Overview
The Eaton Bussmann 170M6014 is a Class aR high speed square body semiconductor protection fuse rated at 1000 A and 690 V AC, offering a 200 kA interrupt rating for robust fault protection in modern power electronics systems. Part of the proven Bussmann 170M Series, this fuse is constructed in the square body 3/80 bolt-in format, delivering reliable and repeatable performance under the stringent requirements of IEC 60269-4. It is a trusted choice for design engineers and panel builders across India who specify semiconductor fuses for drives, converters, and rectifier assemblies.

Applications & Selection Guide
The Eaton Bussmann 170M6014 is the preferred choice wherever high-current semiconductor devices must be protected against destructive overcurrents. In variable frequency drives (VFDs), DC drives, active front-end converters, and rectifier bridges operating at 690 V, the 1000 A rating and 200 kA breaking capacity ensure that a bolted fault is cleared before the semiconductor junction temperature exceeds its damage threshold. The Class aR designation confirms the fuse is specifically characterised for semiconductor protection — it is not a general-purpose fuse and should not be substituted with Class gG or gR types in these circuits.
In Indian industrial settings — including automotive plants, textile mills, steel rolling mills, and process industries in and around Coimbatore, Pune, Chennai, and the broader manufacturing belt — large drive panels often specify 690 V Class aR fuses at this current level for coordinated protection of IGBT modules and thyristor stacks. The 3/80 square body bolt-in format is widely used in Indian OEM panel designs and is compatible with standard DIN and IEC mounting hardware. Engineers should verify the I²t let-through value against the semiconductor manufacturer’s withstand rating when finalising the fuse selection.
For DC common bus architectures and regenerative drive systems, the 690 V AC rating translates to an effective DC voltage capability — consult the Eaton Bussmann datasheet for confirmed DC voltage ratings before applying this fuse in DC circuits. Shansen Enterprises can assist with application engineering queries and coordinate with Eaton’s technical team for complex drive protection designs.

Frequently Asked Questions
What does the Class aR rating mean for the Eaton Bussmann 170M6014?
Class aR (current limiting, semiconductor protection range) indicates the fuse is specifically designed to protect semiconductor devices such as thyristors, IGBTs, and diodes. Unlike general-purpose Class gG fuses, Class aR fuses have a faster clearing characteristic and a tightly controlled I²t let-through value, ensuring the fuse clears the fault before the semiconductor is damaged. The 170M6014 must only be used in Class aR semiconductor protection applications and should not be used as a line fuse for cable or transformer protection without consulting the Eaton application guide.
Is the 170M6014 suitable for both AC and DC circuit protection?
The catalog-specified rated voltage is 690 V AC. Eaton Bussmann 170M Series fuses can in many cases be applied in DC circuits as well, but the allowable DC voltage rating is typically lower than the AC rating and depends on the circuit time constant. Always refer to the official Eaton Bussmann 170M6014 datasheet and application notes for confirmed DC voltage ratings before using this fuse in a DC common bus or battery system application. Shansen Enterprises can help you obtain the latest datasheet and connect with Eaton’s technical team if required.
What is the physical format of the 170M6014 and how does it mount?
The 170M6014 uses a square body 3/80 format with bolt-in connections. This is a standardised IEC form factor widely supported by Eaton Bussmann and third-party fuse holders and mounting bases. Bolt-in connections ensure a low-resistance, secure termination suitable for the high continuous current levels at which this fuse operates. Confirm the compatible fuse holder or mounting base part number with Shansen Enterprises when placing your order to ensure a complete, ready-to-install assembly.
Can the 170M6014 be used in VFD and soft starter panels built in India?
Yes. The Eaton Bussmann 170M6014 is a standard choice for semiconductor protection in VFD, soft starter, DC drive, and power converter panels assembled in India. Its IEC 60269-4 compliance and dual IEC/UL-CSA certifications make it acceptable under both IS/IEC-based Indian electrical standards and for export panels requiring UL or CSA compliance. Panel builders in Coimbatore and across India regularly use the 170M Series for drives rated at 690 V, particularly in industries such as textiles, plastics, steel, automotive, and water treatment.
Does the 170M6014 include a fuse indicator or striker pin?
No. The 170M6014 does not include a fuse indicator or striker pin. If your panel design requires blown-fuse signalling or interlock triggering, you should consider alternative 170M Series variants that include an indicator, or use an external fuse monitoring relay in conjunction with this fuse. Contact Shansen Enterprises to discuss alternative catalog numbers if a fuse indicator is required for your application.
