FAE Expert Insights
"The 170M5817 is the go-to fuse for protecting 200A-300A IGBT modules in high-power applications. At 200A, it handles the demanding requirements of large motor drives and industrial converters. The 700V rating is perfect for 690V systems common in European industrial applications. I2t coordination is critical at this power level - a failed IGBT can cost thousands of dollars, making proper fuse selection essential. The 170M series has proven reliability with consistent clearing characteristics. Breaking capacity of 200kA provides safety margin for large industrial systems. I recommend this fuse for any high-power IGBT application requiring 200A protection."

Frequently Asked Questions
What size IGBT module can this fuse protect?
The 170M5817 is suitable for protecting IGBT modules rated 200A-300A at 600V-690V. Verify the IGBT datasheet withstand I2t and ensure fuse clearing I2t is less than 80% of IGBT rating for reliable protection.
Perform I2t coordination analysis with your specific IGBT module datasheet.
What is the difference between 170M5816 and 170M5817?
The 170M5816 is rated for 160A continuous current, suitable for 150A-200A IGBT modules. The 170M5817 handles 200A for larger 200A-300A IGBT modules. Both have the same 700V rating and ultra-low I2t characteristics.
Select based on IGBT current rating. 170M5816 for smaller modules, 170M5817 for larger modules.
Can this fuse be used for DC applications?
Yes, the 170M5817 is rated for DC applications up to 700VDC. For DC use, ensure proper fuse holder selection and verify breaking capacity at DC voltage. DC arc interruption requires proper fuse design.
Verify DC ratings in datasheet. Use appropriate DC-rated fuse holders.
What is the opening time of this fuse?
The 170M5817 opens in less than 1ms at 10x rated current (2000A). At lower overcurrents, opening time increases but remains fast enough to protect semiconductors. Time-current curves show precise opening times.
Check time-current curves for specific opening times at your fault current levels.
What mounting hardware is required?
The 170M5817 requires M10 mounting bolts with 15-20 Nm torque. Use calibrated torque wrench and verify connection resistance after installation. Proper hardware ensures reliable electrical and thermal performance.
Use specified M10 hardware with proper torque. Verify connections after installation.
