Applications & Selection Guide
The Eaton Bussmann NSD20 is engineered for general purpose overcurrent protection in low voltage electrical infrastructure. It is well suited for motor control centres, main and sub-distribution boards, industrial switchgear panels, and building services installations where a 20A, 550V AC fuse with high breaking capacity is required. Industries across India including automotive, textiles, food processing, cement, and infrastructure regularly use BS88 Class gG fuses of this type for both feeder and branch circuit protection.
Class gG fuses provide full-range overcurrent protection — they respond to sustained overloads as well as prospective short-circuit currents up to 80 kA. When selecting the NSD20, ensure the fuse holder is rated for BS Size F1 clip-on tags and that the system prospective short-circuit current at the point of installation does not exceed 80 kA. For motor branch circuits requiring back-up protection only, a Class aR or gR fuse may be more appropriate; consult your Shansen Enterprises technical representative for guidance.
In Coimbatore and across Tamil Nadu, the NSD20 is commonly specified by panel builders and OEMs supplying equipment to pumping stations, compressor skids, packaging lines, and textile machinery. Its RoHS compliance also makes it the preferred choice for equipment exported to European markets.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann NSD20 fuse?
Class gG denotes a general purpose, full-range fuse capable of interrupting all currents from its minimum fusing current up to its rated breaking capacity of 80 kA. Unlike back-up fuses (Class aR or gR), a Class gG fuse like the NSD20 will operate on sustained overloads as well as short-circuit faults, making it suitable for feeder protection and branch circuits where full-range protection is required.
Is the NSD20 suitable for motor protection applications?
The NSD20 is a Class gG general purpose fuse and can be used for motor branch circuit protection when applied in line with IEC 60269-2 guidelines and motor starter coordination requirements. For applications demanding higher motor starting tolerance or back-up only protection, Eaton Bussmann offers Class gR or aR high speed fuses. Contact Shansen Enterprises to confirm the correct fuse rating and class for your specific motor load in Coimbatore or anywhere in India.
What fuse holder is compatible with the Eaton Bussmann NSD20?
The NSD20 uses a BS Size F1 clip-on tag format and requires a compatible BS88 Part 2 fuse holder or carrier designed for F1 clip-on fuses. Eaton Bussmann supplies matching fuse bases and carriers within the NSD series accessory range. Always verify the fuse holder current and voltage ratings are equal to or greater than those of the NSD20 before installation.
Does the NSD20 comply with RoHS and CE requirements?
Yes. The Eaton Bussmann NSD20 is both CE Marked and RoHS Compliant, confirming it meets European Union safety directives and restrictions on hazardous substances. This makes it suitable for use in equipment supplied to European markets and for facilities in India that require internationally compliant components in their electrical panels.
What is the breaking capacity of the NSD20 and why does it matter?
The NSD20 has a breaking capacity of 80 kA, meaning it can safely interrupt fault currents up to 80 kA without rupturing or causing damage beyond the fuse itself. This is a critical specification — always compare the prospective short-circuit current (PSCC) at your installation point against this value. If the PSCC exceeds 80 kA, a higher rated fuse or upstream current limiting device must be used. For typical distribution boards and motor control centres in Indian industrial installations, 80 kA is generally more than adequate.
