    Abstract: The rotational optical switch of the present invention includes a switch enclosure, a light conductor, an optical shutter, a torsion spring biasing the shutter towards a bistable state, and a shutter actuator. The switch enclosure generally encloses the remaining components. The light conductor is received in the switch enclosure and extends between the enclosure and a transceiver, which provides a signal reflective of the state of the optical shutter. The optical shutter is pivotally mounted within the switch enclosure and is bistable between a reflective state which reflects light into the light conductor, and a nonreflective state which does not reflect light into the light conductor. The shutter pivots on arms to either end of a support cylinder which have knife edges. The shutter actuator is pivotally connected to the optical shutter by the torsion spring to cause the optical shutter to snap between the bistable states. The optical shutter has two reflectors in opposite reflective states. A second conductor is always in the opposite reflector condition.

    Abstract: A circuit breaker system uses a microprocessor for calculating at least one function of a measured current flow. The microprocessor provides other functions such as serial data stream communications, the ability of many circuit breaker systems to communicate with a central computer, storage of trip information concerning the last trip, storage of historical trip information concerning a number of past tips, EEPROM memory for storing trip information, the microprocessor may inhibit tripping on a high current fault to permit storage of trip information into a memory, power is derived from current transformers drawing energy from current flow to a load and the electronics are protected from high voltage caused by heavy current flow to the load, optical isolators are used for the circuit breaker to communicate with external equipment, a multi-turn resistor adjusts an external test voltage for testing the circuit breaker system, in the event that there is no load or a load drawing insufficient current to provide power for the electronics the circuit breaker may be externally powered to provide readout of electrically erasable programmable read only memory, the microprocessor reads setting switches and a multiplier plug. Also the microprocessor is capable of digitizing selected quantities frequently and of digitizing other quantities less frequently. A second microprocessor permits one microprocessor to sample voltage and current rapidly for metering purposes, and the second microprocessor operates other functions.

    Abstract: An operator interface panel assembly is used with a programmable logic controller. Through the use of a printed wired circuit board, a wide variety of input and output components that must be accessible to an operator can be assembled by the user at the location of the installation rather than at the point of manufacture. The assembly can be easily reconfigured without costly rewiring of the installation. The same switch or pilot light position can accommodate a variety of one and two pole switches without hardware modification.

The base and cover/lens provide physical protection for the indicator light and the switch mechanism. The base also includes a passage for retaining the actuator and permitting it to communicate with the switch mechanism.

    Abstract: A processor-based tripping system uses a precise three phase current detection circuit using a minimal number of components. A set of current sensors is situated adjacent the current path to sense respective phases of current therein. The current sensors provide respective current signals therefrom which are fed to a ground fault transformer. The ground fault transformer includes input inductors connected to respective ones of the current sensors such that current flowing through each respective current sensor also flows through one of the input inductors. An output inductor in the ground fault transformer is coupled with the input inductors for adding the current signals from the current sensors and for producing an output current signal in the presence of a ground fault. The output current signal is then rectified to provide a rectified signal corresponding to the output current. The processor receives the rectified signal to detect the ground fault in the three phase current path and provides a trip signal to a solenoid to break the current path. The ground fault transformer also includes a test input inductor for receiving an external AC signal to simulate a ground fault.

    Abstract: A current interrupter in which a first movable, insulating, gear carries a contact blade. The blade extends out from this movable gear and forms a contact which makes and breaks with a stationary contact upon movement of the gear. A second insulating gear has a set of teeth which engage the teeth on the first gear. The second gear has a cavity into which the extended contact fits. Movement of the first gear in a direction to break the contact, causes the engaged teeth to drive the extended contact into the cavity, thereby insulating the movable contact from the stationary contact. The interlocking gear teeth create a tortuous path for the arc and provide a large over surface distance for dielectric strength.

    Abstract: A circuit breaker drawout arrangement includes a drive mechanism for moving a circuit breaker along a pair of rails between a Connect and a Disconnect position by means of a drive tool. A torque limited clutch permits a lower maximum torque when moving the breaker to the Connect position and a greater maximum torque when moving from the Connect position to the Disconnect position. In one embodiment the clutch is formed by a pair of oppositely orientated unidirectional roller clutches in the drive nut and in another by a ball and detent arrangement in the drive nut.
