Applications & Selection Guide
The Eaton Bussmann 500R11-660 is ideal for general-purpose overcurrent protection in low voltage electrical infrastructure operating at 660 or 690 V AC. Its Class gG rating means it is designed to carry and interrupt currents from the minimum fusing current up to the maximum breaking capacity of 80 kA, making it suitable for protection of cables, busbars, and distribution circuits rather than motor-specific or semiconductor applications where gM or aR classes would apply.
This fuse link is well suited for use in main and sub-main distribution boards, incoming and outgoing feeder circuits in LV switchgear panels, and motor control center bus protection. The 500 A rating positions it for high-current distribution feeders in medium to large industrial facilities where fault energies are significant and reliable interruption is critical.
In the Indian industrial context, the 500R11-660 finds application across sectors such as automotive manufacturing, textile mills, steel processing, cement plants, pharmaceutical production facilities, and large commercial complexes in cities like Coimbatore, Chennai, Pune, Mumbai, and Ahmedabad — wherever robust, standards-compliant LV protection is specified by electrical consultants and panel builders.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 500R11-660?
Class gG denotes a general-purpose fuse link with full-range breaking capacity. This means the 500R11-660 is capable of interrupting all overcurrents from its minimum fusing current right up to its rated breaking capacity of 80 kA. It provides protection against both sustained overloads and high-level short-circuit faults, making it suitable for the protection of cables and general distribution circuits in low voltage systems.
What is the difference between BS88 Part 2 and IEC 60269-2 for this fuse link?
BS88 Part 2 is the British Standard for low voltage fuse links with BS-standard fittings, while IEC 60269-2 is the corresponding international standard published by the International Electrotechnical Commission. For the 500R11-660, compliance with both means the product meets harmonized performance requirements for time-current characteristics, breaking capacity, and dimensional form factors recognized across the UK, Europe, and IEC-adopting countries including India. The two standards are technically aligned, so a fuse certified to one is generally recognized under the other.
Can the 500R11-660 be used in motor circuit protection applications?
The 500R11-660 carries a Class gG rating, which is designed for general-purpose full-range protection of cables, busbars, and distribution circuits. For dedicated motor circuit protection — particularly where high starting currents must be tolerated without nuisance blowing — Class gM or motor-rated fuses (aM type) are typically recommended. However, the 500R11-660 can be used at the incoming supply level of a motor control center to protect the upstream distribution network, with motor-specific fuses applied at individual motor branch circuits.
What fuse base or holder is compatible with the 500R11-660?
The 500R11-660 is a BS88 C2 size, bolted-type fuse link with a double-slot tag. It requires a compatible BS88 C2 rated fuse base or carrier that accepts bolted double-slot tag connections and is rated for at least 500 A and 660/690 V AC service. Always verify the mechanical and electrical ratings of the fuse base before installation, and consult the Eaton Bussmann product selector or contact Shansen Enterprises for specific base and holder recommendations.
Is the Eaton Bussmann 500R11-660 RoHS compliant and CE marked?
Yes. The 500R11-660 is both CE marked and RoHS compliant. CE marking confirms the product meets relevant European Union directives for safety and electromagnetic compatibility. RoHS compliance ensures the fuse link restricts the use of hazardous substances such as lead, mercury, and cadmium, aligning with environmental regulations applicable to electrical and electronic equipment. These compliances are relevant for projects requiring documentation for regulatory submissions or export to European markets.
