Applications & Selection Guide
The 170M1564D is purpose-built for semiconductor protection duty in industrial power electronics. Its Class gR designation means it is rated to protect rectifier diodes, SCRs, IGBTs, and thyristor assemblies where the fuse must clear faults faster than the semiconductor’s own I²t withstand limit. Typical installations include DC common bus architectures, variable frequency drives (VFDs), soft starter input and output circuits, industrial rectifiers, and power converter modules operating on 690 V AC systems.
In India’s rapidly expanding manufacturing, metals, cement, textile, and process industries, 690 V drive systems are increasingly common, and the correct selection of a Class gR high speed fuse is critical — a standard gG fuse will not provide adequate semiconductor protection. The 170M1564D at 50 A suits smaller drive modules and converter sub-circuits within larger multi-drive panels, where space-efficient DIN 000 square body housings are already specified.
When selecting this fuse, always verify the semiconductor manufacturer’s recommended I²t and peak let-through current ratings against the 170M1564D datasheet values to confirm coordination.

Frequently Asked Questions
What does Class gR mean and why does it matter for semiconductor protection?
Class gR fuses are full-range current-limiting fuses specifically designed to protect semiconductor devices such as diodes, thyristors, SCRs, and IGBTs. Unlike Class gG general-purpose fuses, Class gR fuses have a much lower I²t let-through energy, enabling them to clear fault currents before the semiconductor junction is damaged. Using a standard gG fuse in place of a gR fuse in a drive or converter circuit is a common and costly mistake — it will not provide adequate semiconductor protection.
What is the voltage rating of the 170M1564D and can it be used on a 415 V AC system?
The 170M1564D is rated at 690 V AC, which means it can be used on any AC system up to and including 690 V — so yes, it is fully suitable for 415 V AC systems commonly found in Indian industrial installations. Using a higher-rated voltage fuse on a lower voltage system is electrically acceptable and does not affect protection performance.
What is the significance of the Dual Indicator (Type D) on this fuse?
The Type D dual fuse indicator on the 170M1564D provides two simultaneous blown-fuse signals: a visual pop-up flag for technician inspection during panel maintenance, and an electrical contact output that can interface with a PLC, alarm relay, or SCADA system for remote fault monitoring. This is particularly valuable in unattended or remotely monitored drive panels where early fault detection reduces downtime.
Is the 170M1564D suitable for DC bus protection in VFD and drive systems?
Yes. The 170M1564D is explicitly rated for DC common bus and DC drive applications. Its high speed current-limiting design ensures that DC fault currents — which lack a natural zero crossing unlike AC — are interrupted rapidly enough to protect the semiconductor devices on the DC bus. Always confirm DC voltage rating from the product datasheet and Eaton application notes for your specific DC bus voltage before installation.
What certifications and compliance markings does the 170M1564D carry?
The Eaton Bussmann 170M1564D is IEC Rated per IEC 60269-4, CE Marked for European conformity, and RoHS Compliant confirming restriction of hazardous substances. These certifications make it suitable for use in both Indian domestic industrial projects and export-oriented machinery and panel builds requiring international compliance documentation.
