Applications & Selection Guide
The CEO40 fuse link is an ideal choice for general-purpose overcurrent protection in low voltage distribution systems operating at 415V AC — the standard three-phase supply voltage across Indian industrial and commercial installations. It is widely specified in motor control centres (MCCs), main distribution boards (MDBs), sub-distribution boards, and industrial switchgear panels where reliable, predictable fault clearing is required for cables and connected equipment.
As a Class gG rated fuse, the CEO40 is suitable for protecting circuits where both overload and short-circuit protection are required in a single device. The 40A rating positions it for feeder protection of small to medium motor starters, lighting circuits, HVAC equipment, and power distribution feeders in factories, textile mills, cement plants, and automotive manufacturing facilities commonly found in and around Coimbatore and across Tamil Nadu.
When selecting fuse links for Indian industrial panels, panel builders should verify that the fuse holder or fuse base is rated for the A4 BS size and accommodates the offset tag closed slot geometry of the CEO40. For high fault-level busbars or main incomer protection with breaking demands exceeding 80 kA, consult Shansen Enterprises to evaluate higher-rated alternatives from the Eaton Bussmann range.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann CEO40 fuse link?
Class gG denotes a full-range general-purpose fuse that can interrupt all fault currents from the minimum fusing current up to the rated breaking capacity — in this case 80 kA. The lowercase ‘g’ indicates full-range breaking capability, and ‘G’ indicates the fuse is suitable for general application including cable and equipment protection. The CEO40 will clear both sustained overloads and high-level short-circuit faults within its rated parameters, making it a versatile choice for most LV distribution and motor circuit applications.
Is the CEO40 compatible with standard Indian 415V three-phase systems?
Yes. The CEO40 carries a rated voltage of 415V AC, which directly matches the standard three-phase supply voltage in India as defined under IS 732 and IEC system voltage standards. No derating is required when used in 415V AC distribution systems. It is compliant with IEC 60269-2 and BS88 Part 2, both of which are widely recognised and accepted in Indian electrical installations, industrial panels, and switchgear manufactured to IEC standards.
What is the significance of the A4 BS size and offset tag closed slot in the CEO40?
The BS size A4 refers to the physical dimensional classification defined in BS88 and IEC 60269-2 for fuse links, which determines compatibility with the correct fuse holder, fuse base, or fuse carrier. The offset tag closed slot describes the specific blade geometry at the ends of the fuse link — this ensures the CEO40 can only be installed in the correctly rated A4 fuse holder, providing a degree of anti-substitution protection and preventing accidental installation of an incorrect rating. Always verify that the fuse holder or switchgear base is rated for A4 size with offset tag geometry before installing the CEO40.
Can the CEO40 be used for motor circuit protection in MCCs?
Yes. The CEO40 is suitable for short-circuit back-up protection of motor circuits in motor control centres when used in coordination with a motor starter contactor and overload relay. As a Class gG fuse, it provides full-range protection, but for dedicated motor protection (where the fuse must withstand motor start-up inrush without operating), engineers should verify the time-current characteristic of the CEO40 against the motor starting current and duration. In some high-inrush applications, a Class aM (motor rated) fuse may be more appropriate — contact Shansen Enterprises for application-specific selection support.
What certifications and compliance markings does the CEO40 carry?
The Eaton Bussmann CEO40 is CE Marked, confirming compliance with applicable European directives including the Low Voltage Directive. It is RoHS Compliant, meaning it meets restrictions on hazardous substances required for environmentally responsible procurement. It is IEC Rated, having been tested and verified to the performance requirements of IEC 60269-2 and BS88 Part 2. These certifications make the CEO40 suitable for use in projects requiring documented product compliance, including government, infrastructure, and export-oriented manufacturing projects in India.
