Key Features

1.5 A Current Rating

Provides supplemental overcurrent protection for electrical circuits requiring a 1.5 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 control power transformers, inductive loads and compatible motor circuits according to published time-current characteristics.

Compact Midget Cartridge Format

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

Voltage-Specific Interrupting Ratings

Features a 100 A interrupting rating at 250 VAC and a 10 kA interrupting rating at 125 VAC. Fuse selection must account for the available fault current at the actual circuit voltage.

Nickel-Plated Ferrule Connections

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

Applications

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

Frequently Asked Questions

What is the Bussmann FNM-1-1/2?
It is a 1.5 A time-delay midget cartridge fuse from the Eaton Bussmann FNM series, intended for supplemental overcurrent protection.

Who manufactures FNM-1-1/2?
FNM-1-1/2 belongs to the Eaton Bussmann series. Its manufacturer catalog number is FNM-1-1/2.

What is the current rating?
The rated current is 1.5 A, equivalent to one and one-half amperes.

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

Is FNM-1-1/2 a fast-acting fuse?
No. It is a dual-element time-delay fuse intended to accommodate certain temporary inrush currents according to its published operating characteristics.

What is the interrupting rating at 250 VAC?
The manufacturer specifies a 100 A interrupting rating at 250 VAC for FNM-1-1/2.

What is the interrupting rating at 125 VAC?
The manufacturer specifies a 10,000 A interrupting rating at 125 VAC. This higher value must not be applied to circuits 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 fuse format.

Does FNM-1-1/2 have a blown-fuse indicator?
No. The standard FNM-1-1/2 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-1-1/2 be used for branch-circuit protection?
The FNM series is intended for supplemental overcurrent protection. Applications requiring branch-circuit protection must use an appropriately classified protective device.

What should be verified before ordering?
Confirm the exact FNM-1-1/2 model number, 1.5 A current rating, 250 VAC voltage rating, voltage-specific interrupting capacity, time-delay characteristics, fuse dimensions and holder compatibility.
