Applications & Selection Guide
The 100FEE is purpose-built for semiconductor protection in power electronic assemblies where standard gG or gL fuses operate too slowly to prevent device damage. In variable frequency drives (VFDs), DC drives, soft starters, and rectifier bridges, a Class aR fuse like the 100FEE limits the let-through energy (I²t) to a level that keeps thyristors, SCRs, and diodes within their rated surge limits, preventing costly downtime and component replacement. The double barrel BS88 form factor integrates directly into standard BS88 fuse holders and DIN-rail mounted fuse bases commonly used in Indian switchgear panels.
At 690V AC, the 100FEE covers the full range of three-phase 415V and 690V industrial installations in India, while the 450V DC rating makes it directly applicable to DC bus protection in common bus drive systems and battery-backed UPS rectifiers. The 200 kA breaking capacity exceeds the prospective fault levels found in most medium and large industrial distribution boards across manufacturing plants, infrastructure projects, and process industries in Tamil Nadu and throughout India.
Industries in Coimbatore and across India that regularly specify the Bussmann FEE series include textile machinery manufacturers, pump and motor drive OEMs, renewable energy converter builders, CNC machine tool integrators, and panel builders serving steel, cement, and chemical process plants. When selecting, confirm the existing fuse holder is rated for the double barrel form factor and that the system I²t withstand of the semiconductor device exceeds the fuse’s published pre-arcing I²t at the expected fault current level.

Frequently Asked Questions
What is the difference between a Class aR fuse and a Class gG fuse for semiconductor protection?
A Class gG fuse is a general purpose fuse designed to carry full load current and clear faults from overload to short circuit, but its relatively slow operating characteristic allows high let-through energy during fast overcurrents, which can destroy semiconductors. A Class aR fuse like the 100FEE is a current-limiting, fast-acting fuse specifically designed for semiconductor protection — it operates in the sub-cycle range during high fault currents, limiting the I²t energy delivered to the semiconductor device to a level below its rated surge withstand. Class aR fuses do not provide overload protection on their own and are typically applied in combination with a contactor or upstream breaker for complete circuit protection.
Can the Eaton Bussmann 100FEE be used for DC bus protection in a common bus VFD system?
Yes. The 100FEE carries a 450V DC voltage rating, making it suitable for DC bus protection in common bus variable frequency drive architectures, DC-fed converter systems, and rectifier output circuits operating at or below 450V DC. Always verify that the system DC voltage does not exceed 450V under any operating or regenerative braking condition. For DC applications above 450V, consult Eaton’s FEE series datasheets or contact Shansen Enterprises for an alternative catalog number with a higher DC voltage rating.
What fuse holder or fuse base is compatible with the 100FEE double barrel fuse?
The 100FEE uses the BS88 double barrel form factor. It requires a fuse holder or fuse base specifically designed for the BS88 double barrel type, rated for at least 690V AC and 100A continuous current. Eaton Bussmann offers compatible fuse holders within its BS88 accessory range. Panel builders in India should confirm the holder’s current and voltage ratings, contact material, and terminal connection type before installation. Shansen Enterprises can advise on the correct holder selection for your specific panel layout and busbar arrangement.
Does the 100FEE carry UL recognition, and is it suitable for export equipment?
Yes. The Eaton Bussmann 100FEE is UL Recognized in addition to being IEC Rated and CE Marked. UL recognition is particularly relevant for Indian OEMs building equipment for the North American market or for multinational end-users specifying UL-listed components. The CE marking and RoHS compliance support equipment exported to European Union markets. Always verify the applicable UL file number and category code on the Eaton product documentation to ensure it matches your equipment certification requirements.
What breaking capacity does the 100FEE provide, and is it sufficient for industrial installations in India?
The 100FEE has a breaking capacity of 200 kA, which is among the highest available for fuses in this current rating class. Most industrial low voltage distribution systems in India, including large manufacturing plants, data centres, and infrastructure projects, have prospective short-circuit currents well below 200 kA at the point of fuse installation. This high interrupt rating provides a significant safety margin and ensures the fuse can safely clear the most severe fault conditions encountered in Indian industrial and commercial power systems.
