Bussmann FNQ-1/4 Fusetron Time-Delay Midget Fuse, 500V

Bussmann FNQ-1/4 Fusetron Time-Delay Midget Fuse, 500V

The Bussmann FNQ-1/4 is a Fusetron time-delay midget fuse rated for 500V, engineered for dependable overcurrent protection in electrical circuits and equipment. As part of the Bussmann FNQ Fusetron series, this midget fuse uses a time-delay fuse design intended to ride through brief current surges while still opening reliably under sustained overload conditions. Its compact midget fuse form factor allows it to be used in space-constrained fuse blocks, holders, and control panels where standard-size fuses will not fit. The FNQ-1/4 is identified by its Bussmann model number and 500V voltage rating, making it easy to specify as a like-for-like replacement in existing fuse installations. Fuses like the FNQ-1/4 are commonly specified by electricians and panel builders who need a direct, code-compliant replacement for existing midget-style fuse holders.
