Applications & Selection Guide
The 170M1558D is specified wherever semiconductor devices — including IGBTs, thyristors, MOSFETs, and diodes — require upstream fast-acting fuse protection. At 10 A and 690 V AC, this fuse is suited for the control and gate drive supply branches of medium and large VFD panels, soft starter input circuits, and rectifier bridge protection in DC common bus architectures. Its Class gR rating ensures it operates within the I²t limits required to protect semiconductor junctions before thermal damage occurs.
In Indian industries such as textile machinery, pump control panels, CNC machine tools, steel processing lines, and renewable energy inverter assemblies, the 170M Series is widely accepted by OEMs and panel builders. The DIN 000 knife blade format simplifies integration into locally manufactured switchgear cabinets and imported drive enclosures. When selecting this fuse, confirm the I²t withstand rating of the semiconductor device is greater than the let-through I²t of the 170M1558D under the worst-case fault condition at your installation voltage.

Frequently Asked Questions
What does Class gR mean for the Eaton Bussmann 170M1558D?
Class gR is an IEC 60269-4 fuse classification for full-range semiconductor protection fuses. Unlike general-purpose Class gG fuses, a Class gR fuse is designed to operate at the very fast speeds required to limit let-through energy (I²t) to levels that semiconductor devices such as IGBTs, thyristors, and diodes can safely withstand. The 170M1558D will clear both overload and short-circuit faults within the protective envelope of the downstream semiconductor.
Can the 170M1558D be used on a DC common bus system?
Yes. The Eaton Bussmann 170M1558D is explicitly listed for DC common bus applications. When applying this fuse on DC circuits, verify the DC voltage rating from the Eaton datasheet and ensure the rated DC voltage is not exceeded. Contact Shansen Enterprises for the full Eaton datasheet confirming DC voltage capability for your specific application.
What is the significance of the Dual Indicator (Type D) on the 170M1558D?
The Dual Indicator Type D provides two methods of blown-fuse detection: a visual indicator flag that pops visibly when the fuse operates, and an electrical microswitch or remote contact output that can be wired into a PLC or control circuit to generate an alarm or trip signal. This is especially valuable in large panels or enclosed drives where direct visual inspection of the fuse during operation is not practical.
Is the Eaton Bussmann 170M1558D compatible with standard DIN 000 fuse holders available in India?
Yes. The 170M1558D is manufactured to DIN 43620 DIN 000 format with knife blade contacts, which is a globally standardised form factor. It is dimensionally compatible with DIN 000 fuse holders and switch-fuse disconnectors from Eaton and other manufacturers that conform to DIN 43620. Shansen Enterprises can supply matching Eaton fuse holders and disconnectors alongside this fuse.
What industries in India commonly use the Eaton Bussmann 170M Series semiconductor fuses?
The 170M Series is widely used across Indian industries including textile machinery (spinning and weaving drives), water treatment and pump stations, steel and metals processing, automotive manufacturing lines, plastic injection moulding machines, paper mills, and renewable energy (solar inverter and wind converter protection). Panel builders and OEMs in Coimbatore, Pune, Ahmedabad, Chennai, and Hyderabad regularly specify the 170M Series for VFD, soft starter, and rectifier protection panels.
