Applications & Selection Guide
The Eaton Bussmann 25HO7-660 is the preferred choice for general-purpose overcurrent protection in low voltage switchgear assemblies, motor control centres (MCCs), and distribution boards operating at 660/690V AC. Its Class gG rating means it is designed to carry and interrupt all currents from overloads up to full short-circuit values, making it well suited for feeder and branch circuit protection where both thermal and instantaneous fault response are required without selective coordination of separate devices.
In the Indian industrial context, this fuse link is widely applied in sectors including textile manufacturing, automotive component production, pharmaceutical processing, food and beverage plants, cement and steel industries, and commercial high-rise electrical infrastructure — all concentrated in industrial hubs like Coimbatore, Chennai, Pune, Ahmedabad, and Bengaluru. The 80kA breaking capacity aligns with the fault levels encountered in medium and large industrial power distribution systems fed from dedicated transformers.
When selecting this fuse link, verify that the fuse base or holder is rated for A2 BS size and accepts a closed slot bolted tag. Confirm the system voltage does not exceed 660/690V AC and that the 25A rating is appropriate for the connected load including any applicable derating for ambient temperature. For motor loads, consider whether a Class gG general-purpose fuse or a back-up motor protection fuse better suits the application duty cycle and starting current profile.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 25HO7-660 fuse link?
Class gG denotes a general-purpose full-range fuse capable of interrupting all overcurrents from the minimum fusing current up to the rated breaking capacity of 80kA. The ‘g’ prefix indicates full-range breaking capability, and ‘G’ indicates general-purpose application for cables and conductors. This means the 25HO7-660 will respond to sustained overloads as well as high-magnitude short-circuit faults, providing comprehensive circuit protection without requiring a separate overcurrent device for the overload range.
Is the 25HO7-660 suitable for motor protection applications in Indian industrial panels?
The 25HO7-660 is a Class gG general-purpose fuse link, which provides reliable short-circuit and overload protection for cables, feeders, and general loads. For direct motor protection duties where high inrush currents during starting must be accommodated without nuisance blowing, a motor-rated fuse (Class gM or back-up type) may be more appropriate. However, the 25HO7-660 can be used upstream in motor branch circuits as feeder protection when combined with a suitable motor starter incorporating thermal overload protection. Consult Shansen Enterprises for application-specific recommendations.
What fuse holder or base is compatible with the Eaton Bussmann 25HO7-660?
The 25HO7-660 requires a BS88-compatible fuse base or holder rated for A2 BS size and designed to accept a bolted closed slot tag termination. Eaton Bussmann and other BS88-standard fuse bases in A2 configuration are compatible. Always verify that the fuse holder is rated for at least 660/690V AC and the intended current and breaking capacity to ensure a safe and compliant installation. Contact Shansen Enterprises for guidance on matching fuse bases available in India.
Does the 25HO7-660 comply with IEC standards applicable in India?
Yes. The Eaton Bussmann 25HO7-660 is manufactured to BS88 Part 2 and IEC 60269-2, which are the governing international standards for low voltage fuses used in industrial and commercial electrical installations. It carries IEC Rated certification and is CE Marked and RoHS Compliant. IEC 60269-2 is widely referenced in Indian electrical engineering specifications and is aligned with Bureau of Indian Standards (BIS) practices for low voltage switchgear and controlgear assemblies.
Can the 25HO7-660 be used in distribution boards in commercial buildings in India?
Yes, the 25HO7-660 is well suited for distribution boards in commercial buildings where the supply voltage is 660/690V AC and the circuit requires 25A overcurrent protection with high breaking capacity. Its Class gG rating provides full overload and short-circuit protection for final sub-circuits and feeder cables. The 80kA breaking capacity ensures safe fault interruption in commercial installations fed from large transformers with significant available fault current. Ensure the distribution board’s fuse ways are dimensioned for A2 BS size bolted tag fuse links.
