Description
Overview
The Eaton Bussmann 180FEE is a high speed, double barrel, British Standard BS88 Class aR semiconductor protection fuse rated at 180 A and 690 V AC (450 V DC) with an exceptional breaking capacity of 200 kA. Engineered specifically for semiconductor protection in power electronics, it delivers the sub-cycle current limiting action required to prevent catastrophic failure of SCRs, thyristors, IGBTs, and diodes in industrial drive systems. Manufactured to BS88 Part 4 and IEC 60269-4, it carries CE marking, RoHS compliance, IEC rating, and UL recognition, making it suitable for both Indian and export-oriented panel installations.

Applications & Selection Guide
The 180FEE is the preferred choice for engineers specifying semiconductor protection in variable frequency drives (VFDs), DC common bus panels, thyristor-controlled rectifiers, and soft starter assemblies operating on 415 V or 690 V industrial supply systems in India. Its Class aR rating means it is purpose-built for semiconductor protection and must not be used as a general-purpose branch circuit fuse — it is optimised for low I²t let-through to protect devices with limited thermal withstand capability such as SCRs, diodes, and IGBTs.
In Indian industries including steel, cement, paper, chemical processing, water treatment, and textile manufacturing, high-power drive panels frequently operate with prospective fault currents that demand 200 kA breaking capacity. The 180FEE’s double barrel construction meets this requirement while maintaining the compact panel dimensions demanded by modern enclosure designs. The dual AC/DC voltage rating also makes it suitable for solar inverter and energy storage system (ESS) DC bus protection at 450 V DC.
When selecting semiconductor fuses for a drive system, always verify the fuse’s I²t (let-through energy) against the semiconductor’s rated I²t withstand. Shansen Enterprises can provide application engineering assistance to help select the correct FEE series rating for your specific drive topology, current level, and coordination requirement across Coimbatore and pan-India projects.

Frequently Asked Questions
What does Class aR mean for the Eaton Bussmann 180FEE?
Class aR designates a fuse with a partial range breaking capacity, specifically designed for semiconductor protection. Unlike Class gG general purpose fuses, a Class aR fuse operates at sub-cycle speed to limit the let-through energy (I²t) to a level that semiconductor devices — such as thyristors, SCRs, IGBTs, and diodes — can safely withstand. The 180FEE should be used only in semiconductor protection roles and not as a standalone overcurrent protection device for cables or motors.
What is the difference between the double barrel FEE design and a standard single barrel BS88 fuse?
The double barrel construction places two parallel fuse elements within a single fuse body, allowing higher current ratings and improved current limiting performance in a compact form factor. This design achieves the 200 kA breaking capacity required for high-power semiconductor protection panels while keeping the physical size manageable for dense drive cabinet layouts. Standard single barrel BS88 fuses are typically used for lower interrupt ratings and general industrial overcurrent protection.
Can the 180FEE be used for DC bus protection in solar inverters or battery energy storage systems?
Yes. The 180FEE carries a 450 V DC voltage rating, making it suitable for DC bus protection in solar inverter strings, battery energy storage systems (BESS), and other DC power electronics operating at or below 450 V DC. Always verify the system’s maximum DC voltage, fault current levels, and semiconductor I²t requirements against the fuse datasheet before installation. Contact Shansen Enterprises for application-specific guidance on PV and ESS fuse selection in India.
Is the Eaton Bussmann 180FEE certified for use in Indian industrial panels?
Yes. The 180FEE is IEC Rated to BS88 Part 4 and IEC 60269-4, which are the internationally recognised standards accepted for industrial panels in India. It also carries CE marking and RoHS compliance for export equipment, and UL Recognition for panels destined for the North American market. These certifications make the 180FEE suitable for use in domestic Indian industrial installations as well as export-oriented OEM panel builds manufactured in cities like Coimbatore, Chennai, Pune, and Ahmedabad.
What fuse holders or bases are compatible with the 180FEE double barrel body?
The 180FEE uses a double barrel BS88 body form factor. Compatible fuse holders and bus-bar mounted fuse bases from the Eaton Bussmann range designed for FEE series double barrel fuses should be specified.
