Description
Overview
The Eaton Bussmann NSD2 is a BS88 clip-on fuse link from the trusted Bussmann NSD series, rated 2 A at 550 V AC with an 80 kA breaking capacity and Class gG characteristics. Designed for general-purpose low voltage circuit protection, it fits BS Size F1 clip-on fuse carriers widely used in switchgear panels, motor control centres, and industrial distribution boards across India. Its compact clip-on tag format enables fast, tool-friendly replacement, minimising downtime in critical installations.

Applications & Selection Guide
The NSD2 is the preferred choice for protecting low-current circuits — control wiring, auxiliary supplies, instrumentation feeders, and small motor branches — within low voltage switchgear assemblies and motor control centres operating at up to 550 V AC. Its Class gG characteristic provides full-range protection, meaning it will respond to both sustained overloads and instantaneous short-circuit currents without requiring a separate backup fuse, simplifying panel design and reducing component count.
In the Indian industrial context, the NSD2 is widely specified in panel-building projects for sectors including textiles, automotive manufacturing, pharmaceuticals, food processing, and building services. It is equally suitable for retrofitting existing BS88 F1 clip-on fuse holders in legacy distribution boards where space and form factor are constrained. Engineers specifying fuses for 415 V three-phase TPN boards should confirm that the prospective short-circuit current at the point of installation does not exceed 80 kA, which covers the vast majority of LV distribution applications in India.
When selecting the correct fuse rating, choose the NSD2 for individual circuit protection of small loads up to 2 A. For higher amperages in the same Bussmann NSD clip-on series, companion catalog numbers are available across the full range — Shansen Enterprises can advise on the correct rating for your specific load calculation and coordination requirements.

Frequently Asked Questions
What does the Class gG rating mean for the Eaton Bussmann NSD2?
Class gG denotes a general-purpose, full-range fuse that provides overcurrent protection across the complete range from overload currents through to maximum short-circuit currents. The lowercase ‘g’ indicates full-range breaking capacity, and ‘G’ denotes general-purpose application. This means the NSD2 will reliably interrupt any fault current from a small sustained overload up to 80 kA without requiring a separate backup fuse, making it a self-contained protection device for most low voltage circuits.
What is the difference between the clip-on tag type and a standard blade or bolted fuse link?
The clip-on tag format used by the NSD2 is designed to snap into a compatible spring-loaded fuse carrier without bolts or screws, allowing fast replacement during maintenance or after a fault. This reduces panel downtime significantly compared to bolted fuse links. The F1 size clip-on format is common in British-standard switchgear and distribution boards found widely in India, particularly in installations designed to BS or IEC standards. Always ensure the fuse carrier is rated for clip-on F1 BS88 fuses before fitting the NSD2.
Is the NSD2 suitable for use in 415 V three-phase Indian power systems?
Yes. The NSD2 is rated at 550 V AC, which comfortably covers standard 415 V three-phase (line-to-line) and 240 V single-phase supplies used throughout India. The higher voltage rating provides an additional safety margin and makes the NSD2 suitable for slightly elevated supply voltages that can occur in industrial environments. Always verify the actual prospective short-circuit current at the point of installation does not exceed the 80 kA breaking capacity of this fuse.
Can the NSD2 be used for motor protection, or is a different fuse class required?
The NSD2 with its Class gG characteristic is suitable for protecting motor branch circuits where the motor starting current does not cause nuisance fuse operation at the 2 A rating. For motors with high inrush starting currents, a Class aM (motor-rated) fuse may be more appropriate as it tolerates starting surges without operating. However, for very small motors or for providing backup short-circuit protection upstream of a motor starter, the gG-rated NSD2 is a valid selection. Consult Shansen Enterprises for application-specific fuse coordination advice.
What fuse carrier or fuse base is compatible with the NSD2?
The NSD2 requires a BS88 clip-on fuse carrier or fuse base designed for the F1 BS size with clip-on tag accommodation. Eaton Bussmann and other manufacturers produce compatible F1 clip-on fuse carriers in both DIN-rail mounted and panel-mounted configurations. Shansen Enterprises can help identify and supply the correct matching fuse carrier alongside the NSD2 fuse links to ensure a complete, compliant assembly.
