The COOPER BUSSMANN BP/FNM-15 is a Type FNM time-delay cartridge midget fuse rated at 15 amps and 125 volts. It is designed to protect low-amperage control circuits and small electrical equipment from overloads and short circuits. The time-delay characteristic allows temporary inrush currents to pass without nuisance tripping, making it well suited for motor and transformer applications. Each package contains two fuses. Electricians and HVAC technicians install this style of fuse in control panels, HVAC control circuits, and light industrial equipment requiring midget fuse protection.

This fuse is commonly used in residential and light commercial applications where FNM-class midget fuses are specified. Typical installations include HVAC control boards, fan motor circuits, small transformer secondaries, and low-voltage control panels. The carded two-pack format is practical for field service technicians who routinely carry spare fuses for common ratings.

Key Features

Time-delay action tolerates inrush current without nuisance tripping
15-amp rating suits low-amperage control and motor circuits
125-volt AC rating for standard low-voltage control applications
Cartridge midget form factor fits standard midget fuse holders
Two fuses per carded package for field service convenience

Compatibility

Designed as an OEM-style replacement for Type FNM midget fuse applications in HVAC control circuits, light industrial control panels, and other equipment specifying a 15-amp, 125-volt time-delay midget fuse.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician. De-energize and lock out the circuit before removing or installing any fuse. Verify that the replacement fuse rating matches the equipment nameplate and circuit protection requirements exactly. Never substitute a higher-amperage fuse or bypass the fuse holder.
