Description
Overview
The Eaton Bussmann NSD25 is a Class gG low voltage fuse link from the Bussmann NSD series, built to BS88 Part 2 and IEC 60269-2 standards. Rated 25 A at 550 V AC with an 80 kA breaking capacity, it provides dependable overcurrent and short-circuit protection for general purpose low voltage applications. Its clip-on tag design makes it particularly suited to panel builders and maintenance engineers working in space-constrained switchgear and distribution installations throughout India.

Applications & Selection Guide
The NSD25 is the right choice for general purpose overcurrent protection in low voltage switchgear panels, motor control centres (MCC), and distribution boards where a 25 A fuse link with clip-on convenience is required. Its Class gG characteristic provides full-range protection — handling sustained overloads through to bolted short-circuit faults — making it appropriate for feeder circuits, bus-bar protection, and sub-distribution in both new installations and retrofit upgrades.
With a 550 V AC rating and 80 kA breaking capacity, the NSD25 operates comfortably within Indian 415 V three-phase industrial systems and satisfies the fault level requirements of most LV distribution switchboards. The BS88 clip-on format is widely specified by panel builders and electrical contractors across Tamil Nadu, Maharashtra, Gujarat, and other major industrial states where IEC and BS88 hardware is standard.
Typical Indian industry segments include textile mills, automotive component plants, food processing units, cement and chemical facilities, data centre power distribution, and infrastructure projects. When coordinating protection schemes, pair the NSD25 with appropriately rated upstream fuse links or MCCBs to ensure selectivity across the full fault current range.

Frequently Asked Questions
What does Class gG mean for the NSD25 fuse link?
Class gG indicates a general purpose, full-range fuse link that provides protection against both overload currents and short-circuit currents across its entire breaking range. Unlike aM (motor protection) fuses that only protect against short circuits, the gG classification means the NSD25 will operate on sustained overloads as well, making it suitable for feeder protection, distribution boards, and general circuit protection in LV switchgear panels.
Is the NSD25 suitable for use on Indian 415 V three-phase supplies?
Yes. The NSD25 is rated at 550 V AC, which provides a comfortable voltage margin above the standard Indian three-phase supply of 415 V (line-to-line) and even 440 V systems. This margin also accommodates voltage fluctuations common in industrial environments across India, ensuring the fuse operates safely within its rated parameters.
What is the difference between a clip-on tag fuse and a standard BS88 fuse link?
A clip-on tag fuse like the NSD25 uses a flat metal tag that clips directly into a compatible fuse carrier or base without requiring bolted connections, making installation and replacement faster and tool-free. Standard BS88 fuse links typically use bolted or blade-type end caps. The clip-on format is favoured in panel builds where rapid fuse changes during maintenance shutdowns are a priority. Always ensure the fuse base or carrier is rated and designed for the clip-on F1 size.
Can the NSD25 be used for motor protection in an MCC panel?
The NSD25 carries a Class gG rating, which offers full-range protection including overload protection. While gG fuses can be used in motor circuits, Class aM (motor protection) fuses are generally preferred for direct-on-line motor starters because they are designed to withstand motor starting inrush currents without nuisance tripping. If motor starting inrush is a concern, consult Shansen Enterprises for guidance on selecting the appropriate Eaton Bussmann aM series fuse link for your motor rating.
What certifications does the Eaton Bussmann NSD25 carry?
The NSD25 is IEC Rated, CE Marked, and RoHS Compliant. IEC certification confirms that the fuse meets the performance and testing requirements of IEC 60269-2 and BS88 Part 2. CE Marking ensures conformity with applicable European directives, and RoHS compliance confirms the product is free from restricted hazardous substances — important for projects with environmental and export requirements.
