Applications & Selection Guide
The 170M6813D is designed for semiconductor protection in high-power drive and converter panels operating at 690 V AC. Its Class aR rating means it is specifically optimized to open before semiconductor junction damage occurs during overcurrent events — making it the correct choice wherever IGBTs, SCRs, GTOs, or diode bridges are used in DC common bus architectures, VFD input/output stages, and rectifier assemblies. It should not be substituted with general-purpose gG fuses, which are too slow to protect semiconductor junctions.
Typical installation scenarios in India include medium and large VFD panels for pump and fan applications, regenerative DC drives in steel and paper mills, power converter cabinets in renewable energy and UPS systems, and thyristor-controlled soft starter assemblies used in cement, textile, and automotive manufacturing plants. The DIN 3 knife blade format ensures compatibility with widely available fuse holders and switch-disconnectors from Eaton and other manufacturers.
When selecting this fuse for a panel, verify that the prospective short-circuit current at the installation point does not exceed 200 kA, and confirm that the fuse holder or switch-disconnector is rated for DIN 43620 DIN 3 blades at 690 V. For DC bus applications, consult the Eaton 170M Series DC voltage derating tables.

Frequently Asked Questions
What does the Class aR rating mean for the 170M6813D?
Class aR denotes a current-limiting fuse with a partial range breaking capacity, specifically engineered for semiconductor protection. Unlike Class gG general-purpose fuses, a Class aR fuse opens extremely rapidly during overcurrent events to prevent thermal and electrical damage to IGBTs, SCRs, diodes, and other semiconductor junctions. The 170M6813D should always be used in combination with a suitable upstream back-up fuse or circuit breaker that covers the lower overcurrent range not handled by the aR fuse alone.
Is the 170M6813D suitable for DC bus applications in VFD panels?
Yes. The Eaton Bussmann 170M Series is widely used for DC common bus and DC drive protection. However, the rated voltage of 690 V stated on the fuse is the AC voltage rating. For DC applications, the permissible DC voltage is lower and depends on the circuit configuration (grounded or ungrounded). Always refer to the Eaton Bussmann 170M Series datasheet DC voltage derating tables before applying this fuse on a DC bus. Shansen Enterprises can provide the relevant technical documentation on request.
What fuse holder or switch-disconnector is compatible with the 170M6813D?
The 170M6813D is built to DIN 43620 DIN 3 format with knife blade contacts. It is compatible with Eaton Bussmann DIN 3 fuse holders and switch-disconnectors designed for the 170M Series, as well as third-party DIN 3 rated fuse bases rated at 690 V and 900 A or above. Always confirm that the fuse holder is rated for the same voltage, current, and short-circuit breaking capacity as the fuse itself before installation.
How does the dual indicator (Type D) work on the 170M6813D?
The Type D dual indicator provides two forms of blown-fuse indication simultaneously. The first is a visual pop-up flag visible on the fuse body itself, allowing maintenance personnel to identify a blown fuse by sight during panel inspection. The second is an auxiliary microswitch output that can be wired into a PLC, SCADA system, or alarm circuit to provide remote trip signaling and event logging. This dual functionality reduces downtime by enabling both local and remote detection of fuse operation.
What industries in India commonly use the Eaton Bussmann 170M6813D?
The 170M6813D is widely specified in Indian industries that rely on high-power semiconductor-based equipment. Common sectors include steel and metals (DC drives for rolling mills), textiles (VFD panels for loom and spinning machinery in Coimbatore and Tiruppur), cement and mining (soft starter and drive panels), automotive manufacturing (welding rectifiers and press drives), and renewable energy (solar inverter protection and UPS systems). Panel builders and system integrators across Tamil Nadu and pan-India use the 170M Series as a standard platform for semiconductor protection.
