Dear W. DeYoung:
)
The contractor Equipment Business Operations of the General Electric
-s Company has determined that a reportable defect exists on certain of its AK-25, AKR-30 and. AKR-50 Low-Voltage Power Circuit Breakers. The following is a text of our notification for your use as necessary:
It has come to our attention that AK-25, AKR-30, and AKR-50 i
Low-Voltage Power Circuit Breakers equipped with electro-mechanical trip units may contain.assen611es improperly l
manufactured such that the circuit breaker fails to trip as intended. These circuit breakers are used in direct current applications.
The General Electric Company proposes to correct this potential problem in all Nuclear Class IE applications. The l
correction will consist of returning the devices in question to j
l the factory for inspection, repair and re-assen61y as necessary, and re-testing to ensure proper operation. General Electric personnel are presently reviewing their files to determine which Nuclear facilities have these breakers and will soon be contacting the affected Nuclear sites to arrange for the corrections at a mutually convenient time.
The potentially affected circuit breakers were manufactured
)
from mid-1976 until March,1983. Only the AK-25 AKR-30, and l
AKA-50 Circuit Breakers equipped with electro-mechanical trip units are involved.
l If you require any further information, please contact me.
