The Current-Limiting Power Fuse

1. Current-limiting fuses have been developed and tested which will interrupt a short circuit well before the current reaches the maximum value it would attain were the fuse not present. 2. These fuses have many desirable characteristics such as high interrupting capacity, silent operation, no discharge of any kind during interruption, and practically no pressure generation. 3. Such fuses have an ideal application in the protection of small-capacity circuits connected to high-power buses because the associated devices in the circuit are not subjected to the heavy momentary short-circuit current which would exist were the fuse not present.
