Installation switching device i.e. selective main line circuit breaker, has compensation bimetal and adjusting device, which are assigned to main thermo bimetal, where adjusting device holds coupling between compensation and thermo bimetals

摘要

The device (10) has a main current path in which a main thermo bimetal (32) is arranged, where the thermo bimetal acts on a latching area of a latching mechanism by a transmission element. A compensation bimetal (38) and an adjusting device are assigned to the thermo bimetal. The adjusting device holds a coupling between the compensation bimetal and the thermo bimetal. The adjusting device is formed by an adjusting screw (40), and the compensation bimetal is connected with the thermo bimetal. The adjusting screw is formed from an electrically insulating material.
