Description
Overview
The Eaton Bussmann 32HO7-660 is a bolted-type BS88 low voltage fuse link rated 32 A at 660/690 V AC, belonging to the Bussmann HO7 series. Classified as Class gG under IEC 60269-2 and BS88 Part 2, it provides full-range overcurrent protection for cables, busbars, and equipment in low voltage power distribution systems. Its 80 kA breaking capacity makes it suitable for high fault-current environments found in industrial plants across India.
Key Features

Applications & Selection Guide
The 32HO7-660 is well suited for protecting outgoing feeder circuits, cable runs, and equipment in low voltage switchgear panels and distribution boards operating at up to 660/690 V AC. Its Class gG rating makes it the standard choice for general purpose protection where both overload and short-circuit protection of conductors is required — as opposed to Class aM fuses which protect motor branch circuits against short circuits only.
In Indian industries such as textile manufacturing, automotive component plants, cement processing facilities, and infrastructure projects around Coimbatore and across Tamil Nadu, this fuse link is routinely specified in MCC panels, PCC panels, and feeder pillars where BS88 fuse systems are preferred for their compact size and high breaking capacity. The 32 A rating covers branch circuit protection for smaller drives, transformer secondaries, and distribution sub-circuits.
When selecting this fuse, confirm that the fuse carrier or switch-disconnector installed in your panel accepts BS88 A2 size with a closed-slot tag. Verify the prospective short-circuit current at the point of installation does not exceed 80 kA. For motor protection applications above 32 A or where selectivity with upstream devices is critical, consult Shansen Enterprises for the correct HO7 series rating or alternative Bussmann BS88 variants.

Frequently Asked Questions
What does Class gG mean for the 32HO7-660 fuse link?
Class gG (general purpose, full-range) means the fuse is capable of breaking any current that causes it to operate, from the minimum fusing current up to the rated breaking capacity of 80 kA. Unlike Class aM fuses which only protect against short circuits, a gG fuse also protects cables and equipment against sustained overloads. This makes the 32HO7-660 appropriate for general distribution circuits where both overload and fault protection of conductors is required per IEC 60269-2.
Is the 32HO7-660 suitable for 415 V AC systems used in India?
Yes. The 32HO7-660 is rated 660/690 V AC, which means it is fully suitable for use on 415 V AC three-phase systems — the standard industrial supply voltage in India. A fuse rated for a higher voltage may always be used at a lower system voltage, and the electrical performance characteristics including breaking capacity remain valid at 415 V. There is no derating required for standard Indian LV distribution applications.
What fuse carrier or base is compatible with the 32HO7-660?
The 32HO7-660 is an A2 BS size fuse link with a closed-slot tag and bolted termination. It is designed to fit BS88 A2 fuse carriers and switch-disconnectors that accept closed-slot tag fuse links. Common compatible bases include Eaton Bussmann BS88 A2 fuse holders and appropriately rated switch-fuse units designed for the HO7 series. Always verify the fuse carrier datasheet to confirm physical and electrical compatibility before installation.
What is the breaking capacity of the 32HO7-660 and why does it matter?
The 32HO7-660 has a breaking capacity of 80 kA. This is the maximum prospective fault current the fuse can safely interrupt without rupture or hazard. In industrial LV switchgear close to transformers or main distribution boards, prospective fault currents can be very high. Specifying a fuse with adequate breaking capacity — in this case 80 kA — ensures the device can clear the fault safely, protecting personnel and equipment. Always compare the breaking capacity against the calculated prospective short-circuit current at the installation point.
Can the 32HO7-660 be used for motor circuit protection?
The 32HO7-660 is a Class gG fuse, which provides full-range overcurrent protection including overload protection. While gG fuses can be used in motor circuits, Class aM fuses are more commonly specified for motor branch circuit protection because they are designed to withstand motor starting inrush currents without nuisance operation. If your application requires motor circuit protection, contact Shansen Enterprises to identify the appropriate Bussmann aM-rated fuse or a coordinated motor starter solution from the Eaton range.
