Applications & Selection Guide
The CD80 fuse link is designed for general-purpose overcurrent protection wherever a reliable, high breaking-capacity device is required in 415 V AC LV systems. Typical installation points include incoming and outgoing feeder ways in distribution boards, bus-bar sections of low voltage switchgear, and motor control centre incomer circuits where prospective fault currents can reach or exceed 80 kA. The bolted-tag format suits high-current assemblies where a secure, vibration-resistant connection is preferred over clip-in carriers.
Class gG fuses are specified when full-range protection — covering both sustained overloads and dead short-circuits — is required without coordinating a separate back-up fuse. When selecting the CD80, confirm that the prospective short-circuit current at the installation point does not exceed 80 kA and that the upstream supply voltage does not exceed 415 V AC. For motor circuits, verify that the fuse rating is compatible with the motor’s starting current profile; where high inrush is a concern, a gM or aM class device may be more appropriate for the motor branch while the CD80 continues to protect the feeder.
Across India, BS88 gG fuse links of this type are widely used in textile mill switchrooms in Coimbatore, automotive ancillary plant MCC rooms in Pune and Chennai, pharmaceutical manufacturing distribution boards in Ahmedabad and Hyderabad, and commercial building LV panels in metros. The IEC 60269-2 compliance makes the CD80 acceptable under BIS-aligned specifications and for projects following international electrical standards.

Frequently Asked Questions
What does the Class gG designation mean for the Eaton Bussmann CD80 fuse link?
Class gG (general purpose, full-range breaking capacity) indicates that the CD80 is rated to interrupt all overcurrents from the minimum fusing current — typically around 1.6 times the rated current — up to its full 80 kA breaking capacity. This means a single fuse link handles both sustained overloads and high-level short-circuit faults, making it suitable for feeder and distribution circuits where comprehensive protection from one device is required. It is distinct from aM (motor) class fuses, which are designed only for short-circuit back-up protection in motor circuits.
Is the CD80 suitable for use in standard 415 V three-phase distribution systems in India?
Yes. The CD80 carries a rated voltage of 415 V AC, which directly matches the nominal three-phase LV supply voltage used throughout India (415 V line-to-line, 50 Hz). It is IEC 60269-2 rated and CE marked, aligning with the electrical standards referenced in Indian industrial and commercial electrical installations. Always verify that the actual prospective short-circuit current at your installation point does not exceed the 80 kA breaking capacity stated for this fuse.
What is the breaking capacity of the CD80 and why does it matter?
The CD80 has a breaking capacity of 80 kA. This is the maximum prospective fault current the fuse can safely interrupt without rupturing its body, causing an arc flash, or failing to clear the fault. In practice, installations close to large distribution transformers or with low source impedance can have prospective fault currents in the range of 25–80 kA; selecting a fuse with a breaking capacity equal to or greater than the prospective fault current at that point is a fundamental safety and compliance requirement. If your system’s prospective short-circuit current exceeds 80 kA, a higher-rated device must be specified.
What is the BS Size B1 and how does it affect fuse holder selection?
BS Size B1 is a standardised physical dimension defined in BS88 Part 2 for low voltage fuse links. The B1 designation governs the body length, diameter, and tag geometry of the fuse, ensuring that only correctly rated fuse links can be fitted into a B1-rated fuse base or holder — a key safety interlock that prevents under-rated fuses from being installed in higher-current positions. When selecting a fuse holder or base for the CD80, specify a unit rated for BS88 B1 centre-tag bolted-type fuse links. Using the correct BS size is mandatory for both safety compliance and correct mechanical assembly.
Can the CD80 be used for motor circuit protection in motor control centres?
The CD80 Class gG fuse link can be used on the incoming feeder or incomer section of a motor control centre operating at 415 V AC where full-range protection of the distribution circuit is required. For the individual motor branch circuit, however, gG fuses must be sized carefully against the motor’s full-load current and starting inrush — oversizing to pass starting current can reduce overload protection effectiveness. In many motor branch-circuit designs, an aM class fuse is preferred for short-circuit back-up with a thermal overload relay handling overload protection. Consult Shansen Enterprises’ technical team for motor circuit coordination advice specific to your application.
