Abstract
A trigger device for a power switch includes a bi-metal which is arranged near to a current path of a power switch in order to control triggering, as well as a bi-metal mounting device into which the bimetal is inserted and which is designed to enclose the bi-metal, in an arrangement substantially parallel to a current path of a power switch, such that heat radiated from the current path heats the bi-metal more or less across its whole length.
Claims15
A trigger device for a power switch, the device comprising:
- a bimetal, arranged near to a current path of a power switch, in a configuration so as to control triggering of the power switch;
- and
- a bimetal mounting device into which the bimetal is inserted,
- wherein the bimetal mounting device is configured to enclose the bimetal in an arrangement substantially parallel to a current path of the power switch such that heat radiated by the current path can heat the bimetal almost across a whole length of the bimetal, and such that the bimetal is shielded from one or more ambient influences,
- wherein the bimetal mounting device is configured to fully encloses the current path and the bimetal,
- wherein the current path and bimetal can be accommodated in a common housing formed by the bimetal mounting device, and
- wherein the bimetal mounting device includes a base on which the bimetal is attached at a foot thereof.
