Description
Overview
The Eaton Bussmann 10HO7-660 is part of the Bussmann HO7 series of BS88 low voltage fuse links, engineered for general-purpose overcurrent protection in demanding industrial environments. Rated 10 A at 660/690 V AC with an 80 kA breaking capacity, this bolted-type fuse link conforms to BS88 Part 2 and IEC 60269-2, making it a recognised solution for panel builders, OEMs, and electrical contractors across India. Its Class gG characteristic provides full-range protection covering both overload and short-circuit conditions in a single device.
Key Features

Applications & Selection Guide
The 10HO7-660 is the right choice when you need reliable branch-circuit or equipment protection in low voltage switchgear panels, motor control centres (MCCs), and distribution boards operating at up to 660/690 V AC. Its 10 A rating suits the protection of small motors, control transformers, instrumentation feeders, and auxiliary circuits where a cost-effective, standards-compliant fuse link is preferred over a miniature circuit breaker.
The Class gG characteristic means this fuse provides full-range protection — it will clear sustained overloads as well as high-magnitude short-circuit faults up to 80 kA. Engineers specifying for BS88-compliant panels should confirm that the upstream supply’s prospective short-circuit current (PSCC) does not exceed 80 kA at the point of installation. The A2 bolted-type form factor must be matched to an appropriate BS88 A2 fuse base or carrier for safe operation.
In India, these fuse links see widespread use in pharmaceutical manufacturing plants, textile mills, automotive component factories, cement and chemical process industries, and data centre UPS distribution boards — sectors where Coimbatore and Tamil Nadu have a significant industrial footprint. They are equally specified by panel builders supplying export orders that require IEC 60269-2 certification with CE marking.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 10HO7-660?
Class gG denotes a general-purpose, full-range fuse. The ‘g’ prefix means the fuse is rated to break any current that causes it to operate, from the minimum-fusing current right up to its full 80 kA breaking capacity. The second ‘G’ indicates general application — covering both overload protection and short-circuit protection in a single device. This makes the 10HO7-660 suitable for protecting cables, distribution circuits, and motor branch circuits without needing a separate overload relay at the fuse stage.
Is the 10HO7-660 suitable for 415 V AC systems used in India?
Yes. The 10HO7-660 is rated at 660/690 V AC, which comfortably covers the standard 415 V AC (line-to-line) three-phase supply used across Indian industrial installations. Operating a 660 V rated fuse link at 415 V is well within its design envelope and does not affect its protection performance or lifespan. It is also suitable for higher-voltage 600 V or 690 V systems used in export panels or specific industrial drives.
What fuse holder or base is compatible with the A2 bolted-type 10HO7-660?
The 10HO7-660 requires a BS88 A2-size fuse base or carrier designed for the bolted-type connection. The closed-slot tag type must be matched to a holder with the corresponding closed-slot tag receptacle to ensure secure mechanical and electrical contact. Eaton Bussmann manufactures a range of compatible BS88 A2 fuse bases, DIN-rail carriers, and fuse switch disconnectors. Contact Shansen Enterprises with your panel layout details and we will recommend the correct matching holder from our Eaton Bussmann portfolio.
What is the breaking capacity of the 10HO7-660 and why does it matter?
The 10HO7-660 has a breaking capacity of 80 kA. This is the maximum prospective short-circuit current the fuse can safely interrupt without rupturing or causing collateral damage. Before installing any fuse, the engineer must verify that the prospective short-circuit current (PSCC) at the installation point does not exceed this value. In most Indian LV distribution systems fed from standard distribution transformers, the PSCC at panel incomer level is well below 80 kA, so the 10HO7-660 provides an adequate safety margin for the vast majority of applications.
Does the 10HO7-660 carry RoHS compliance and is it CE marked?
Yes. The Eaton Bussmann 10HO7-660 is both CE marked and RoHS compliant, confirming that it meets European Union directives on electrical safety and restriction of hazardous substances. This is particularly relevant for panel builders in India manufacturing switchgear or distribution boards destined for export to European markets, and for projects where environmental or regulatory documentation is required during commissioning audits.
