Description
Overview
The Eaton Bussmann 160MO9-660 is a bolted-type BS88 fuse link from the Bussmann MO9 series, rated 160A at 660/690V AC with an 80 kA breaking capacity. Classified as Class gG under IEC 60269-2 and BS88 Part 2, this fuse link provides full-range overcurrent protection for cables, busbars, and connected equipment in low voltage power distribution systems. Its single-slot tag type and BS Size B2 form factor make it a direct-fit solution for standard BS88-compatible fuse holders and switch-fuse gear commonly installed in Indian industrial facilities.

Applications & Selection Guide
The 160MO9-660 is specified for general purpose overcurrent protection in low voltage switchgear panels, motor control centres (MCCs), and distribution boards where the prospective short-circuit current can reach up to 80 kA. Its 160A rating positions it as a feeder or sub-main fuse in industrial distribution systems fed from 630 kVA to 1000 kVA transformers typically found in Indian manufacturing plants, textile mills, cement works, and process industries across Tamil Nadu, Maharashtra, Gujarat, and Andhra Pradesh.
Class gG fuses provide full-range protection — meaning they will operate under both sustained overloads and high-magnitude short-circuit faults. Panel builders and electrical contractors specifying protection for cable feeders, busbar trunking tap-off points, or transformer secondary circuits will find the 160A rating appropriate for copper conductors in the 70–120 mm² range depending on installation method. The 660/690V rating ensures the fuse is fully rated for standard Indian 415V three-phase systems as well as higher-voltage drives and equipment.
In India, this product is widely used by panel builders in Coimbatore, Chennai, Pune, and Ahmedabad constructing MCC panels, power control centres, and LV distribution boards for the automotive, pharmaceuticals, food processing, and infrastructure sectors. Consulting engineers should verify the fuse carrier and base rating is compatible with the B2 blade size before specifying this catalog number.

Frequently Asked Questions
What does Class gG mean for the 160MO9-660 fuse link?
Class gG denotes a full-range general purpose fuse that is designed to interrupt all fault currents from the minimum fusing current up to its rated breaking capacity of 80 kA. Unlike motor-rated or back-up fuses, a gG fuse will operate reliably under both prolonged overloads and bolted short-circuit faults, making it the correct choice for cable and distribution circuit protection in switchgear panels and distribution boards.
Is the 160MO9-660 suitable for 415V three-phase systems used in India?
Yes. The 160MO9-660 is rated at 660/690V AC, which fully covers the 415V three-phase (line-to-line) systems standard in India. A fuse rated at a higher voltage than the system voltage is always permissible and provides the same protection characteristics. The 660/690V rating also makes this fuse compatible with 690V class variable frequency drives and imported equipment used in Indian industrial plants.
What is BS Size B2 and which fuse carriers accept this fuse?
BS Size B2 is a standardized blade dimension defined under BS88 Part 2 that corresponds to the physical size of the fuse link’s end tags and blade. Fuse carriers, bases, and switch-fuse disconnectors designed for BS88 B2 size fuses will accept the 160MO9-660 directly. It is important to confirm both the BS size and the tag type (single slot in this case) when selecting a matching fuse carrier to ensure correct mechanical fit and electrical contact.
Can the 160MO9-660 be used for motor circuit protection?
While Class gG fuses can provide overcurrent protection in circuits supplying motors, they are primarily specified for cable and general distribution circuit protection. For motor branch circuits where high starting currents must be tolerated without nuisance blowing, Class aM (motor-rated) fuses are typically recommended in conjunction with overload relays. The 160MO9-660 may be applied on the upstream feeder side of an MCC feeding multiple motor loads, but the design engineer should verify selectivity and coordination with downstream protective devices.
What is the breaking capacity of the 160MO9-660 and why does it matter?
The 160MO9-660 has a rated breaking capacity of 80 kA, which means it can safely interrupt fault currents up to 80,000 amperes without rupture, fire, or loss of containment. This is critical for installations located close to large transformers or main LV busbars where prospective short-circuit currents are high. Engineers must always verify that the selected fuse’s breaking capacity equals or exceeds the maximum prospective short-circuit current at the point of installation.
