DEFECTS AND NONCOMPLIANCE PART 21 GROUP EMAIL PART 21 - AN OPERATING MECHANISM FRONT COVER FAILED DURING LICENSEE RECEIPT INSPECTION The following information was received by facsimile:
"[ABB, Inc. provided] notification of a failure to comply with specifications associated with an operating mechanism front cover P/N 707939A00 used in low voltage electrically operated K-Line circuit breakers. A single occurrence of a newly manufactured circuit breaker failure to close was noted during Next Era Energy Seabrook Station receiving inspection supported by an ABB Medium Voltage Service Field Service Engineer. This circuit breaker was set up and tested satisfactorily during ABB cycle testing, inspection and commercial grade dedication prior to shipping. It was noted during the Seabrook receiving inspection that the control device plunger and secondary close latch were misaligned. Replacement of the operating mechanism front cover improved this alignment and the circuit breaker receipt inspection was completed satisfactorily. Inspection of the subject operating mechanism front cover indicates cause of the misalignment is due to incorrect hole locations for mounting the control device. This operating mechanism front cover was manufactured by Accutrex Products, Inc., an ABB approved vendor.
"Identification of the Subject component: ABB part numbers 707939A00 and 707939B00 operating mechanism covers. These covers are used in operating mechanisms for the K-Line electrically operated circuit breakers rated 2000 amps and below.
"Because of the large potential variety of usages of the affected circuit breakers, ABB (Medium Voltage Service) cannot determine if the potential for a substantial safety hazard exists at any licensee's facility if control device plunger and secondary close latch are misaligned. It is recommended the Licensees determine if the circuit breaker control device plunger and secondary close latch are misaligned at the next convenient maintenance opportunity defined in the ABB K-Line circuit breaker Information Bulletin."

Subject:
1 OCFR Part 21 Notification of Deviation re. K-Line Circuit Breaker Operating Mechanism Covers
- 1. This letter provides notification of a failure to comply with specifications associated with an operating mechanism front cover P/N 707939A00 used in low voltage electrically operated K-Line circuit breakers. A single occurrence of a newly manufactured circuit breaker failure to close was noted during Next Era Energy Seabrook Station receiving inspection supported by an ABB Medium Voltage Service Field Service Engineer. This circuit breaker was set up and tested satisfactory during ABB cycle testing, inspection and commercial grade dedication prior to shipping. It was noted during the Seabrook receiving inspection that the control device plunger and secondary close latch were misaligned. Replacement of the operating mechanism front cover improved this alignment and the circuit breaker receipt inspection was completed satisfactorily. Inspection of the subject operating mechanism front cover indicates cause of the misalignment is due to incorrect hole locations for mounting the control device. This operating mechanism front cover was manufactured by Accutrex Products, Inc., an ABB approved vendor. Information is provided as specified in IOCFR21 paragraph 21.21(d) (4).
- 2. Notifying individual: Jay Lavrinc, Vice President & General Manager, ABB (Medium Voltage Service), 2300 Mechanicsville Road, Florence, SC 29501
- 3. Identification of the Subject component: ABB part numbers 707939A00 and 707939B00 operating mechanism covers. These covers are used in operating mechanisms for the K-Line electrically operated circuit breakers rated 2000 amps and below.
- 4. Nature of the deviation: One of thirty breakers provided to Seabrook failed to close during receiving inspection. This issue was communicated to ABB 9/14/2012. The subject operating mechanism cover was returned to ABB for inspection and root cause analysis on 9/18/2012.
The root cause for the cover hole locations being out of position is corrective maintenance required of the six-part progressive die tooling used in the manufacturing process. Extent of condition performed by ABB indicated all P/N 707939A00 and 707939B00 in inventory had control device mounting hole locations out of position.

11-08-2012 3/4 ABB saligned plunger to secondary close latch.
Correctly aligned plunger to close latch.
- 5. Corrective actions include:
- a. Removed all P/N 707939A00 and 707939B00 covers from inventory. (Action complete)
- b. Notified Accutrex Products, Inc. of the issue and completed process audit of tooling and manufacture of P/N 707939A00 and 707939B00 covers. This review was supported by ABB Supply Chain Manager, QA Engineer and Fabrication Manager. (Action complete)
- c. ABB approved corrective maintenance repairs to five of six pieces of tooling used to manufacture P/N 707939A00 and 707939B00 covers. All maintenance and repairs to these tools are completed. One of six tools was removed from use. Secondary operations were established to drill control device mounting holes after operating mechanism covers manufactured with first piece run expected to be completed 11/15/2012.
- d. Revised P/N 707939A00 and 707939B00 Critical Characteristics to include control device mounting hole locations. (Action complete)
