Applications & Selection Guide
The 170M1572D is the preferred semiconductor protection fuse for power electronic equipment operating at 315 A on 690 V AC industrial networks. Its Class aR rating means it is optimized exclusively for semiconductor protection — it will clear fault currents before the I²t withstand limit of the protected device is exceeded, a performance characteristic that standard gG or gR fuses cannot reliably deliver at these current levels. This makes it mandatory in designs where IGBT modules, thyristor bridges, diode rectifiers, or SCR stacks are used.
Typical Indian industry applications include steel and aluminum rolling mills, cement plant drives, textile machinery VFD panels, chemical process rectifiers, induction furnace power supplies, and traction converter assemblies. Panel builders and OEMs working on export-grade switchgear or drives cabinets will also find this product meets CE marking requirements out of the box. The DIN 00 knife blade format integrates directly with standard DIN 43620-compatible fuse holders and bus bar mounting systems widely used in Indian MCC and PCC panels.
When selecting the correct 170M Series fuse, match the fuse amperage to the semiconductor device’s rated RMS current and verify that the fuse I²t (let-through energy) is below the device’s rated I²t withstand. Eaton’s fuse selection software and application engineering support — accessible through Shansen Enterprises — can assist with this calculation for complex multi-drive or converter topologies common in Coimbatore’s manufacturing base and across Indian industry.

Frequently Asked Questions
What does Class aR mean for the Eaton Bussmann 170M1572D?
Class aR is an IEC 60269-4 designation for fuses designed exclusively for semiconductor device protection. Unlike Class gG fuses that protect cables across the full overload and short-circuit range, Class aR fuses are optimized to clear only high-magnitude short-circuit currents extremely fast — within microseconds — to keep the let-through energy (I²t) below the withstand rating of IGBT modules, thyristors, SCRs, and diodes. The 170M1572D should always be used in conjunction with a suitable upstream overcurrent protective device for overload protection of the circuit.
Is the 170M1572D suitable for DC bus and DC drive applications?
Yes. The Eaton Bussmann 170M1572D is specifically listed for DC common bus and DC drive applications. When used on DC circuits, the applicable voltage rating must be confirmed against the DC voltage of the circuit — consult the Eaton Bussmann 170M Series datasheet or contact Shansen Enterprises for DC application guidance to ensure correct derating is applied.
What is the significance of the Dual Indicator Type D on this fuse?
The Dual Indicator (Type D) means the 170M1572D is fitted with two striker or visual indication pins, one on each end of the fuse body. When the fuse operates (blows), both indicators are released simultaneously, providing a clear and unmistakable visual signal from either side of the panel. This speeds up fault diagnosis and reduces the time technicians spend locating a blown fuse in multi-fuse assemblies such as DC bus panels or converter racks — a significant advantage in minimizing production downtime in industrial plants.
Which fuse holder or base is compatible with the 170M1572D?
The 170M1572D is built to the DIN 43620 DIN 00 format with knife blade contacts. It is compatible with DIN 43620-compliant fuse holders designed for the DIN 00 size — these are widely available from Eaton and other manufacturers. The knife blade contacts must match the blade dimensions specified in DIN 43620. Shansen Enterprises can supply compatible fuse holders and mounting hardware alongside the fuse to ensure a complete, verified assembly.
Does the 170M1572D carry CE marking and RoHS compliance?
Yes. The Eaton Bussmann 170M1572D is CE Marked and RoHS Compliant, confirming it meets applicable European Union directives for low voltage electrical equipment and restriction of hazardous substances. These certifications are important for OEMs and panel builders in India who manufacture equipment for export to European markets or for multinational end-users who require CE-compliant Bill of Materials on their drives and converter panels.
