Applications & Selection Guide
The Eaton Bussmann 450R11-660 is specifically designed for general-purpose overcurrent and short-circuit protection across a wide range of industrial electrical installations. Its Class gG rating makes it ideal for protecting cables, busbars, and distribution circuits where full-range protection from overload through to short-circuit fault conditions is required. The 450 A rating and 660/690 V AC suitability make it a direct fit for heavy industrial feeders and incoming protection within low voltage switchgear assemblies.
This fuse link is commonly specified in motor control centres (MCCs), main distribution boards (MDBs), and sub-distribution panels operating at 415 V to 690 V AC in Indian industrial environments. Its 80 kA breaking capacity ensures it can safely interrupt fault currents even in high-capacity transformer-fed systems typical of large manufacturing plants, process industries, and commercial complexes.
In the Indian context, the 450R11-660 is well suited for industries such as automotive manufacturing, textile mills, cement plants, steel processing, chemical and pharmaceutical facilities, and large commercial infrastructure projects in Tamil Nadu and across India. Panel builders and OEMs in Coimbatore and other industrial centres rely on this BS88 Series fuse link for its dimensional consistency, proven reliability, and straightforward panel integration using the BS Size C2 form factor.

Frequently Asked Questions
What does the Class gG rating mean for the Eaton Bussmann 450R11-660?
Class gG stands for general-purpose, full-range fuse protection. This means the 450R11-660 is capable of interrupting all fault currents from the minimum fusing current (overload range) up to the maximum rated breaking capacity of 80 kA. It is designed to protect cables and distribution circuits — not specifically for motor starting applications, for which Class aM fuses would be more appropriate. The gG classification is defined under IEC 60269-2 and BS88 Part 2 and is widely accepted in Indian and international low voltage switchgear standards.
Is the Eaton Bussmann 450R11-660 suitable for use on Indian 415 V industrial supplies?
Yes, the 450R11-660 is rated for 660/690 V AC, which means it is fully compatible with Indian standard 415 V (line-to-line) three-phase industrial supply systems. A fuse rated for a higher voltage is always safe to use at a lower operating voltage, making this fuse link suitable for the full range of Indian LV distribution voltages from 415 V up to 690 V AC.
What is the BS Size C2 designation and which fuse holders does it fit?
BS Size C2 is a standardised dimensional classification defined in BS88 and IEC 60269-2 for fuse links used in bolted-type fuse bases and holders. The C2 size dictates the physical length, blade width, and mounting hole spacing of the fuse link. When sourcing a replacement or specifying a new installation, you must ensure the fuse holder or fuse base in your switchgear or distribution board is rated for BS Size C2 to achieve correct mechanical fit and electrical contact. Please contact Shansen Enterprises to confirm compatible holder options.
What is the difference between a Centre Tag and End Tag fuse link in the BS88 series?
In BS88 fuse links, the tag type refers to the position of the label or identification tag on the fuse body. A Centre Tag fuse has its identification label located at the centre of the fuse barrel, while an End Tag fuse has the label at one end. The tag type is primarily a mechanical and handling identification feature and does not affect the electrical performance of the fuse. However, it is important to match the tag type specified in your panel design or original equipment specification to ensure correct fitment and labelling compliance.
Can the 450R11-660 be used for motor circuit protection in a motor control centre?
The 450R11-660 carries a Class gG rating, which provides general-purpose full-range protection suitable for feeder and distribution circuit protection within a motor control centre (MCC). For direct motor branch circuit protection — particularly where high motor starting currents must be tolerated without fuse operation — a Class aM (motor duty) fuse would typically be specified for the branch circuit, while the gG fuse such as the 450R11-660 would be used at the incoming or feeder level. Always consult your system design engineer or contact Shansen Enterprises for application-specific guidance.
