Description
Overview
The Eaton Bussmann 170M1559D belongs to the proven 170M Series of high speed square body semiconductor fuses, designed specifically to protect power electronic devices such as SCRs, diodes, IGBTs, and thyristors from the destructive effects of short-circuit currents. Rated at 16 A and 690 V AC with a 200 kA interrupt rating, this fuse conforms to IEC 60269-4 and is constructed to DIN 43620 DIN 000 dimensions, ensuring drop-in compatibility with standard DIN 000 fuse holders and bus-bar mounting systems. The integrated dual fuse indicator (Type D) provides both local visual and remote electrical signalling, reducing downtime during fault diagnosis in panel environments across India.

Applications & Selection Guide
The 170M1559D is the correct choice when you need reliable semiconductor protection at 16 A on 690 V AC supply systems. Its Class gR characteristic means it provides full-range protection — responding to both sustained overloads and high-energy short circuits — unlike Class aR fuses which are back-up only. This makes the 170M1559D suitable for applications where no upstream current limiting device is guaranteed to handle overload conditions independently, including individual drive output protection and rectifier arm protection in thyristor converters.
In Indian industrial contexts, this fuse is widely applied in variable frequency drives (VFDs) controlling pumps, fans, and compressors in process industries, in DC common bus drive systems used in paper mills, steel rolling mills, and material handling equipment, and in soft starter panels for large motor applications in water treatment and cement plants. The DIN 000 knife blade format is compatible with a wide range of DIN-rail and base-mounted fuse holders available in the Indian market, simplifying panel integration.
When selecting this fuse, confirm that the continuous load current does not exceed 16 A, that the system prospective short-circuit current is within the 200 kA breaking capacity, and that the power semiconductor’s I²t withstand rating is greater than the fuse’s let-through I²t at maximum fault current. For parallel semiconductor strings or higher amperage requirements, Shansen Enterprises can assist in selecting the appropriate higher-rated 170M Series variant from the complete Eaton Bussmann range stocked and available for delivery across India.

Frequently Asked Questions
What is the difference between a Class gR and a Class aR fuse, and which should I use for my VFD?
A Class gR fuse provides full-range protection, meaning it will respond to and safely interrupt both overload currents and short-circuit currents across its entire operating range. A Class aR fuse is a back-up fuse that only operates under short-circuit conditions and relies on another protective device to handle overloads. For VFD semiconductor protection where no separate overload protection device is present upstream of the semiconductor, Class gR fuses such as the 170M1559D are the correct selection. Always verify with the VFD manufacturer’s recommended fuse type before finalising your choice.
Is the 170M1559D suitable for DC common bus drive systems?
Yes. The Eaton Bussmann 170M1559D is explicitly rated for DC common bus applications as well as DC and AC drives, power converters, rectifiers, and thyristor stacks. When applying it to a DC circuit, confirm the DC voltage rating with the Eaton Bussmann datasheet for the specific DC application voltage, as DC voltage ratings for high speed fuses may differ from the stated AC voltage rating. Shansen Enterprises can provide the full datasheet and assist with DC application verification.
What does the Dual Indicator Type D mean on the 170M1559D?
The Dual Indicator Type D means the fuse is fitted with two indication mechanisms: a visual pop-up flag that becomes visible when the fuse has operated, allowing local panel inspection, and a built-in microswitch contact that provides an electrical signal output which can be wired into a control circuit or alarm system for remote blown-fuse detection. This dual functionality reduces maintenance time and improves system uptime by enabling automated fault detection without requiring manual panel inspection.
What fuse holder is compatible with the Eaton Bussmann 170M1559D?
The 170M1559D is built to DIN 43620 DIN 000 format with knife blade contacts. It is compatible with any DIN 000 format fuse holder or fuse base designed to accept knife blade contact fuses to DIN 43620 dimensions. Eaton Bussmann offers a range of matching fuse holders and bus-bar mounted bases for the 170M DIN 000 format. Contact Shansen Enterprises in Coimbatore to confirm holder compatibility and to source the complete fuse and holder assembly for your panel build.
Does the 170M1559D carry CE and RoHS certification?
Yes. The Eaton Bussmann 170M1559D is CE Marked and RoHS Compliant, and is IEC Rated per IEC 60269-4. CE marking confirms it meets applicable European health, safety, and environmental directives. RoHS compliance confirms it is manufactured without restricted hazardous substances, which is a requirement for panel builders and OEMs supplying equipment to European and many other international markets. Certificates of conformity can be requested through Shansen Enterprises at the time of order.
