Protective switch has melting conductor with melting temperature higher than temperature at its location for normal operation, and lower than the predefined maximum temperature

摘要

The switch has a heat generating device (1) that is augmented in the event of a fault with a melting conductor (3) in the heat generating region's effective area through which a current path passes that contains the heat generating device and/or at least one other augmented heat generating device. The melting temperature of the melting conductor is higher than the temperature occurring at its location for normal operation and lower than the a predefined maximum temperature.
