Applications & Selection Guide
The CEO63 is engineered for general-purpose overcurrent protection in low voltage electrical systems operating at 415 V AC — the standard three-phase voltage in India. It is ideally specified in low voltage switchgear panels (LVDB, MDB, SDB), motor control centers (MCCs), and distribution boards where reliable fault interruption and selective coordination are essential. The 63 A rating makes it well-suited for feeder circuits, sub-distribution applications, and motor branch protection where load currents are moderate and fault levels can reach up to 80 kA.
As a Class gG fuse, the CEO63 provides full-range protection — it responds to both prolonged overloads and high-magnitude short-circuit currents, unlike semiconductor or motor-type fuses that cover only a partial current range. When selecting this fuse, verify that the fuse holder or base accommodates the A4 BS size with offset tag closed slot configuration to ensure correct fit and thermal contact. Always cross-check the prospective short-circuit current at the installation point against the 80 kA breaking capacity.
Across India, the CEO63 finds application in sectors including manufacturing plants, textile mills in Coimbatore and Tiruppur, cement and chemical process industries, commercial buildings, infrastructure projects, and panel builders supplying OEM switchgear. Its IEC and BS88 dual compliance also makes it suitable for export panels destined for UK, Middle East, and Southeast Asian markets.

Frequently Asked Questions
What does the Class gG rating mean for the Eaton Bussmann CEO63?
Class gG stands for general-purpose full-range fuse — the ‘g’ prefix indicates it is a full-range fuse capable of breaking any current from the minimum fusing current up to its rated breaking capacity (80 kA for the CEO63), and ‘G’ denotes general-purpose application. This means the CEO63 protects against both sustained overloads and high-energy short-circuit faults, unlike partial-range fuses (class ‘a’) that only interrupt short-circuit currents above a minimum threshold. For most LV distribution and motor feeder circuits operating at 415 V AC in India, a Class gG fuse is the standard and correct selection.
Is the CEO63 compatible with standard BS88 fuse holders available in India?
Yes, the CEO63 is designed to the BS88 Part 2 standard with an A4 BS size and offset tag closed slot configuration. It is compatible with BS88 Part 2 fuse holders and bases that accept the A4 size with the corresponding tag format. When sourcing fuse holders, always confirm the tag type (offset tag, closed slot) matches your holder to ensure correct mechanical fit and reliable electrical contact. Shansen Enterprises can assist in identifying the correct fuse base or holder to pair with the CEO63.
What is the breaking capacity of the CEO63 and why does it matter?
The Eaton Bussmann CEO63 has a breaking capacity of 80 kA. Breaking capacity (also called interrupting rating) is the maximum prospective short-circuit current the fuse can safely interrupt without rupturing, causing an arc flash, or damaging surrounding equipment. In Indian industrial installations — especially near transformer secondaries or in high-fault-level systems — the prospective short-circuit current must be calculated and must not exceed 80 kA at the fuse installation point. Always perform a short-circuit analysis before specifying any fuse link to ensure safety and compliance.
Can the CEO63 be used for motor protection in Indian industrial panels?
The CEO63 can be used as backup short-circuit protection in motor branch circuits, but as a Class gG fuse it provides general-purpose protection rather than dedicated motor protection. For motor feeder applications, Class gM or aM (motor-duty) fuses are typically specified because they tolerate motor starting inrush currents without nuisance tripping. However, if the panel design uses a coordinated combination of overload relay and fuse, the CEO63 at 63 A may be acceptable as the short-circuit protective device — consult the motor starter coordination tables and IEC 60947-4-1 for correct pairing. Contact Shansen Enterprises for application-specific guidance.
What standards and certifications does the Eaton Bussmann CEO63 carry?
The CEO63 complies with BS88 Part 2 and IEC 60269-2 — the primary international and British standards governing low voltage fuse links. It is IEC Rated and carries CE marking, confirming conformity with applicable European directives. It is also RoHS Compliant, meaning it is free from restricted hazardous substances as per EU RoHS regulations. These certifications make it acceptable for projects governed by IEC-based specifications, BIS-aligned designs, and export panel assemblies destined for CE-marked markets.
