General Electric Thermal Overload Relay, model CR124G011, part number DD317A7861P003 Under normal operation, the relay would latch into the tripped state requiring a manual reset of the relay. If the relay with the deviation were installed, and if the relay were required to trip, it would do so; however, it would also automatically reset. The unexpected reset could result in unintended cycling of associated equipment including repeated exposure to inrush current and potential damage.
Bench testing would be expected to identify this condition prior to installation. Based on a review, this potential condition does not affect installed equipment. The affected relay was stored at JAF since July 1998.
