Further, a method for enabling an electronic trip unit (ETU) to trip a circuit breaker using power from an external device is provided.

Abstract: A circuit protection device for monitoring a current flowing from an electrical distribution line through a trip mechanism to a load includes an input conductor configured to receive a current signal from a sensor. At least one resistor is arranged to receive the current signal from the input conductor, and provides a voltage signal proportional to the current signal. The circuit protection device includes a control circuit coupled in parallel with the resistor and a power supply that receives the current signal from the resistor and supplies power to the control circuit based on the current signal. The control circuit is configured to receive the voltage signal and determine an amplitude of the current flowing through the trip mechanism based on the voltage signal. The control circuit is also configured to determine whether a predetermined current threshold is exceeded and to generate a control signal to activate the trip mechanism.

Abstract: A trip unit for a circuit breaker having at least one sensor for monitoring a current in a protected circuit and a tripping system is provided. The trip unit includes a first controller operably coupled to receive a current signal from the at least one sensor and electrically coupled to the tripping system. The first controller includes a first processor that transmits a first signal to the tripping system in response to a detection of a first undesired condition. A second controller is operably coupled to receive the current signal from the at least one sensor and is electrically coupled to the tripping system in parallel with the first controller. The second controller includes a second processor that detects the first condition and transmits a second signal to the tripping system after a predetermined first time period.

Abstract: A beverage holder for use in vehicles that prevents beverages placed within the holder from spilling. The beverage holder includes a tray and drink well housed within the tray. Additionally, the tray may have a pivot member mounted to it which connects the tray to a beverage guard. The beverage guard may be moved in a range of positions so that it completely covers the drink well and also leaves the drink well free for a cup to be placed within. The beverage guard is slightly larger than the size of the drink well and can be rotated to cover the drink well when a cup or glass has been placed within it. When not in use, the beverage guard may be moved in a position not covering the drink well.
