A format is presented that provides a concise and meaningful method for recording pertinent information on power circuit breaker field failures. It is recommended that this format be utilized in record keeping and directing corrective action to improve field reliability of power circuit breakers.

A Failure Reporting Form, figures 1 and 2, has been developed by the IEEE Switchgear Committee to improve the reliability of circuit breakers through uniform reporting of field failures. The use of this approach is the recommended practice for all users of power circuit breakers.

The use of the Failure Reporting Form, included in this document, is recommended to standardize reporting of field failures and to use these experiences to improve the reliability of power circuit breakers.
