Description
Overview
The Eaton Bussmann 170M1567D is a high speed square body semiconductor protection fuse rated at 100 A and 690 V AC, designed to protect thyristors, diodes, IGBTs, and other semiconductor components in power electronics systems. Part of the proven Bussmann 170M Series, it conforms to DIN 43620 DIN 000 format with knife blade contacts, making it a direct-fit solution for standard semiconductor fuse holders used across industrial drive and converter panels in India. Its dual fuse indicator (Type D) provides clear visual and auxiliary signalling of a blown fuse, minimising downtime in critical installations.

Applications & Selection Guide
The 170M1567D is the correct choice when you need Class aR semiconductor protection at 100 A in a 690 V AC system. Class aR fuses are designed exclusively for semiconductor protection — they operate faster than general-purpose Class gG fuses, clearing fault current before the i²t energy can damage expensive thyristors, diodes, or IGBTs. This makes them mandatory in converter and drive designs where semiconductor replacement costs and downtime far exceed the cost of the fuse itself.
Typical applications in India include variable frequency drives (VFDs) used in pumps, fans, and compressors across water treatment, cement, and steel plants; DC common bus systems and rectifier bridges in heavy industry; soft starters in motor control centres (MCCs); and thyristor stacks in resistance welding, electroplating, and induction heating equipment. The DIN 000 knife blade format is widely supported by panel builders across Coimbatore, Chennai, Pune, and other manufacturing hubs.
When selecting this fuse, verify that your fuse holder or busbar system accepts DIN 43620 DIN 000 knife blade contacts and that the I²t let-through value of the 170M1567D is below the I²t withstand rating of the semiconductor device being protected. Consult the Eaton Bussmann 170M Series datasheet or contact Shansen Enterprises for application engineering support.

Frequently Asked Questions
What does Class aR mean and why is it required for semiconductor protection?
Class aR (current-limiting, restricted range) fuses are specifically designed to protect semiconductor devices. Unlike general-purpose Class gG fuses that operate across a wide overload range, Class aR fuses are optimised to clear faults extremely fast — limiting the let-through energy (I²t) to a value that the semiconductor can survive. Using a Class gG fuse in a semiconductor circuit will typically result in device destruction before the fuse operates, making Class aR the correct and necessary choice for drives, converters, and thyristor circuits.
What is the DIN 43620 DIN 000 format and which fuse holders accept the 170M1567D?
DIN 43620 is the German standard defining the physical dimensions of square body semiconductor fuses, with DIN 000 being a specific size class within that standard. The 170M1567D uses knife blade contacts and a square body housing that conform to this format. Compatible fuse holders include Eaton Bussmann DIN 000 series holders as well as third-party DIN 43620 DIN 000 rated holders from other manufacturers. Always confirm current rating and voltage compatibility of the holder before installation.
What does the Dual Indicator (Type D) on the 170M1567D provide?
The Type D dual indicator provides two forms of fuse-blown notification. First, a visual pop-up indicator gives a clear local signal that the fuse has operated — essential for quick identification during panel inspection. Second, the Type D indicator includes a microswitch or auxiliary contact output that can be wired into a control circuit or PLC input, enabling remote fault annunciation, drive shutdown, or alarm triggering without the need for a technician to open the panel. This significantly reduces fault diagnosis time in automated industrial systems.
Can the 170M1567D be used in DC applications such as DC common bus systems?
Yes. The Eaton Bussmann 170M Series is widely used in DC common bus architectures, DC drive systems, and rectifier bridges. However, DC voltage ratings differ from AC ratings, and you must verify the specific DC voltage rating for the 170M1567D from the official Eaton datasheet before applying it in a DC circuit. Contact Shansen Enterprises or refer to the Eaton Bussmann 170M Series technical documentation for DC application guidance.
Is the 170M1567D a direct replacement for other 100 A DIN 000 semiconductor fuses?
The 170M1567D may be a direct physical replacement for other DIN 43620 DIN 000 format 100 A semiconductor fuses, but electrical compatibility must be verified. Key parameters to cross-check include: AC voltage rating, I²t let-through value, fuse class (aR), and indicator type. Direct substitution without verifying I²t and time-current characteristics can lead to inadequate semiconductor protection. Shansen Enterprises can assist with cross-reference validation against other brands including ABB, Ferraz Shawmut, and Mersen.
