FAE Expert Insights
"The 170M series has been the industry standard for semiconductor protection for decades. The 170M5816 is ideal for protecting 160A-200A IGBT modules in 690V motor drive applications. The ultra-low I2t is critical for protecting modern IGBTs - these devices are expensive and sensitive to overcurrent. Bussmann's consistent quality ensures reliable protection across temperature ranges and long-term operation. The breaking capacity of 200kA provides safety margin for even large industrial systems. I've specified this series for hundreds of projects with zero fuse-related failures. I strongly recommend proper I2t coordination analysis for every application."

Frequently Asked Questions
What is the opening time of this fuse?
The 170M5816 opens in less than 1ms at 10x rated current (1600A). At lower overcurrents (2-5x rating), opening time is longer but still fast enough to protect semiconductors. Time-current curves in the datasheet show precise opening times at various currents.
Check time-current curves for specific opening times.
What is the I2t value of this fuse?
The clearing I2t varies with voltage and fault current. At 700V and 10kA fault current, typical clearing I2t is approximately 80,000 A2s. Consult the datasheet for specific values at your operating conditions.
Verify I2t coordination with your semiconductor datasheet.
Can this fuse be used for DC applications?
Yes, the 170M5816 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 size IGBT module can this fuse protect?
The 170M5816 is suitable for protecting IGBT modules rated 150A-200A at 600V-690V. Verify the IGBT datasheet withstand I2t and ensure fuse clearing I2t is less than 80% of IGBT rating. For detailed specifications and application support on bussmann 170M5816, refer to the datasheet or contact our team.
Perform I2t coordination analysis with your specific IGBT module.
What is the recommended torque for mounting?
Bolt-on semiconductor fuses typically require 15-20 Nm mounting torque. Use calibrated torque wrench and verify connection resistance after installation. Proper torque ensures good electrical contact and thermal performance.
Use specified torque values. Verify connections with micro-ohmmeter.
