Applications & Selection Guide
The 560R11-660 is purpose-built for general purpose circuit protection in low voltage power distribution networks operating at up to 660/690V AC. It is the preferred choice for main incomer protection, busway tap-offs, and large feeder circuits in switchgear panels and motor control centres (MCCs) where high fault current levels demand a fuse link with substantial breaking capacity. Its 80 kA rating makes it appropriate for use in facilities supplied directly from medium voltage transformers where prospective fault levels are elevated.
As a Class gG fuse, the 560R11-660 offers full-range overcurrent protection — it operates across the complete spectrum from sustained overloads to bolted three-phase short circuits. This makes it particularly well-suited to applications where both cable and equipment protection are required without the need for separate back-up fusing. The bolted double-slot tag configuration ensures a low-impedance, mechanically stable connection that withstands the electromagnetic stresses associated with high fault current interruption.
Across India, this fuse link finds application in industries such as steel and metals processing, cement manufacturing, chemical and petrochemical plants, large commercial complexes, data centres, and infrastructure projects. Panel builders and electrical contractors in Coimbatore and across Tamil Nadu, Maharashtra, Gujarat, and other industrial states regularly specify Bussmann R11 series fuse links for compliance-critical LV distribution projects. Shansen Enterprises stocks and supplies this product with short lead times for both individual project requirements and bulk panel builder orders.

Frequently Asked Questions
What does the Class gG rating mean for the Eaton Bussmann 560R11-660?
Class gG designates a general purpose, full-range fuse link under IEC 60269 / BS88 standards. The ‘g’ indicates a general purpose fuse capable of breaking any current causing the fuse to operate, from the minimum fusing current up to the rated breaking capacity (80 kA for this product). The second ‘G’ indicates it is suitable for general use — protecting cables and equipment against both sustained overloads and short-circuit faults. This makes the 560R11-660 suitable for main distribution circuits without requiring a separate back-up fuse.
What is the difference between the bolted tag type and a knife-blade fuse link?
Bolted tag fuse links, such as the 560R11-660, use flat tags with mounting holes that are mechanically secured to busbars or fuse bases using bolts, providing a low-resistance, high-integrity connection capable of handling very high currents reliably over time. Knife-blade (or blade contact) fuse links use a sliding blade-and-clip contact system. Bolted tag designs are generally preferred for higher current ratings and applications where vibration resistance and connection stability are priorities, such as main distribution boards and switchgear busbars.
Is the 560R11-660 suitable for motor circuit protection in Indian industrial installations?
The 560R11-660 is a Class gG general purpose fuse link, which is well-suited for feeder and incomer protection in motor control centres (MCCs). However, for direct motor branch circuit protection — particularly where high starting currents demand a fuse that does not operate during motor start — a Class gM or semiconductor-type fuse may be more appropriate for the motor branch itself. The 560R11-660 is best applied upstream as a main feeder or distribution fuse within the MCC, coordinating with downstream motor protection devices. Shansen Enterprises can assist with protection coordination advice for your specific application.
Can the Eaton Bussmann 560R11-660 be used at 690V AC systems in India?
Yes. The 560R11-660 carries a dual voltage rating of 660/690V AC, making it fully suitable for use in 690V AC industrial distribution systems. While 415V AC (400V system) is the most common industrial voltage in India, 690V AC systems are encountered in large industrial drives, offshore installations, and certain export-specification switchgear. This fuse link is rated and tested to perform safely at both voltage levels in accordance with BS88 Part 2 and IEC 60269-2.
What BS size and tag type should the replacement fuse holder support for the 560R11-660?
The 560R11-660 is a BS Size C2 fuse link with a Double Slot bolted tag connection. Any replacement fuse holder, fuse base, or fuse switch disconnector must be rated for BS88 Size C2, Double Slot bolted tag fuse links, and must carry a current and voltage rating equal to or greater than 560A and 660/690V AC. Always verify the fuse gear manufacturer’s compatibility data before installation, or contact Shansen Enterprises for guidance on selecting the correct fuse base or holder.
