Circuit breaker for use in cascaded switching arrangement, has register arranged such that register does not directly and indirectly affect switching element when branch is parallely connected to another switching element

摘要

The breaker (18) has switching elements (24, 26) connected between an input terminal (20) and an output terminal (22). A branch including a resistor is connected parallel to the switching element (24), and the element (26) is not connected with the branch. The register is arranged such that the register does not directly and indirectly affect the switching element (26) when the branch is parallely connected to the switching element (24). A bimetal element (46) is connected between the input and output terminals for indirect opening of the element (26) over a latching mechanism.
