ENHANCED CIRCUIT BREAKERS AND CIRCUIT BREAKER PANELS AND SYSTEMS AND METHODS USING THE SAME

摘要

A circuit breaker system (500) integrated into a package including an input for coupling to an external electrical power source, an output for coupling to an external electrical circuit, and a current path selectively coupling the input and the output. A mechanical circuit breaker mechanism (502) interrupts electrical power flow through the current path in response to a current exceeding a predetermined value. A trip solenoid (503) causes the mechanical circuit breaker mechanism to interrupt electrical power flow through current path in response to a control signal. Voltage and current sensors (506) measure voltage and current values of the electrical power flowing through the current path and a microprocessor (501) selectively generates the control signal in response to the measured voltage and current values, along with and a control profile stored in memory, to energize the solenoid and cause the mechanical circuit breaker mechanism to interrupt the electrical power.
