Description
Overview
The Eaton Bussmann 170M6413 is a high speed square body semiconductor protection fuse rated at 900 A and 690 V AC, engineered to safeguard IGBTs, thyristors, diodes, and other power semiconductor devices from destructive overcurrents. Part of the well-established Bussmann 170M Series, it conforms to the IEC 60269-4 standard and is housed in a compact 3BN/50 square body format with reliable bolt-in connections for secure panel integration. With a 200 kA breaking capacity and Class aR current-limiting performance, it is a trusted choice for panel builders and OEMs across India deploying high-power drive and converter systems.
Key Features
- 900 A Amperage Rating — handles high continuous current loads typical in large drive panels and power conversion systems

- 200 kA Interrupt Rating — provides extremely high fault interruption capacity for protection in high energy bus systems
- Class aR Current-Limiting Performance — fast-acting semiconductor fuse class that limits let-through energy to protect expensive semiconductor devices
- 3BN/50 Square Body Format — industry-standard footprint enabling straightforward replacement and panel standardisation
- Bolt-In Connections — ensures low-resistance, vibration-resistant termination in demanding industrial environments
- IEC 60269-4 Compliant — meets international standard for semiconductor fuse performance and testing
- IEC Rated, UL/CSA Listed — dual certification supports use in Indian plants as well as export machinery

Applications & Selection Guide
The Eaton Bussmann 170M6413 is specifically selected when engineers need to protect high-power semiconductor devices — including IGBTs, SCRs, thyristors, and power diodes — in industrial drive panels and converter cabinets operating at 690 V AC. Its Class aR rating means it is optimised for semiconductor protection duty: it reacts fast enough to limit the let-through I²t energy before the semiconductor junction fails, which is a critical requirement that standard gG or gR fuses cannot reliably meet. The 900 A rating makes it the right choice for large VFDs, multi-axis servo drives, and DC bus architectures where bus currents are high and fault energy is substantial.
In Indian industrial applications, this fuse is widely used in sectors such as steel rolling mills, cement plants, paper mills, water treatment, and automotive manufacturing — wherever large variable frequency drives, soft starters, or thyristor-based DC drives are employed. The 200 kA interrupt rating provides an additional safety margin in facilities with high available short-circuit current at the point of installation, such as those fed from large transformers or close to MV/LV substations.
When selecting the 170M6413, verify that your fuse holder or fuse base is rated for the 3BN/50 square body format with bolt-in termination. Ensure the system’s prospective short-circuit current does not exceed 200 kA, and confirm the continuous operating current does not exceed 900 A under the installation’s ambient temperature and derating conditions. Refer to Eaton Bussmann application notes or contact Shansen Enterprises for selection assistance.

Frequently Asked Questions
What is the difference between a Class aR fuse and a Class gR fuse for semiconductor protection?
A Class aR fuse, like the Eaton Bussmann 170M6413, is a partial-range current-limiting fuse designed exclusively for semiconductor protection. It operates only above a defined minimum breaking current and must be coordinated with a backup fuse or circuit breaker to handle lower-level overloads. A Class gR fuse is a full-range fuse that can interrupt currents from overload through to short-circuit, providing both overload and short-circuit protection in a single device. For critical semiconductor applications such as VFDs and thyristor stacks, Class aR is the standard choice because its extremely low I²t let-through at high fault currents provides the best protection for semiconductor junctions.
Is the Eaton Bussmann 170M6413 suitable for DC bus applications in VFD panels?
Yes. The 170M6413 is listed by Eaton for use in DC common bus and DC drive applications. However, when applying any AC-rated fuse on a DC circuit, you must verify the DC voltage rating with the manufacturer’s published DC derating data, as DC interruption is more demanding than AC. Shansen Enterprises can assist you in confirming the correct DC application parameters for this fuse — contact us via WhatsApp or email with your DC bus voltage and fault current details.
What fuse holder or fuse base is compatible with the Eaton Bussmann 170M6413?
The 170M6413 uses the standard 3BN/50 square body format with bolt-in connections. It is compatible with Eaton Bussmann fuse holders and fuse bases designed for the 170M Series square body format at this body size. Always confirm the holder’s current and voltage rating meets or exceeds 900 A and 690 V. Contact Shansen Enterprises for a matched fuse holder recommendation to ensure a complete, certified assembly.
Does the Eaton Bussmann 170M6413 have a fuse indicator or striker pin?
No, the 170M6413 is supplied without a fuse indicator or striker pin. If your panel design requires blown-fuse signalling for alarming or interlock purposes, you will need to implement blown-fuse detection at the system level — for example, via voltage sensing relays or an external monitoring module. Eaton Bussmann does offer indicator accessories for certain 170M Series variants; contact Shansen Enterprises to check availability of indicator-equipped alternatives if this is a requirement.
What certifications does the Eaton Bussmann 170M6413 carry and are they valid for installations in India?
The 170M6413 is IEC Rated, UL/CSA Listed, CE Marked, and RoHS Compliant. The IEC 60269-4 rating is the relevant international standard recognised by Indian electrical inspectorates and OEM customers operating to IS/IEC standards in India. UL and CSA listings additionally support use in export equipment destined for North American markets. The CE Mark confirms compliance with European directives, which is relevant for machinery exported to Europe. For specific approval or documentation requirements for your project in India, please contact Shansen Enterprises.
