Description
Overview
The Eaton Bussmann 170M1569D belongs to the proven 170M Series of high speed square body semiconductor fuses, purpose-built to protect sensitive power electronic components from destructive fault currents. Rated at 160A and 690V AC with a 200 kA interrupt rating, this fuse conforms to DIN 43620 DIN 000 format with knife blade contacts, making it directly compatible with standard DIN fuse bases used widely in industrial drive and converter panels. Its dual fuse indicator (Type D) allows both local visual inspection and remote trip signalling, supporting fast maintenance response in production environments.

Applications & Selection Guide
The 170M1569D is the correct choice when you need dependable semiconductor protection at 160A in 690V AC industrial systems. Its Class aR rating means it is optimised specifically for semiconductor fuse duty — acting faster than general-purpose gG or gR fuses to interrupt fault current before it can destroy IGBTs, thyristors, diodes, or MOSFETs inside drives and converters. It is particularly well suited to DC common bus architectures, where multiple drives share a common DC link and a single fuse failure must be contained without cascading damage.
In India, this fuse series is widely used in industries such as steel and metals processing, paper and pulp, cement, water treatment, textile mills, and automotive manufacturing — wherever variable frequency drives, soft starters, or large rectifier banks are installed. The DIN 000 knife blade format ensures it drops into existing panel designs without modification, reducing downtime during maintenance or replacement.
When selecting this fuse, verify that your fuse holder or fuse base is rated for DIN 43620 DIN 000 format and knife blade contacts. Ensure the continuous load current does not exceed the 160A rating at the ambient temperature of your enclosure, and confirm that your system’s prospective short circuit current does not exceed 200 kA at the point of installation. If your application operates at a lower voltage or requires a different current rating, contact Shansen Enterprises for guidance on alternative 170M Series catalog numbers.

Frequently Asked Questions
What does Class aR mean for the Eaton Bussmann 170M1569D?
Class aR designates a high speed current-limiting fuse specifically rated for semiconductor protection. Unlike general-purpose gG fuses, a Class aR fuse is designed to clear fault currents extremely rapidly — fast enough to prevent the I²t energy from destroying semiconductor junctions in devices such as IGBTs, thyristors, diodes, and MOSFETs. The 170M1569D must be used as part of a coordinated protection scheme for semiconductor equipment; it is not a substitute for branch circuit or motor protection fuses.
What is the difference between the Type D dual indicator and a standard single indicator on the 170M Series?
The Type D dual indicator on the 170M1569D provides two functions simultaneously: a visible local indicator that pops out or changes state when the fuse operates, allowing maintenance technicians to identify a blown fuse at a glance, and an electrical contact output that can be wired to a PLC, relay, or alarm circuit for remote fault signalling. A standard single indicator provides only the local visual signal. The Type D option is preferred in automated production lines and critical drive systems where remote trip indication or alarm annunciation is required.
Is the 170M1569D suitable for DC applications such as DC drives and DC common bus systems?
Yes. The Eaton Bussmann 170M Series is widely applied in DC common bus and DC drive protection. While the catalog specifies a 690V AC rating, Eaton publishes DC voltage ratings for the 170M Series separately — you should consult the Eaton Bussmann 170M Series datasheet or contact Shansen Enterprises to confirm the applicable DC voltage rating for your specific DC bus voltage before installation. DC applications typically have different voltage derating requirements compared to AC, and the correct catalog number must be verified against the DC system voltage.
Which fuse holder or fuse base is compatible with the 170M1569D?
The 170M1569D is built to DIN 43620 DIN 000 format with knife blade contacts. It is compatible with fuse holders, fuse bases, and busbars designed to accept DIN 000 knife blade semiconductor fuses. Common compatible accessories include bolted busbar-type fuse carriers and enclosed fuse holders rated for 690V AC service. Always verify that the fuse holder is rated for the full 200 kA breaking capacity of the system and is suitable for Class aR high speed fuse applications. Contact Shansen Enterprises for specific holder recommendations.
What industries in India commonly use the Eaton Bussmann 170M1569D?
In India, the 170M1569D and similar 170M Series semiconductor fuses are regularly specified in steel plants, aluminium smelters, paper mills, textile manufacturing, cement production, water and wastewater treatment, automotive assembly lines, and oil and gas installations — wherever variable frequency drives, DC drives, soft starters, large rectifiers, or thyristor-controlled equipment is installed. Panel builders in Coimbatore, Chennai, Pune, Ahmedabad, and Hyderabad use these fuses in drive panels, converter cabinets, and power electronics assemblies supplied to process industries across India.
