摘要： A circuit breaker in which the levels of overload currents are detected with increased accuracy and which functions properly even just often its load-connecting contacts are closed. A rectifier circuit converts outputs from current transformers into currents flowing in one direction, the current transformers detecting the currents through main the paths. A power supply circuit and current-detecting resistors are connected in series with the output of the rectifier circuit. Differential amplifiers amplify the potential differences across each resistor. If the power from the power supply circuit is insufficient to operate the differential amplifiers and a timer normally, an inhibiting circuit prevents a switch circuit from being closed.

摘要： An electronic circuit breaker is provided with a plurality of air coils, each of which is coupled to a main circuit and an overcurrent signal integrating circuit which receives the output of the air coil to output an overcurrent signal when the current through the main circuit exceeds a predetermined value. A current signal simulating an overcurrent in the main circuit is fed from an external testing device into a current signal receiving terminal (CST). A test voltage generating resistor (TVGR) is connected between the CST and ground. The current signal flows through the TVGR to develop a test voltage across the TVGR. Thus, the overcurrent signal integrating circuit simulates the overcurrent signal on the basis of the test voltage.
