Description
Overview
The Eaton Bussmann 16HO7-660 is a 16 A, 660/690 V AC bolted-type BS88 fuse link from the Bussmann HO7 series, engineered for reliable overload and short-circuit protection in low voltage electrical installations. With an 80 kA breaking capacity and Class gG classification under BS88 Part 2 / IEC 60269-2, it delivers full-range current limiting performance suited to demanding industrial environments. Shansen Enterprises supplies this fuse link to panel builders, OEMs, and electrical contractors across Coimbatore and India from genuine Eaton stock.

Applications & Selection Guide
The 16HO7-660 is a general-purpose fuse link ideally suited for protecting outgoing feeder circuits, branch circuits, and cable runs in low voltage switchgear assemblies, motor control centres (MCCs), and distribution boards operating at up to 660/690 V AC. At 16 A, it covers small motor starters, control panel sub-circuits, and lighting distribution feeders where reliable overload and short-circuit protection is critical to uptime and personnel safety.
Class gG fuses are full-range current-limiting devices that operate on both overload (thermal) and short-circuit (electromagnetic) fault conditions, making them the correct choice for general cable and equipment protection where no upstream current-limiting fuse is present. Engineers designing co-ordinated protection schemes should verify discrimination ratios against upstream fuses using Eaton’s published time-current characteristic curves for the HO7 series.
In India, this fuse link finds widespread application in textile mills, automotive component plants, pharmaceutical manufacturing, food processing facilities, and infrastructure projects across Coimbatore, Chennai, Pune, Mumbai, and Hyderabad. Panel builders and MCC manufacturers registered under BIS or supplying to PSUs will find the IEC 60269-2 certification and CE marking advantageous for tender compliance.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 16HO7-660?
Class gG stands for general-purpose full-range current-limiting fuse. The ‘g’ prefix indicates the fuse is capable of breaking both overload currents and short-circuit currents up to its rated breaking capacity (80 kA for this device). The second letter ‘G’ denotes general application — primarily cable and circuit protection. This distinguishes it from Class gM or aM fuses, which are motor-rated. For general distribution circuits and feeder protection in switchgear panels, gG is the correct and most widely specified class under IEC 60269-2 and BS88 Part 2.
Is the 16HO7-660 suitable for 415 V AC systems used in India?
Yes. The 16HO7-660 is rated at 660/690 V AC, which means it is fully suitable for use in 415 V AC three-phase systems standard in India. Fuses are always applied at or below their rated voltage, so a 660 V rated fuse link provides additional margin when used in a 415 V system. This makes it a versatile choice for both standard Indian LV panels and higher-voltage industrial installations.
What is the BS Size A2 designation and which fuse bases accept this fuse link?
BS Size A2 is a dimensional classification defined under BS88 Part 2 that specifies the physical size of the fuse link — blade width, tag dimensions, and overall length. Only BS88-compatible A2-rated fuse bases and switch-fuse units will accept this fuse link. Using the correct BS size is critical for safe installation; fitting an incorrect size can result in poor contact, overheating, or failure to interrupt. Shansen Enterprises can help you identify compatible fuse bases and holders from the Eaton Bussmann range if required.
Can the 16HO7-660 be used for motor protection applications?
The 16HO7-660 is a Class gG general-purpose fuse link, which provides full-range protection suitable for cable and circuit protection. While gG fuses can protect motor branch circuits in some configurations, dedicated motor protection typically uses Class aM (motor-rated) fuses, which are designed to withstand motor starting inrush currents without operating unnecessarily. If your application involves direct motor protection at 16 A, consult the Eaton Bussmann time-current characteristic curves or contact Shansen Enterprises for guidance on whether an aM-rated alternative from the HO7 series would be more appropriate.
What certifications and compliance markings does the 16HO7-660 carry?
The Eaton Bussmann 16HO7-660 carries IEC rating under IEC 60269-2, is CE Marked for compliance with applicable European directives, and is RoHS Compliant confirming it is free from restricted hazardous substances. These certifications make it suitable for use in projects requiring documented compliance, including PSU tenders, export panels, and installations governed by international electrical standards. All products supplied by Shansen Enterprises are genuine Eaton Bussmann stock with full traceability.
