Voltage Monitoring Relays, dated March 24, 2004. The Product Safety Warning states that Eaton's Cutler-Hammer D65 Series B1 Voltage Monitoring Relays with a manufacturing date identified above may power up without being manually reset even when a NC [Normally closed] switch is wired to activate manual reset mode. This condition is only present when used in applications operating in the manual reset mode. This condition is not present when the device is used in automatic reset mode. This condition may only result when the D65 Series B1 is used and will not result if the A1 Series is used (as the A1 series did not offer the potential for manual reset).
The supply of Safety Related D65 Voltage Monitoring Relays by Framatome/AREVA Electrical Products is isolated to only one Nuclear Customer (i.e. First Energy - Davis Besse Nuclear Power Plant). The First Energy Davis Besse Nuclear Power Plant was notified by Framatome/AREVA Electrical Products on April 2, 2004.
