Applications & Selection Guide
The Eaton Bussmann 6HO7-660 is the right choice for engineers specifying general purpose cable and circuit protection at 6A in low voltage distribution systems operating up to 660/690V AC. Its Class gG classification means it provides full-range protection — handling both sustained overloads and high-magnitude short-circuit currents up to 80 kA — making it a versatile fit for outgoing feeder circuits, sub-distribution boards, and auxiliary supply protection in motor control centres.
In Indian industrial facilities, this fuse link is commonly specified in switchgear panels for textile mills, auto-component manufacturing, chemical processing plants, and infrastructure projects across Tamil Nadu and other major industrial belts. The A2 BS88 bolted format integrates directly into standard fuse carriers and switch-fuse units widely used by Indian panel builders, ensuring a straightforward retrofit or new-build installation without additional hardware modifications.
When selecting this fuse link, verify that the fuse carrier or holder is rated for BS88 Part 2 A2 bolted fuses and supports the 660/690V system voltage. For motor branch circuits, confirm that the upstream fuse rating coordinates with the motor’s full-load current and starting current characteristics to avoid nuisance tripping while maintaining protection under fault conditions.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 6HO7-660 fuse link?
Class gG stands for general purpose full-range fuse. The ‘g’ prefix indicates it is a full-range fuse capable of breaking any current that causes it to melt, from the minimum fusing current up to the rated breaking capacity of 80 kA. The ‘G’ suffix denotes general purpose application, meaning it protects cables and general distribution circuits against both sustained overloads and short-circuit faults. This makes the 6HO7-660 suitable for a wide range of LV distribution and switchgear applications without needing separate backup protection for short-circuit events.
What is the BS Size A2 and which fuse carriers are compatible with the 6HO7-660?
BS Size A2 is a standardised physical envelope defined under BS88 Part 2 for bolted-type fuse links. The A2 size defines the dimensions of the fuse body and tag, ensuring interchangeability across compatible fuse carriers and holders manufactured to the same standard. The 6HO7-660 uses a closed-slot tag design, so the matching fuse carrier must have closed-slot contacts rated for A2 bolted fuses at 660/690V AC. Always cross-check the fuse carrier’s current and voltage rating against the fuse specification before installation.
Can the Eaton Bussmann 6HO7-660 be used for motor circuit protection in India?
Yes, the 6HO7-660 can be used for motor circuit protection provided the 6A rating is appropriately coordinated with the motor’s full-load current, starting current, and the characteristics of any associated overload relay. Class gG fuses are widely used in motor control centres across Indian industries as backup short-circuit protection, often in combination with a thermal overload relay for sustained overload protection. Confirm coordination with your motor starter design and relevant IS/IEC standards applicable to the installation.
What is the breaking capacity of the 6HO7-660 and why does it matter?
The Eaton Bussmann 6HO7-660 has a rated breaking capacity of 80 kA. Breaking capacity is the maximum prospective fault current that the fuse can safely interrupt without rupturing or causing collateral damage. In Indian industrial installations, particularly those close to transformer secondaries or bus bars with high available fault current, specifying fuses with adequate breaking capacity is a critical safety requirement. An 80 kA rating gives this fuse link broad applicability across most LV distribution scenarios encountered in commercial and industrial panel designs.
Is the Eaton Bussmann 6HO7-660 compliant with Indian electrical standards?
The 6HO7-660 is certified to IEC 60269-2 and BS88 Part 2, both of which are internationally recognised standards widely referenced by Indian electrical regulations and the Bureau of Indian Standards. The fuse is CE Marked and RoHS Compliant, and carries IEC Rated certification. While Eaton Bussmann products are manufactured to IEC standards accepted in India, always confirm specific project or tender compliance requirements with your electrical consultant or the relevant regulatory authority for your installation.
