Applications & Selection Guide
The 400P11-660 is engineered for general-purpose overcurrent protection in low voltage power systems operating at up to 660/690 V AC. It is the preferred choice wherever cable and equipment protection against overloads and short circuits must be handled by a single fuse element — typical in main distribution boards, sub-main feeders, and busbar protection duties in industrial plants and commercial complexes.
The Class gG designation (general purpose, full range) means this fuse link will operate across the complete range of overcurrents from sustained overloads through to high prospective fault currents up to 80 kA. At 400 A it is well suited to protecting large motor feeders, transformer secondaries, and incomer protection in motor control centres (MCCs), particularly in heavy industries such as cement, steel, textiles, automotive manufacturing, and process plants common across Tamil Nadu, Maharashtra, Gujarat, and other industrial belts of India.
When selecting this fuse link, verify that your fuse base or fuse carrier accepts a BS88 C1 bolted double-slot tag configuration and is rated for 660/690 V AC service. Always cross-check the fuse holder prospective short-circuit current rating against the installation’s available fault level — the 80 kA breaking capacity of the 400P11-660 comfortably covers most LV distribution scenarios.

Frequently Asked Questions
What does the Class gG rating mean for the Eaton Bussmann 400P11-660?
Class gG stands for general purpose, full-range fuse. The lowercase ‘g’ indicates the fuse can operate across the full range of overcurrents — from small sustained overloads up to very high short-circuit currents. The uppercase ‘G’ denotes general application, meaning it is primarily used for cable and equipment protection rather than semiconductor or motor-specific duties. For the 400P11-660, this means it will reliably clear both an overloaded feeder and a bolted fault up to 80 kA at 660/690 V AC.
What is the difference between a BS88 bolted fuse link and a BS88 blade contact fuse link?
A bolted fuse link, such as the 400P11-660 with its C1 double-slot tag body, is mechanically fastened into the fuse base using bolts or screws, providing a very secure, vibration-resistant contact. This design is preferred in high-current, high-fault-energy applications where contact integrity under fault conditions is critical. Blade contact (knife blade) fuse links slide or clip into their carriers and are generally used in lower current ranges or where quick fuse replacement without tools is prioritised. At 400 A and 80 kA, the bolted design of the 400P11-660 is the appropriate choice for robust industrial installations.
Can the 400P11-660 be used to protect motors directly?
The 400P11-660 carries a Class gG rating, which is a general-purpose classification and is not optimised for motor branch circuit protection on its own. For direct motor protection, Class aM (motor duty) fuse links — which do not operate on overloads and rely on separate overload relays — are typically used in combination with contactors. However, a gG fuse of suitable rating is frequently used as the upstream short-circuit protection element in a motor feeder, coordinated downstream with an MPCB or contactor-overload relay combination. Consult Shansen Enterprises for a full motor circuit coordination study if required.
Is the Eaton Bussmann 400P11-660 compliant with Indian electrical installation standards?
Yes. The 400P11-660 complies with BS88 Part 2 and IEC 60269-2, both of which are internationally recognised low voltage fuse standards referenced in Indian electrical engineering practice and accepted by major project consultants, EPCs, and inspection authorities across India. It is CE Marked and RoHS Compliant and carries IEC certification, satisfying the requirements of most industrial, commercial, and infrastructure projects in India. If your project requires specific Bureau of Indian Standards (BIS) certification, please contact Shansen Enterprises to confirm current compliance status.
What fuse base or carrier is compatible with the 400P11-660 bolted fuse link?
The 400P11-660 requires a BS88 C1-rated fuse base or fuse carrier designed for bolted (double-slot tag) fuse links at 400 A and 660/690 V AC. Eaton Bussmann manufactures a range of compatible fuse bases and DIN-rail mountable carriers within the BS88 product family. It is essential to verify that the chosen base is rated for the same voltage and that the busbar or terminal connections are rated for the full 400 A continuous current. Shansen Enterprises can assist with complete fuse and holder selection for your panel design.
