Cooper Bussmann FNM-8/10 Time Delay Cartridge Fuse 0.8A

Product Description

The COOPER BUSSMANN FNM-8/10 is a general-purpose time delay cartridge fuse rated at 0.8 amps and 250 volts. It features a melamine body that provides reliable thermal and mechanical durability in demanding electrical environments. The time delay characteristic allows the fuse to tolerate brief inrush currents without nuisance tripping, while still providing overcurrent protection for sensitive circuits. With an interrupting rating of 35 amps at 250 volts and 10 kA at 125 volts, this fuse is suited for control circuits, motor loads, and low-voltage instrumentation panels where precise protection is required. Installation is typically performed by licensed electricians or qualified HVAC and control systems technicians.

This fuse is commonly used in residential and light commercial control panels, HVAC equipment control circuits, motor starters, and low-current instrumentation systems. Its cartridge form factor mounts directly into standard fuse holders, making it a straightforward field replacement or service component. The green-colored body aids in quick visual identification during panel inspection. Applications requiring CE, CSA, UL, or RoHS compliance will find this fuse meets those certification standards.

Key Features

• Time delay design tolerates inrush current without nuisance tripping

Compatibility

Designed as an OEM-style replacement cartridge fuse for standard fuse holders in general-purpose control and low-voltage circuit protection applications.

Installation Notes

Always de-energize the circuit and verify zero voltage with a meter before replacing any fuse. This fuse mounts into a compatible cartridge-style fuse holder and should be matched to the correct amperage and voltage rating for the circuit being protected. Installation must comply with applicable NEC requirements for overcurrent protection. Never substitute a higher-rated fuse in place of the specified amperage.
