摘要： Improvements to a rating plug for an electronic trip unit of a circuit breaker are disclosed. The rating plug includes a non-volatile memory which has access to current and frame rating information. A microcomputer in the electronic trip unit may receive new current rating information over the World Wide Web from a vendor system to update the current rating information of the rating plug. A program within the circuit breaker may detect errors in the new current rating information and may reject such and revert to a safe mode of operation. A billing system may be connected to the vendor system for calculating charges based on the transmission of the new current rating information. Preferably, the non-volatile memory of the rating plug is programmed at the factory site and a label adhered to the outer case of the rating plug for indicating the current rating. The rating plug may then be inserted within the electronic circuit breaker at the field and the current rating altered as necessary using the remote altering system.

摘要： A door operator operates a door that is rotatable about an axis of rotation between an open position and a closed position. The door operator comprises an output shaft, a closing assembly, and a motor. The output shaft is rotatable between a first position and a second position, and is coupled to the door such that rotation of the output shaft pivots the door about the axis of rotation and rotation of the door about the axis of rotation rotates the output shaft. The closing assembly is coupled to the output shaft to apply a torque to the output shaft, wherein the torque applied by the closing assembly rotates the output shaft such that the rotation of the output shaft by the closing assembly rotates the door toward the closed position. The motor is coupled to the output shaft via a clutch to selectively apply opening and/or closing torque to the output shaft.
