Description
The Bussmann FNM-2 is a 2-amp, 250VAC time delay midget fuse engineered to deliver dependable overcurrent protection in HVAC control circuits, motor circuits, and a wide range of light commercial and residential electrical applications. The time delay characteristic allows the fuse to withstand harmless inrush currents — such as motor starting surges — without nuisance blowing, while still responding quickly to sustained overloads and short-circuit faults that could damage equipment or create safety hazards.
