Key Features

800 mA Current Rating

Provides supplemental overcurrent protection for electrical circuits requiring a 0.8 A time-delay fuse rating.

250 VAC Voltage Rating

Designed for compatible AC control and equipment circuits operating within the specified 250 VAC voltage rating.

Dual-Element Time-Delay Design

Helps accommodate certain temporary inrush currents associated with transformers, motors and inductive loads according to the published fuse time-current characteristics.

Compact Midget Cartridge Format

Uses a nominal 10.3 x 38.1 mm cylindrical fuse design for installation in appropriately rated and dimensionally compatible holders.

Voltage-Specific Interrupting Ratings

Features an interrupting rating of 35 A at 250 VAC and 10 kA at 125 VAC. The applicable rating must be checked against the prospective fault current at the actual system voltage.

Ferrule End Connections

Nickel-plated bronze end caps provide electrical contact surfaces for compatible midget fuse holders and fuse blocks.

Applications

Industrial control power transformer circuits
Low-current inductive control circuits
Circuits with temporary inrush currents
Supplemental protection of compatible motor control circuits
Industrial electrical control panels
Electrical equipment control and instrumentation circuits
Electrical equipment maintenance and replacement
Compatible 5AG midget fuse holders and fuse blocks

Frequently Asked Questions

What is the Bussmann FNM-8/10?
It is an 800 mA time-delay midget fuse from the Eaton Bussmann FNM series, intended for supplemental overcurrent protection.

Who manufactures FNM-8/10?
FNM-8/10 is an Eaton Bussmann series fuse. The manufacturer part number is FNM-8/10.

What is the current rating?
The rated current is 0.8 A, equivalent to 800 mA or eight-tenths of an ampere.

What is the AC voltage rating?
The specified voltage rating is 250 VAC.

Is FNM-8/10 a fast-acting fuse?
No. It is a dual-element time-delay fuse intended to accommodate certain temporary inrush currents according to its operating characteristics.

What is the interrupting rating at 250 VAC?
The published interrupting rating is 35 A at 250 VAC.

What is the interrupting rating at 125 VAC?
The published interrupting rating is 10,000 A at 125 VAC. This higher interrupting rating does not apply at 250 VAC.

What are the physical dimensions?
The nominal dimensions are 10.3 mm in diameter and 38.1 mm in length, corresponding to the 5AG midget cartridge format.

Does FNM-8/10 have a blown-fuse indicator?
No. The standard FNM-8/10 is non-indicating.

What type of terminals does this fuse use?
It uses ferrule-style end caps made of nickel-plated bronze for installation in compatible fuse holders.

Can FNM-8/10 be used for branch-circuit protection?
The FNM series is designed for supplemental overcurrent protection. Applications requiring branch-circuit protection must use appropriately classified protective devices.

What should be verified before ordering?
Confirm the exact FNM-8/10 model number, 800 mA current rating, 250 VAC voltage rating, voltage-dependent interrupting capacity, time-delay characteristics, physical dimensions and fuse-holder compatibility.
