Abstract
Fault current protection switch, of the type equipped with a test button to close a test current circuit that reacts a trigger of a connection spring located in the secondary circuit of a summation current transformer, forming the conductors to test the primary winding of the summation current converter, characterized in that the test current circuit is formed by a conductive link of a conductor to be tested with the secondary circuit, on one side of a diode, and by another conductor link of the conductor. Another side of the trigger to another driver to test, through a test resistor. (Machine-translation by Google Translate, not legally binding)
