摘要： In a panelboard for controlling current paths through a plurality of associated circuit breakers, a panelboard enclosure includes circuit breakers which each have a side facing a front side of the enclosure and including a multi-sectioned user interface circuit, that is configured to communicate with at least one of the circuit breakers. The interface circuit includes a first circuit section and a second circuit section. The first circuit section is located adjacent the back wall of the enclosure and behind the second circuit section, and the second circuit section includes communication means for allowing an operator at the front of the enclosure to communicate with the circuit breakers. This arrangement minimizes heat in the back of the enclosure, provides control and monitoring functions at the front of the enclosure and allows room for additional circuitry in the back of the enclosure. An automatic interpreter may be included in the enclosure for interpreting a coded message which provides the operator access to control the circuit breakers. Preferably, the coded message is received on a coded key card.

摘要： An electrical distribution system having a plurality of dissimilar protective circuit breakers spaced upstream and downstream along the stream of the system includes a restraint signal interface circuit producing upstream restraint signals to the upstream breakers in response to received downstream restraint signals indicating the state of the downstream circuit breakers. The interface circuit pairs the downstream and upstream restraint signals to have the same electrical parameters and information, ground fault and short-time, content, while different pairs have different parameters and information content. A selection or logic circuit internal of the interface circuit distributes an active information state to all upstream restraint signals carrrying the same information as any one downstream restraint signal in an active information state.

摘要： A circuit breaker system employs a sensor circuit to measure the current flow in a conductor. A microcomputer monitors the current flow and trips a circuit breaker if the measured current flow exhibits certain predetermined characteristics. A power supply circuit generates a regulated output voltage proportional to the measured current flow to supply power to a portion of the circuit breaker system electronics. To protect the portion of the electronics powered by the power supply circuit, the output from the power supply is shorted through a resistance circuit for a predetermined period of time if the magnitude of the measured current flow induces an output voltage in excess of a predetermined level.

摘要： A modular circuit interrupter is arranged for interrupting current in a three-phase circuit path providing current from a three-phase source to a three-phase motor. The interrupter includes a contactor unit arranged to interrupt the circuit path in response to a trip command; a current inducer circuit for providing a current signal having a magnitude corresponding to the current in the circuit path; a fault detection circuit responsive to the current signal, for detecting and communicating power faults in the circuit path; and start and stop motor modules. Respective housings are provided for each of the contactor unit, the fault detection circuit, the start motor module and the stop motor module. A data/power communication bus provides a data communication link between each of the contactor unit, the fault detection circuit, the start motor module and the stop motor module. The data/power communication bus also includes power and ground leads for providing power to the contactor unit and the fault detection circuit. The fault detection circuit sends the trip command over the data communication link, and the contactor unit includes decoding circuitry for responding by interrupting the circuit path.

摘要： A circuit monitoring system for a distributed power network employs waveform capturing techniques for efficient and highly accurate monitoring. The system includes a plurality of circuit monitors and a control station, which is coupled to each of the circuit monitors via a multi-drop communications link. Each of the circuit monitors is disposed adjacent an associated one of the branches in the network for sensing power parameters in the branches and for generating and transmitting data representing the power parameters to the control station The control station is used for generating monitoring commands to each of the circuit monitors to provide the system with full system control and evaluation capability. Each of the circuit monitors also includes EEPROM memory for storing and retaining operational data, sent from the control station, in the absence of power. This allows a microcomputer in the circuit monitor to read the retained data for analyzing the sensed power parameter.
