Abstract

A bimetal controlled circuit breaker includes a current bus that is electrically connected in series with the bimetal element. The current bus extends parallel to the bimetal element in the deflection plane of the latter and is rigid relative to the bimetal element. The deflection of the bimetal element is supported by the action of electrodynamic forces. In order for the circuit breaker to be suitable for greater current intensities and the effect of the electrodynamic forces to be better utilized, the bimetal element is electrically connected in parallel with a shunt path.
