Abstract (en)
[origin: EP0289447A1] In order to protect isolating devices for heavy-current busbars (1), which have a plug-in connecting contact (9) between the heavy-current busbars (1) and an alarm switch (12, 13), arranged in an insulated manner, against unacceptable heating, an additional system part (14) is provided, of material which melts at a low temperature, and which melts above the normal operating temperature but below the acceptable limit temperature of the isolating device, in particular the connecting contact (9). When the system part (14) melts, the alarm switch (12) thus moves into the position it occupies when the connecting contact is not plugged in. This position change of the alarm switch (12) can be used to trip an external protection device, by means of which, e.g. the current flow through the heavy-current busbars (1) is immediately interrupted and as a result of which the isolating device for heavy-current busbars (1) is protected against unacceptable heating and possible destruction. <IMAGE>
