Industrial S101K10A Fuse

BBC Brown Boveri Mini-Stolz S101 permanent fuse, part number S101K10A, is an industrial fuse rated for 10 amperes and described in listings as new. The S101 designation places this device in the Mini-Stolz line, a compact fuse format used in older BBC/Brown Boveri equipment for overcurrent protection. Labeled K10A, the fuse carries a 10 A nominal current rating, providing protection by interrupting the circuit when current exceeds that limit. As a permanent fuse, it is intended to be replaced after any fault event rather than reset, consistent with standard fuse operation for non-re-settable protection devices. This specific S101K10A part is often encountered in vintage catalogs and marketplaces as a direct match for equipment and assemblies that originally used the S101 family, making it a historically appropriate replacement for legacy protection schemes.
