Fuse Midget 4A FNA Series MPN:FNA-4

Time-delay, indicating midget fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow midget fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have a visual indicator to make it easier to identify blown fuses for replacement.

Midget fuses supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection for lighting, solenoid, motor, and transformer circuits. Also known as 5AG fuses, they have lower interrupting ratings than branch-circuit protectors. They are noncurrent-limiting, so they won't limit exposure to the full magnitude and duration of an overcurrent.
