Abstract (en)

[origin: DE19842470A1] An earth-leakage circuit-breaker includes a fault-current release circuit (4) containing a mains voltage independent summation current transformer (2), and a mains current supplied overload release circuit (10). The fault current release circuit (4) and the overload release circuit (10) contains a common release relay (7) for actuating a switch mechanism (8), switching a network of conductors (LN). The overload release circuit (10) specifically comprises an evaluation circuit (14), connected to a temperature sensor (16) as well as being connected in series with a threshold circuit (17), and is used for ascertaining the load condition.
