Applications & Selection Guide
The EITD20 is well-suited for protecting branch circuits, motor feeders, and distribution busbars in low voltage switchgear assemblies operating on standard 415V AC three-phase systems prevalent throughout Indian industrial and commercial facilities. Its Class gG characteristic ensures full-range overcurrent protection — it will clear faults from small sustained overloads all the way up to high-magnitude short-circuit currents up to 80 kA, making it dependable even in switchboards located close to transformers with high prospective fault levels.
Panel builders and electrical contractors in Coimbatore and across Tamil Nadu commonly specify the EIT Series for motor control centres (MCCs), power distribution boards (PDBs), and sub-distribution panels in textile mills, engineering works, chemical plants, food processing units, and infrastructure projects. The bolted connection design and open slot tag make this fuse particularly practical in busbar-mounted fuse bases where secure termination and quick identification during routine maintenance are priorities.
When selecting this fuse, verify that the upstream fuse or MCCB provides adequate back-up discrimination and that the fuse base or fuse holder is rated for BS88 Part 2, BS Size A1 fuse links. For motor protection applications, confirm that the fuse’s time-current characteristic is co-ordinated with the motor’s starting current profile to avoid nuisance operation during direct-on-line starts.

Frequently Asked Questions
What does Class gG mean for the EITD20 fuse link?
Class gG (general purpose, full range) means the EITD20 is capable of interrupting all overcurrents from the minimum fusing current (a small sustained overload) up to the maximum rated breaking capacity of 80 kA. Unlike back-up fuses, a gG fuse does not require a series device to clear low-level overloads — it handles the full spectrum of fault conditions on its own, making it the standard choice for feeder and distribution circuit protection in low voltage panels.
Is the EITD20 suitable for motor protection applications in 415V AC systems?
Yes, the EITD20 can be used in motor circuit applications on 415V AC systems, but the selection must account for the motor’s full-load current, starting current, and starting duration. A 20A Class gG fuse is typically appropriate for motors with a full-load current below 20A and moderate starting conditions. For heavy-duty or frequent-start applications, a Class aM (motor duty) fuse may be more suitable to avoid nuisance tripping during extended starts. Shansen Enterprises can assist with application-specific fuse co-ordination advice.
What fuse base or fuse holder is compatible with the EITD20?
The EITD20 is a BS88 Part 2, BS Size A1 bolted-type fuse link. It must be installed in a fuse base or fuse holder designed for BS88 Part 2, A1 size, with appropriate bolted terminal connections. Always verify that the fuse base’s current and voltage ratings meet or exceed the circuit requirements. Shansen Enterprises can recommend compatible Eaton Bussmann fuse bases and carriers for your specific panel or switchgear design.
What standards and certifications does the EITD20 comply with?
The EITD20 complies with BS88 Part 2 and IEC 60269-2, which are the internationally recognised standards for low voltage fuse links. It is IEC Rated, CE Marked, and RoHS Compliant. These certifications confirm that the product meets rigorous performance, safety, and environmental requirements, making it acceptable for use in panel designs intended for both Indian and export markets where IEC-compliant components are specified.
Can the EITD20 be used in distribution boards for commercial buildings in India?
Yes. The EITD20 is well suited for final sub-circuit and feeder protection in commercial building distribution boards operating on 415V AC three-phase supply. Its 20A rating and 80 kA breaking capacity make it appropriate for lighting feeders, small power circuits, and sub-distribution panels in offices, hospitals, shopping complexes, and industrial facilities across India. Ensure the distribution board’s busbar and fuse base ratings are matched to the installed fuse link.
