Electrical installation appartus having a temperatur controling device

摘要

The electrical installation (2) has cable connections (3). The temperature is detected by a temperature monitoring device (15) which cuts off the circuit when the temperature exceeds a predetermined threshold. The temperature monitoring circuit is connected to a bus coupler (7) which is also connected to a cut-off device (5). The installation is formed with a module (12) which performs the functions of temperature monitoring, cut-off and bus connection, and is connected to existing current carrying parts via sprung contacts (4). The temperature monitoring device may indicate the temperature. The cut-off device may be remotely controllable via the bus coupler. The cut-off device may be a SiC semiconductor switch.
