Abstract
An electrical fuse assembly includes electrically conductive first and second electrodes, and a bimetallic fuse element. The bimetallic fuse element electrically connects the first and second electrodes. The bimetallic fuse element is configured to disintegrate, and thereby disconnect the first electrode from the second electrode, in response to a current exceeding a prescribed trigger current of the bimetallic fuse element for at least a prescribed duration.
Claims32
An electrical fuse assembly comprising:
- electrically conductive first and second electrodes;
- and
- a bimetallic fuse element electrically connecting the first and second electrodes;
- wherein the bimetallic fuse element is configured to disintegrate, and thereby disconnect the first electrode from the second electrode, in response to a current exceeding a prescribed trigger current of the bimetallic fuse element for at least a prescribed duration.
A fused surge protective device (SPD) module, comprising:
- a first electrical terminal;
- a second electrical terminal;
- an overvoltage protection circuit connected between the first electrical terminal and the second electrical terminal;
- and
- a bimetallic fuse including a bimetallic fuse element connected in series with the overvoltage protection circuit between the first and second electrical terminals.
-52. (canceled)
A protected electrical power supply circuit comprising:
- an overvoltage protection circuit;
- and
- a bimetallic fuse element connected in electrical series with the overvoltage protection circuit;
- wherein the bimetallic fuse element is configured to disintegrate, and thereby interrupt the protected electrical power supply circuit, in response to a short circuit current from the overvoltage protection circuit exceeding a prescribed trigger current of the bimetallic fuse element for at least a prescribed duration.
