Abstract

2.1 Test devices for earth-fault circuit breakers have the object of closing an auxiliary circuit when a test button is operated, in order to be able to test the operation of the earth-fault circuit breaker. In this case, it must be ensured that the auxiliary circuit cannot be closed in the switched-off state. 2.2 The invention indicates a means by which a test device is combined with an auxiliary circuit and a test button (7) having a contact position display device (6), a switch shaft (1) which is connected to the moving contact (2) additionally being equipped with a bending spring (4) which is used not only as an operating device for the contact position display device (6) but also makes contact with a contact spring (5) of the auxiliary circuit when the contacts (2, 3) are closed. When the contacts (2, 3) are opened, the contact spring (5) cannot make contact with the bending spring (4), so that the auxiliary circuit remains opened even if the test button (7) is operated. 2.3 The test device can be used in all types of earth-fault circuit breakers, but is particularly suitable for earth-fault circuit breakers of narrow construction. <IMAGE>
