Abstract

1. Tripping system of an automatic circuit breaker for interrupting a current circuit, having at least one thermo-mechanical transducer (21; 31; 41; 51; 61) of an alloy with form memory, a short-circuit trip (12; 22) and a switching mechanism comprising a release gear which, in the event of an overcurrent, is tripped by the thermo-mechanical transducer (21; 31; 41; 51; 61) or short-circuit trip (12; 22) and interrupts the current circuit, characterised in that the thermo-mechanical transducer (21; 31; 41; 51; 61) is in thermal contact with a heat source, which is located in the current path of the automatic circuit breaker, for example the coil or the yoke of a magnetic short-circuit trip (12; 22), the arm of a dynamic tripping loop (17) or the section of a current-conducting path (20).
