Applications & Selection Guide
The EITD50 is the correct choice when you need a standardised, bolted BS88 gG fuse link for general purpose overcurrent and short-circuit protection in 415V AC three-phase systems. It is well suited for outgoing feeders in main LV distribution boards, final sub-circuit protection in motor control centres, and busbar protection in industrial switchgear assemblies. The 80 kA breaking capacity ensures it can safely interrupt even the highest fault currents encountered close to transformer secondary terminals.
Class gG fuses provide full-range protection — they respond to both sustained overloads and instantaneous short-circuit faults, making the EITD50 appropriate wherever a single device must handle the entire prospective current range without a back-up fuse. This contrasts with Class aM fuses, which are motor-duty rated and should not be used as the sole protective device for cables or distribution circuits.
In the Indian industrial context, the EITD50 sees wide use in textile mills, automotive ancillary plants, food processing facilities, pharmaceutical manufacturing units, and commercial complexes across Coimbatore, Chennai, Pune, Ahmedabad, and other industrial centres. Panel builders and electrical contractors sourcing BS88-compliant fuse links for projects meeting IS/IEC standards will find this fuse link a direct-fit solution.

Frequently Asked Questions
What does Class gG mean for the EITD50 fuse link?
Class gG stands for general purpose, full-range fuse. The ‘g’ prefix indicates it is capable of breaking all currents from the minimum fusing current up to the maximum breaking capacity — in the case of the EITD50, up to 80 kA. The ‘G’ suffix denotes general application, meaning it is suitable for protecting cables, distribution circuits, and other general electrical equipment rather than being optimised specifically for motor starting duty. This makes the EITD50 the right selection for feeder and distribution protection in switchgear panels and distribution boards.
Is the EITD50 suitable for use in Indian 415V three-phase LV systems?
Yes. The EITD50 carries a rated voltage of 415V AC, which directly matches the standard three-phase low voltage supply in India (415V line-to-line, 50 Hz). It is compliant with IEC 60269-2 and BS88 Part 2, both of which are internationally recognised standards accepted under Indian electrical regulations for low voltage installations. It is CE marked and IEC rated, making it suitable for use in industrial, commercial, and infrastructure projects across India.
What is the breaking capacity of the EITD50 and why does it matter?
The EITD50 has a breaking capacity of 80 kA. Breaking capacity is the maximum prospective fault current the fuse can safely interrupt without rupturing or causing a hazard. In industrial installations located close to large transformers or in high-fault-level LV networks — common in Coimbatore’s textile and engineering industries — the available short-circuit current can be very high. Selecting a fuse with an adequate breaking capacity ensures that in a fault event, the device operates safely and does not cause damage to surrounding equipment, wiring, or personnel.
Can the EITD50 be used for motor protection applications?
The EITD50 is a Class gG general purpose fuse and is not optimised for motor starting duty. Motor circuits experience high inrush currents during starting — typically 6 to 8 times the full-load current — which a gG fuse may respond to if the starting time is prolonged. For dedicated motor protection, Class aM (motor-duty) fuses from the Eaton Bussmann range are recommended, as they are designed to ride through motor inrush currents without operating. However, the EITD50 can be used as an upstream back-up fuse in a motor circuit provided a suitable overload relay and contactor combination provides the running overload protection downstream.
What fuse holder or base is compatible with the EITD50?
The EITD50 is an A2 BS size bolted-type fuse link. It is compatible with BS88 Part 2 fuse bases, fuse carriers, and switch-fuse units designed for the A2 size with bolted connection hardware. Eaton Bussmann offers a range of matching fuse holders and distribution fuse boards for this size. When in doubt, contact Shansen Enterprises with your panel design details and we will confirm the correct matching fuse base and accessories for your application.
