Abstract

A test circuit is provided, which is independent of a power supply and which enables a circuit breaker to be tested in a reliable manner. The test circuit includes a test coil which is devoid of electric potential and is wound around a totalizing current transformer. The test coil is preferably short circuited using a test switch and a connectable load. This simulates the occurrence of a residual current. The selection of an appropriate connectable load allows the sensitivity of the current circuit breaker to be tested in an advantageous manner.
