Applications & Selection Guide
The Eaton Bussmann 100L14-660 is the right choice for panel builders and electrical engineers requiring reliable overcurrent protection in low voltage distribution systems operating at up to 660/690V AC. The Class gG rating makes it suitable for protecting cables, busbars, and general-purpose loads where full-range current protection is required — from overloads through to short circuit conditions.
This fuse link is widely used in motor control centres (MCCs), power distribution boards, low voltage switchgear panels, and industrial feeder circuits. The 80 kA breaking capacity meets the fault current levels commonly encountered in high-power industrial installations such as those found in the textile mills, automotive manufacturing plants, engineering industries, and process industries concentrated in Coimbatore and across Tamil Nadu.
When selecting this fuse for a project, confirm that the panel fuse carrier or fuse base is rated for BS Size A4 and accommodates a bolted-type fuse link with a closed slot tag. For semiconductor or motor starting applications requiring current-limiting or time-delay characteristics, alternative Bussmann series fuses should be considered. Shansen Enterprises can assist with cross-referencing and application support for projects across India.

Frequently Asked Questions
What does Class gG mean for the Eaton Bussmann 100L14-660 fuse link?
Class gG stands for General Purpose, Full-Range Breaking Capacity as defined under IEC 60269 and BS88 standards. A gG fuse provides overcurrent protection across the full range of fault currents — from sustained overloads to high short-circuit currents. The 100L14-660 will operate reliably at both low overload multiples and at fault currents up to 80 kA, making it suitable for protecting cables and general electrical equipment in switchgear panels and distribution boards.
What is the BS Size A4 and why does it matter when replacing this fuse?
BS Size A4 is a standardised physical dimension classification under BS88 Part 2 for bolted-type fuse links. The fuse size determines the physical dimensions and terminal configuration of the fuse, which must match the fuse carrier or fuse base installed in your panel. When replacing or specifying the 100L14-660, confirm that your fuse carrier or base is designed for A4 size bolted fuse links. Using an incorrect size may result in improper contact or safety hazards.
Can the Eaton Bussmann 100L14-660 be used on 690V AC systems in India?
Yes. The 100L14-660 is rated for 660/690V AC, making it suitable for use on both 660V and 690V AC systems. While the standard distribution voltage in India is 415V AC (three-phase), 690V systems are used in certain industrial applications including high-efficiency motor drives and specialised process equipment. This fuse link’s voltage rating provides adequate margin for these applications, and its IEC 60269-2 compliance ensures it meets the performance requirements for both voltage levels.
What is the breaking capacity of the 100L14-660 and is it sufficient for Indian industrial panels?
The Eaton Bussmann 100L14-660 has a breaking capacity of 80 kA, which means it can safely interrupt fault currents up to 80,000 amperes without rupture or hazard. For most low voltage industrial panels in India — including MCCs, PCC panels, and distribution boards fed from medium voltage transformers — the prospective short circuit current rarely exceeds 50 kA at the fuse location. An 80 kA breaking capacity provides a substantial safety margin and satisfies the requirements of most industrial panel builders and EPC contractors across India.
Is the Eaton Bussmann 100L14-660 RoHS and CE compliant?
Yes. The 100L14-660 carries both CE Marking and RoHS compliance. CE Marking confirms that the product meets applicable European Union safety, health, and environmental protection requirements. RoHS compliance confirms that the fuse does not contain restricted hazardous substances such as lead, mercury, or cadmium above permitted thresholds. These certifications are increasingly required for projects involving equipment export to Europe and for customers with corporate environmental compliance mandates.
