Applications & Selection Guide
The 200MO9-660 is engineered for general-purpose overcurrent protection in low voltage switchgear panels, motor control centres (MCCs), and distribution boards operating at 660/690 V AC. Its 200 A rating positions it as the primary protection element for feeder circuits, busbar sections, and outgoing ways in industrial and commercial electrical installations where cable and equipment integrity must be maintained under both sustained overloads and high-magnitude short-circuit events.
As a Class gG fuse, the 200MO9-660 provides full-range protection — it will operate under prolonged overload conditions as well as instantaneous short-circuit faults, making it the correct choice wherever a single fuse must handle both scenarios without selectivity aids. Panel builders specifying protection for 415 V three-phase systems should note that the 660/690 V rating provides an adequate safety margin over India’s standard 415 V line-to-line voltage, which is consistent with IEC 60269-2 application guidelines.
In India, this fuse link is widely used across industries including textiles, automotive, food processing, cement, steel, pharmaceuticals, and data centre power distribution — sectors heavily concentrated in Tamil Nadu, Maharashtra, Gujarat, Karnataka, and Telangana. Shansen Enterprises supplies this product to panel builders, OEMs, EPC contractors, and plant maintenance teams throughout India from its base in Coimbatore.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 200MO9-660?
Class gG denotes a general-purpose, full-range fuse that provides protection against both overload currents and short-circuit currents across its entire operating range. The ‘g’ indicates it is a full-range fuse (capable of breaking any current from its minimum fusing current up to its rated breaking capacity of 80 kA), while ‘G’ signifies general use for cable and equipment protection. This makes the 200MO9-660 suitable wherever a single fuse element must handle both types of fault conditions without requiring supplementary protection devices.
Is the 200MO9-660 suitable for 415 V three-phase systems used in India?
Yes. The 200MO9-660 is rated at 660/690 V AC, which provides a significant voltage margin above India’s standard 415 V line-to-line (three-phase) industrial supply. Per IEC 60269-2 guidelines, a fuse rated for a higher voltage may be used at lower voltages, so this fuse is fully suitable for 415 V systems. The higher voltage rating effectively means it is conservatively applied in standard Indian industrial panels, enhancing long-term reliability.
What is the breaking capacity of the Eaton Bussmann 200MO9-660 and why does it matter?
The 200MO9-660 has a breaking capacity of 80 kA. Breaking capacity (also called interrupt rating) is the maximum prospective short-circuit current the fuse can safely interrupt without rupturing or causing a hazard. When specifying protection for switchgear panels or distribution boards in large industrial facilities in India, it is essential to verify that the fuse’s breaking capacity equals or exceeds the prospective short-circuit current at the point of installation. An 80 kA rating is appropriate for most LV industrial applications in India.
What is the BS Size B2 and which fuse carriers are compatible?
BS Size B2 refers to the physical dimensional standard defined under BS88 Part 2, which governs the blade, tag, and body dimensions of the fuse link. Only fuse carriers, bases, and holders specifically designed for BS88 B2 size should be used with the 200MO9-660. Using an incorrectly sized carrier can compromise contact integrity and void compliance. Shansen Enterprises can assist with identifying compatible Eaton Bussmann carriers and holders — contact us via WhatsApp or email with your panel details for a recommendation.
Does the Eaton Bussmann 200MO9-660 comply with RoHS and CE requirements?
Yes. The 200MO9-660 carries CE marking and is RoHS compliant, confirming it meets European Union directives on electromagnetic compatibility and restriction of hazardous substances. For Indian projects with export obligations or multinational OEM requirements mandating RoHS and CE compliance on components, this fuse link satisfies those requirements. It is also IEC Rated under IEC 60269-2, the internationally recognised standard for low voltage fuses.
