Description
Overview
The Eaton Bussmann 80LO9-660 is a bolted-type BS88 fuse link from the Bussmann LO9 series, engineered for dependable general-purpose circuit protection in low voltage electrical installations. Rated 80A at 660/690V AC with an 80kA breaking capacity and conforming to BS88 Part 2 and IEC 60269-2, this Class gG fuse link is built to handle both overload and short-circuit conditions in industrial distribution systems. Its Centre Tag configuration and BS Size B1 form factor make it a direct-fit solution for standard BS88-compatible fuse bases used widely in Indian switchgear and panel-building applications.

Applications & Selection Guide
The Eaton Bussmann 80LO9-660 is suited for general-purpose overcurrent protection in low voltage electrical systems operating at up to 660/690V AC. Its Class gG characteristic provides full-range protection, meaning it is designed to safely clear faults from small overloads through to maximum prospective short-circuit currents — making it the preferred choice for feeder and distribution circuits rather than dedicated motor-branch protection where Class gM or aM fuses would be selected.
This fuse link is widely used in low voltage switchgear panels (LVSDBs), motor control centers (MCCs), power distribution boards, and industrial control panels. The 80A rating places it in a range commonly required for sub-distribution feeders, transformer secondary protection, and busbar tap-off circuits in medium-scale industrial facilities.
In India, the 80LO9-660 finds application across sectors including textiles, automotive, food processing, pharmaceuticals, cement, steel, and infrastructure projects in Tamil Nadu and beyond. Panel builders and switchgear manufacturers in Coimbatore, Chennai, Pune, and Ahmedabad regularly specify BS88 Class gG fuse links for compliance with IEC-based project specifications. The B1 BS size and centre tag configuration align with standard fuse base hardware, simplifying both new installations and maintenance replacements.

Frequently Asked Questions
What does the Class gG rating on the Eaton Bussmann 80LO9-660 mean?
Class gG stands for general-purpose fuse with full-range breaking capacity. The ‘g’ prefix indicates the fuse can interrupt any current that causes it to melt, from small sustained overloads to the maximum prospective short-circuit current. The ‘G’ suffix denotes general application. This makes the 80LO9-660 suitable for protecting cables, feeders, and distribution circuits in low voltage networks where both overload and short-circuit protection is required in a single fuse element.
What is the breaking capacity of the Eaton Bussmann 80LO9-660 and why does it matter?
The 80LO9-660 has a rated breaking capacity of 80kA. This represents the maximum prospective short-circuit current the fuse can safely interrupt without rupture, arcing, or damage to surrounding equipment. When selecting a fuse for any installation, the breaking capacity must equal or exceed the prospective short-circuit current at the point of installation as determined by the system fault level study. An 80kA breaking capacity is adequate for the vast majority of low voltage industrial distribution points in India.
Is the Eaton Bussmann 80LO9-660 suitable for motor protection applications?
The 80LO9-660 is a Class gG fuse link, which provides general-purpose protection for cables and distribution circuits. While it can protect motor branch circuits to a degree, dedicated motor protection typically calls for Class aM (motor starting) fuses that tolerate high inrush currents during motor starting without nuisance operation. If your application involves direct motor feeder protection with frequent starts or high inrush, consult Shansen Enterprises to confirm the correct fuse class for your specific motor and starting conditions.
What fuse base or holder is compatible with the Eaton Bussmann 80LO9-660?
The 80LO9-660 is a BS Size B1 bolted-type fuse link with a centre tag configuration. It is compatible with BS88-compliant fuse bases and carriers designed for the B1 size. Standard Eaton Bussmann BS88 fuse holders and third-party BS88 B1 fuse bases will accept this fuse link. Always verify the fuse base current rating, voltage rating, and physical size designation before installation. Contact Shansen Enterprises for matched fuse base recommendations and panel hardware sourcing.
Does the Eaton Bussmann 80LO9-660 comply with IEC standards applicable in India?
Yes. The 80LO9-660 is manufactured to BS88 Part 2 and IEC 60269-2, which are the governing international standards for low voltage fuses. It carries IEC certification and is CE marked and RoHS compliant. IEC 60269-2 is widely referenced in Indian industrial and infrastructure projects, and products certified to this standard are accepted by consulting engineers, third-party inspectors, and end clients across Indian industries and government projects.
