ABSTRACT:
An electronic switch for AC currents has only solid state components, including a main bipolar or unipolar switch circuit to switch AC current from an AC line to a load, at least one current limit circuit, a current measurement circuit, a current range setting circuit, a maximum current setting circuit, and a temperature control circuit. All these circuits are controlled by a control logic circuit intended mainly to open and close the switch circuit by means of a manual command and/or according to signals from the circuits.
