- 17 Abstract An excess voltage protection apparatus (9), in particular for a technical signalling device, for arrangement between an external installation (2) and an internal installation (1), having at least two series terminals (10a, 10b) which are each part of a signal path (12a, 12b), the series terminals (10a, 10b) having connection contacts (13a, 13b, 14a, 14b) for connection to the internal and external installation (1, 2), having a base terminal (11) having a connection for a discharge to earth, and at least one excess voltage protection device (17) which is electrically connected to the series terminals, is characterised in that there is provided a connector housing (23) in which the excess voltage protection device (17) is installed, in that the series terminals (10a, 10b) and the base terminal (11) each have an insertion location (16) for fitting the connector housing (23) of the excess voltage protection device (17) and in that the series terminals (10a, 10b) each have a non-releasable isolating blade (19a, 19b) for temporary separation of the signal paths (12a, 12b). A space saving excess voltage protection apparatus which is simple to operate and has a low failure rate is thereby produced. Fig. 2 14a 24 16 19a 24 13a10Oa F---- ~'13b 1 2b 14 FF ---- 23 9 k---1 |
