The 170M3394-EATON is a high-speed semiconductor protection fuse in the Eaton Bussmann 170M series, rated for 3000A continuous current at 700V AC/DC. Engineered specifically for semiconductor circuit protection, this fuse delivers the ultra-fast clearing characteristics necessary to protect IGBTs, SCRs, diodes, and rectifier modules from catastrophic overcurrent events. With low I²t values and precise arc energy control, it is built to interrupt fault current before thermal damage propagates to sensitive power semiconductor junctions — a critical requirement in high-power industrial and traction drive systems.

The 170M3394-EATON is widely deployed in AC and DC variable frequency drives, regenerative rectifier bridges, UPS systems, soft starters, traction inverters, and industrial welding power supplies. Its high current rating makes it appropriate for large-scale motor drive cabinets, wind and solar inverter systems, and heavy industrial rectifier banks where semiconductor protection is non-negotiable. OEMs and MRO teams specify this fuse across industries including steel, paper, mining, transit, and process automation wherever robust overcurrent protection of power semiconductors is required at the kilowatt-to-megawatt scale.

Key Features of the 170M3394-EATON:

• 3000A continuous current rating with 700V AC/DC voltage capability for high-power semiconductor protection applications
• Ultra-fast arc clearing characteristic with low I²t values engineered to protect IGBT and thyristor junctions before thermal runaway
• 170M series square-body form factor with industry-standard mounting dimensions for direct retrofit into existing fuse holders and drive cabinets
• High interrupting capacity rated for the fault energy levels produced in large rectifier and inverter assemblies
• Consistent clearing performance across operating temperature range, maintaining selectivity in complex protection coordination schemes
• New OEM construction with traceability documentation available — suitable for MRO replacement and new drive system builds

The Eaton Bussmann 170M series at high current ratings like the 3000A 170M3394 is frequently cited as long-lead-time or difficult to source through standard distribution channels, particularly for plant maintenance teams facing unplanned downtime. As production runs age and OEM drive systems reach mid-to-late lifecycle, procurement windows narrow considerably. ATI Accurate Technology specializes in exactly these sourcing challenges, maintaining strategic inventory of high-current semiconductor fuses, IGBTs, thyristors, and rectifier modules that standard distributors have discontinued or cannot deliver on short timelines.

ATI Accurate Technology is headquartered in Palmetto, Florida and ships the 170M3394-EATON same day on orders received before 5PM EST. Whether you need a single replacement fuse for emergency maintenance or volume quantities for a drive rebuild program, ATI offers competitive pricing and responsive support.
