Description
Overview
The Eaton Bussmann 170M1565D is a high speed square body semiconductor fuse rated 63 A at 690 V AC, engineered to protect silicon-controlled rectifiers, IGBTs, and other power semiconductor components from damaging fault currents. Constructed to DIN 43620 DIN 000 format with knife blade contacts, it conforms to IEC 60269-4 and carries CE marking and RoHS compliance for use across modern industrial power electronics. The dual fuse indicator (Type D) provides clear visual and remote signalling of a blown fuse, minimising downtime in panel-level installations.

Applications & Selection Guide
The 170M1565D is the correct choice when protecting power semiconductor devices — such as thyristors, diodes, and IGBTs — in converters, DC drives, and rectifier bridges operating on 690 V AC industrial supplies. At 63 A, it fits mid-range drive and converter stages where the fuse must clear fault current faster than the semiconductor’s I²t withstand rating, preventing catastrophic device failure.
Class gR designation means this fuse provides full-range protection: it handles both overload conditions and prospective short-circuit currents up to 200 kA, making it suitable for high fault-level bus systems. The DIN 000 square body format with knife blade contacts fits standard DIN 43620-compliant fuse holders widely used in European and Indian panel-building practice, reducing sourcing complexity for OEMs and panel builders.
In India, the 170M1565D sees extensive use across Coimbatore’s textile and machine tool industries, Chennai’s automotive manufacturing plants, Pune’s industrial automation sector, and large-scale solar and renewable energy converter installations nationwide. Panel builders and drive manufacturers requiring IEC-certified semiconductor protection with dual indicator output for SCADA integration will find this fuse a dependable, specification-compliant solution.

Frequently Asked Questions
What does Class gR mean for the Eaton Bussmann 170M1565D?
Class gR indicates a full-range semiconductor fuse: the ‘g’ prefix means it can interrupt all fault currents from its minimum fusing current up to its rated breaking capacity (200 kA), and ‘R’ designates it specifically for protecting rectifying semiconductor devices such as thyristors, diodes, and IGBTs. Unlike general-purpose Class gG fuses, the 170M1565D has a much faster I²t characteristic designed to clear fault current before the semiconductor device is damaged.
What is the difference between the Type D dual indicator on the 170M1565D and a standard single indicator?
The Type D dual indicator provides two forms of blown-fuse detection simultaneously: a visible pop-up or drop flag on the fuse body for local visual inspection, and an auxiliary microswitch or contact output that can be wired into a PLC input, relay circuit, or SCADA system for remote fault annunciation. A single indicator typically provides only the visual flag. The dual type is preferred in automated drive panels and converter cabinets where operators may not have direct line-of-sight to the fuse and remote alarm capability is required.
Is the 170M1565D suitable for DC bus applications in VFD panels?
Yes. The 170M1565D is specifically listed for DC common bus and DC drive protection in addition to AC-side semiconductor protection. However, DC voltage ratings differ from AC ratings — always verify the manufacturer’s DC voltage derating data from the Eaton Bussmann 170M Series datasheet for your specific DC bus voltage before applying this fuse on the DC side of a converter. Shansen Enterprises can assist with datasheet review and application confirmation.
Which fuse holder is compatible with the Eaton Bussmann 170M1565D?
The 170M1565D uses a DIN 43620 DIN 000 format square body with knife blade contacts. Compatible fuse holders include Eaton Bussmann 170H Series DIN 000 fuse holders and other DIN 43620-compliant bases from panel component suppliers. Ensure the fuse holder is rated for at least 690 V AC and 63 A continuous current, and that it accommodates the Type D dual indicator output if remote signalling is required. Contact Shansen Enterprises for holder recommendations specific to your panel design.
Does the 170M1565D carry CE marking and is it RoHS compliant?
Yes. The Eaton Bussmann 170M1565D is CE Marked and RoHS Compliant, confirming it meets European Union directives for low voltage electrical equipment and restriction of hazardous substances. These certifications are also accepted for project compliance documentation on Indian infrastructure and export-oriented manufacturing projects that mandate CE-marked components.
