Bussmann FNM-1-1/2 Miniature Fusetron Time-Delay Fuse

Bussmann FNM-1-1/2 Miniature Fusetron Time-Delay Fuse

The Bussmann Miniature Fusetron Time-Delay Fuse shown above is part of Bussmann's recognized FNM Series, a line of compact, cartridge-style fuses built for dependable overcurrent protection in space-constrained electrical and control circuits. As a Fusetron-branded fuse, it is designed around Bussmann's time-delay fuse technology, helping circuits ride through momentary inrush and surge currents without nuisance opening under normal starting conditions. The miniature cartridge form factor makes it a practical fit for equipment panels, control cabinets, and appliances where board space and fuse holder dimensions are limited. Bussmann fuses are manufactured to consistent quality standards, giving specifiers and maintenance teams a dependable option when matching an existing FNM Series fuse already in service.
