170E Square Body High Speed DC Traction Fuse Links 750Vdc 63-500A

  
Description:
Traction flush end square body high speed fuse links for superior protection of DC third rail applications up to 750Vdc.
 
Technical Data
Rated Voltage: 750Vdc (IEC)
Rated Current: 63-500A
Rated Breaking Capacity:
- 100kA at 1000Vdc, L/R 40ms
- 100kA at 750Vdc, L/R 100ms
Operating Class: gR

Electrical Characteristics
Arc Voltage
This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage Eg.

Power Losses
Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current.
 
Features and Benefits
• Excellent DC performance
• Low arc voltage and low energy let-through (I2t)
• Low watts loss
• Superior cycling capability
 
Typical Applications
• DC common bus
• DC drives
• Power converters/rectifiers
• Reduced voltage starters
