Description
Overview
The Eaton Bussmann 170M6011 is a 700 A rated, 690 V AC high speed square body semiconductor fuse belonging to Eaton’s industry-proven 170M Series. Engineered to IEC 60269-4 with a 200 kA breaking capacity, this Class aR fuse provides precise, fast-acting protection for IGBTs, SCRs, diodes, and other power semiconductors in high-energy industrial environments. Its 3/80 format bolt-in square body construction simplifies panel assembly and replacement in converter cabinets, variable frequency drives, and DC bus systems.
Key Features

Applications & Selection Guide
The Eaton Bussmann 170M6011 is the preferred choice for engineers specifying semiconductor fuse protection in variable frequency drives (VFDs), soft starters, DC common bus panels, controlled rectifiers, power converters, and thyristor stacks rated up to 700 A at 690 V AC. Its Class aR characteristic means it is strictly intended for back-up semiconductor protection — it will coordinate with upstream circuit breakers or gG fuses to clear faults before semiconductor junctions are damaged, but it is not a general-purpose fuse and should not be used as the sole overcurrent protective device for cables or transformers.
In Indian industrial applications, the 170M6011 is widely used in cement plants, steel rolling mills, paper mills, water treatment facilities, and large HVAC installations in Coimbatore, Chennai, Pune, Ahmedabad, and across Tamil Nadu and Maharashtra, wherever high-power drive systems require reliable semiconductor-level protection. The 690 V rating aligns directly with the most common medium-power VFD supply voltage in Indian factories.
When selecting this fuse, verify that the drive or converter manufacturer’s I²t let-through value is within the fuse’s published I²t characteristics. Always replace with the identical catalog number 170M6011 to maintain the coordination study. For applications requiring a fuse indicator for remote monitoring or visual blown-fuse detection, consider the indicator-equipped variant in the 170M Series.

Frequently Asked Questions
What does Class aR mean for the Eaton Bussmann 170M6011?
Class aR (accompaniment Range) is an IEC fuse classification specifically defined for semiconductor protection. Unlike Class gG general-purpose fuses that must protect both overloads and short circuits, a Class aR fuse is optimised to operate only at high fault currents — it clears faults so rapidly that the energy let-through (I²t) stays below the damage threshold of IGBTs, SCRs, and diodes. The 170M6011 must always be used alongside an upstream general-purpose protective device that handles the overload range.
Can the Eaton Bussmann 170M6011 be used on a DC common bus system?
Yes. The 170M Series is explicitly rated and applied in DC common bus drive systems. However, the DC voltage rating must be confirmed from the Eaton Bussmann datasheet for the 170M6011 before installation. DC applications typically derate the voltage compared to the AC rating. Please contact Shansen Enterprises with your DC bus voltage and short-circuit current level and our team will confirm suitability and provide the full derating data.
What is the difference between the 170M6011 and other fuses in the 170M Series?
The Eaton Bussmann 170M Series covers a wide range of amperage ratings, voltage ratings, body sizes, and indicator options — all sharing the same high-speed Class aR semiconductor protection characteristic. The 170M6011 is specifically the 700 A, 690 V AC, 3/80 square body, no-indicator variant. Other catalog numbers in the series differ in current rating, voltage rating, physical size format, or the presence of a fuse indicator. Always use the exact catalog number specified in the drive or converter manufacturer’s documentation to maintain I²t coordination.
Is the Eaton Bussmann 170M6011 approved for use in India?
Yes. The 170M6011 is CE marked and complies with IEC 60269-4, which is the internationally recognised standard adopted in Indian industrial electrical installations. It also carries UL and CSA listings for equipment destined for North American markets. The product meets RoHS requirements for hazardous substance restrictions. Shansen Enterprises supplies IEC-certified Eaton Bussmann fuses to panel builders, OEMs, and EPC contractors throughout India from our base in Coimbatore, Tamil Nadu.
What fuse holder is compatible with the Eaton Bussmann 170M6011?
The 170M6011 uses a 3/80 square body format with bolt-in connections. It is compatible with Eaton Bussmann fuse holders and fuse blocks designed for the 170M Series 3/80 format at 700 A. The specific holder catalog number depends on your bus bar arrangement, panel layout, and whether you require DIN rail mounting or direct bus bar mounting. Contact Shansen Enterprises with your panel drawing or drive specification and we will recommend the correct holder accessory.
