Description
Overview
The Eaton Bussmann 170M5810D is a high speed square body semiconductor fuse rated at 500 A and 690 V AC, designed for Class aR current-limiting protection of power semiconductor devices. Constructed to the DIN 43620 DIN 2 format with knife blade contacts, this fuse integrates a dual fuse indicator (Type D) for immediate visual and remote fault signalling. With a breaking capacity of 200 kA and full IEC 60269-4 certification, it is a trusted choice for panel builders and OEMs specifying semiconductor protection in variable frequency drives, DC common bus systems, and power converter assemblies throughout India.

Applications & Selection Guide
The 170M5810D is the preferred choice wherever high-power semiconductor devices require dedicated back-up protection against short-circuit overcurrents. Its Class aR characteristic means it is optimised to clear fault currents before the semiconductor junction is damaged — a critical requirement in variable frequency drives (VFDs), soft starters, thyristor stacks, DC bus systems, and industrial rectifier assemblies. The 500 A rating and 690 V voltage coverage make it well suited to the three-phase industrial supply voltages commonly found across Indian manufacturing facilities.
In Indian industries such as steel, cement, automotive, textiles, and process chemicals, power electronics panels are increasingly complex, and semiconductor losses due to inadequate fuse protection are costly. Specifying the 170M5810D in your drive or converter panel ensures that a blown fuse — not a failed IGBT or thyristor — is the worst outcome of a fault event. The dual indicator (Type D) also allows maintenance teams to pinpoint the faulted phase rapidly, minimising production downtime.
When selecting a 170M Series fuse, match the fuse amperage to the semiconductor I²t rating and the system voltage. Always verify that the fuse holder or base is rated for DIN 43620 DIN 2 knife blade contact format and that the indicator output matches your monitoring relay. Shansen Enterprises can assist panel builders in Coimbatore and across India with fuse selection, holder compatibility, and bulk project supply.

Frequently Asked Questions
What does Class aR mean for the Eaton Bussmann 170M5810D?
Class aR denotes a fuse designed exclusively for back-up protection of semiconductor devices. Unlike general-purpose Class gG fuses, a Class aR fuse clears fault currents extremely rapidly — fast enough to protect sensitive components such as IGBTs, thyristors, and diodes from thermal damage. The 170M5810D should always be used in conjunction with an appropriately rated semiconductor device and not as a substitute for branch circuit or cable protection.
Is the 170M5810D suitable for DC bus applications in VFD panels?
Yes. The Eaton Bussmann 170M5810D is listed among the recommended applications for DC common bus and DC drive protection. For DC applications, always confirm the DC voltage derate factor for the specific system voltage with reference to Eaton’s published DC application guidelines, and verify with Shansen Enterprises or Eaton technical support that the fuse I²t characteristic is compatible with the semiconductor device being protected.
What fuse holder or base is compatible with the 170M5810D?
The 170M5810D is built to the DIN 43620 DIN 2 format with knife blade contacts. Compatible fuse holders and bases must be rated for this format, capable of carrying at least 500 A continuously, and rated for 690 V AC. Eaton Bussmann offers a range of dedicated fuse bases and mounting hardware for the 170M Series. Contact Shansen Enterprises with your panel specifications and we can recommend the correct holder and bus bar accessories for your application.
What is the interrupt rating of the 170M5810D and why does it matter?
The 170M5810D has an interrupt rating — also called breaking capacity — of 200 kA. This means the fuse can safely clear prospective fault currents up to 200 kA without rupturing, arcing, or causing a secondary failure. In industrial installations in India where transformer fault levels can be high, specifying a 200 kA-rated fuse ensures the protection device itself does not become a hazard during a fault event.
How does the dual fuse indicator (Type D) on the 170M5810D work?
The dual indicator (Type D) provides two forms of fault signalling: a visible striker pin or flag that pops out upon fuse operation for direct visual inspection, and a microswitch or remote contact output that can be wired to a PLC, alarm relay, or panel indicator light. This combination allows both local maintenance personnel and remote monitoring systems to detect a blown fuse immediately, reducing diagnostic time and production downtime in critical drives and converter applications.
