  • CONTROL AND MONITORING UNIT FOR A CIRCUIT INTERRUPTER ELECTRONIC TRIP UNIT AND SYSTEM INCLUDING SAME
    Publication number: 20140118875
    Abstract: A circuit interrupter system includes a circuit interrupter including a processing unit, a serial port interface operatively coupled to the processing unit for enabling communication with the processing unit, and a USB processing unit configured to run a USB stack and operatively coupled to the serial port interface for enabling communication with the processing unit through the serial port interface, and a portable computing device selectively connectable to the USB processing unit of the circuit interrupter through a USB connection, the portable computing device being structured to function as a USB host and to implement a graphical user interface for enabling communication between the portable computing device and the processing unit of the circuit interrupter through the serial port interface and the USB processing unit when the portable computing device is connected to the USB processing unit of the circuit interrupter.

  • Trip unit providing remote electrical signal to remotely indicate that an arc reduction maintenance mode is remotely enabled, and electrical switching apparatus including the same
    Patent number: 8508891
    Abstract: An electrical switching apparatus includes separable contacts; an operating mechanism structured to open and close the separable contacts; and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes an input structured to receive a remote signal to remotely enable an arc reduction maintenance mode, a first circuit structured to enable the arc reduction maintenance mode in response to the received remote signal, and a second circuit structured to provide an electrical signal remote from the trip mechanism in order to remotely indicate that the arc reduction maintenance mode is remotely enabled.
