Cooper Bussmann FNM-2-8/10 Cartridge Time Delay Fuse 2.8A

Product Description

The COOPER BUSSMANN FNM-2-8/10 is a cartridge-style, time-delay fuse rated at 2.8 amps and 250 volts. It provides overcurrent protection in low-amperage branch circuits and control circuits where momentary inrush currents would otherwise cause nuisance blows with a fast-acting fuse. The time-delay characteristic lets the circuit ride through start-up surges while still protecting against sustained overloads and short circuits. The melamine body measures 1-1/2 inches in overall length and 10.3 mm in diameter, fitting standard fuse holders designed for this form factor. Electricians and HVAC technicians install this fuse in control panels, motor control circuits, and low-voltage equipment.

This fuse is suited for general-purpose applications in residential and light commercial electrical systems. Common install scenarios include control transformer secondary circuits, motor starter control wiring, and other low-amperage circuits requiring time-delay overcurrent protection. The green body color aids quick visual identification during service. It mounts in a standard cartridge fuse holder and is handled as a single-piece unit per package.

Key Features

• 2.8A amperage rating with 250V voltage rating
• Interrupting rating of 100A at 250V and 10 kA at 125V
• Melamine cartridge body, 1-1/2 inches long, 10.3 mm diameter
• Green color coding for fast field identification
• CE Certified, CSA Certified, UL Listed 248-14, and RoHS Compliant

Compatibility

Designed as an OEM-style replacement for standard cartridge fuse holders accepting a 10.3 mm diameter, 1-1/2 inch time-delay fuse in general-purpose low-amperage control and branch circuit applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Verify that the replacement fuse amperage, voltage, and time-delay rating match the original equipment specification before installing. Do not exceed the rated interrupting capacity of the fuse for the circuit it protects.
