Key Features

100 mA Current Rating

Provides supplemental overcurrent protection for electrical circuits requiring a 0.1 A time-delay fuse rating.

250 VAC Voltage Rating

Designed for supplemental protection of appropriately specified AC circuits operating at voltages up to 250 VAC.

Dual-Element Time-Delay Design

Helps accommodate temporary inrush currents associated with inductive loads while providing overcurrent protection according to the fuse operating characteristics.

Compact Midget Fuse Format

Uses a 10.3 x 38.1 mm cylindrical cartridge design for installation in compatible fuse holders and fuse blocks.

Voltage-Dependent Interrupting Ratings

Rated to interrupt 35 A at 250 VAC and 10 kA at 125 VAC. Fuse selection must account for the available fault current at the actual system voltage.

Industrial Supplemental Protection

Features melamine tube construction and nickel-plated end caps for supplemental protection of compatible motor, transformer and inductive circuits.

Applications

Industrial control circuit transformers
Low-current inductive control circuits
Circuits with temporary inrush currents
General-purpose supplemental circuit protection
Industrial electrical control panels
Metering and instrumentation circuits
Electrical equipment maintenance and replacement
Compatible midget fuse holders and fuse blocks

Frequently Asked Questions

What is the Bussmann FNM-1/10?
It is a 100 mA time-delay midget fuse from the Eaton Bussmann FNM series, designed for supplemental overcurrent protection.

Who manufactures the FNM-1/10?
FNM-1/10 belongs to the Eaton Bussmann series. Littelfuse FLM is a different fuse series and should not be confused with the FNM manufacturer designation.

What is its rated current?
The rated current is 0.1 A, equivalent to 100 mA or 1/10 ampere.

What is its voltage rating?
The published voltage rating is 250 VAC maximum.

Is FNM-1/10 a fast-acting fuse?
No. It is a time-delay fuse with a dual-element design intended for circuits that may experience temporary inrush currents.

What is the interrupting rating at 250 VAC?
The interrupting rating is 35 A at 250 VAC for the 100 mA version.

What is the interrupting rating at 125 VAC?
The interrupting rating is 10,000 A at 125 VAC. The 125 VAC value must not be applied to a 250 VAC system.

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 fuse format.

Does this fuse have a blown-fuse indicator?
No. The standard FNM-1/10 is a non-indicating fuse.

What materials are used?
The FNM series uses melamine tube construction and nickel-plated end caps. Eaton identifies nickel-plated bronze end caps for this model.

Can FNM-1/10 be used for branch-circuit protection?
The FNM series is classified for supplemental protection. Applications requiring branch-circuit protection need a device with the appropriate classification and interrupting rating.

What should be checked before ordering?
Verify the complete FNM-1/10 model number, 100 mA current rating, 250 VAC voltage rating, available fault current, time-delay requirements, physical dimensions and fuse-holder compatibility.
