Key Features

2 A Current Rating

Provides supplemental overcurrent protection for electrical circuits requiring a 2 A time-delay fuse rating, subject to appropriate circuit selection.

250 VAC Voltage Rating

Suitable for compatible AC control and equipment circuits operating within the published 250 VAC voltage rating.

Dual-Element Time-Delay Design

The dual-element construction helps accommodate temporary inrush currents associated with transformers, inductive loads and compatible motor control applications.

Compact Midget Fuse Format

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

Voltage-Specific Interrupting Ratings

Features a 100 A interrupting rating at 250 VAC and a 10 kA interrupting rating at 125 VAC. The available fault current must not exceed the applicable rating.

Nickel-Plated Ferrule Connections

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

Applications

Industrial control power transformer circuits
Inductive electrical control circuits
Circuits with temporary inrush currents
Supplemental protection of compatible motor circuits
Industrial electrical control panels
General-purpose AC electrical equipment
Electrical equipment maintenance and fuse replacement
Compatible 5AG midget fuse holders and fuse blocks

Frequently Asked Questions

What is the Bussmann FNM-2?
It is a 2 A time-delay midget cartridge fuse from the Eaton Bussmann FNM series, intended for supplemental overcurrent protection.

Who manufactures FNM-2?
FNM-2 belongs to the Eaton Bussmann series. Its manufacturer catalog number is FNM-2.

What is the current rating?
The rated current is 2 amperes.

What is the AC voltage rating?
The published AC voltage rating is 250 VAC maximum.

Is FNM-2 a fast-acting fuse?
No. It is a dual-element time-delay fuse intended to accommodate certain temporary inrush currents according to its time-current characteristics.

What is the interrupting rating at 250 VAC?
Eaton specifies a 100 A interrupting rating at 250 VAC for FNM-2.

What is the interrupting rating at 125 VAC?
Eaton specifies a 10,000 A interrupting rating at 125 VAC. This higher value must not be applied to a circuit operating 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-2 have a blown-fuse indicator?
No. The standard FNM-2 is a non-indicating fuse.

What type of terminals does it use?
It uses nickel-plated bronze ferrule end caps for installation in compatible fuse holders and fuse blocks.

Can FNM-2 be used for branch-circuit protection?
The FNM series is intended for supplemental overcurrent protection. Branch-circuit applications require a protective device with the appropriate classification and interrupting capacity.

What should be verified before ordering?
Confirm the FNM-2 model number, 2 A current rating, 250 VAC voltage rating, applicable interrupting capacity, time-delay requirements, physical dimensions and fuse-holder compatibility.
