ABSTRACT OF THE DISCLOSURE A test circuit simulates the operation of a multipole electrical circuit breaker, and includes a pair of auxiliary terminals connected by a connection circuit to the input terminals of a bridge rectifier cell whose output is connected in parallel with the respective out- puts to two other rectifier cells associated with current transformers. A first resistor delivers a first signal proportional to the maximum intensity of the mains cur- rents. Diodes cooperate with a second measuring resistor of a residual earth leakage current discriminator. Re- versing the direction of the test current flow in the test circuit is performed by simply changing the polarity of the test terminals, and enables overcurrent protection and earth leakage protection of the electronic trip device to be checked separately.
