Bussmann 方体快速熔断器 170M 系列 分断能力高，灭弧能力强。



1000V (IEC) 50–1400A

Specifications

Description: Square body flush end contact high speed fuses.

Dimensions: See dimensions illustration.

Ratings:

Volts: — 1000Vac. Amps: — 50-1400A

IR: — 150kA (Est. 300kA) RMS Sym.


Agency Information: CE, Designed and tested to IEC 60269: Part 4, UL Recognized.

Electrical Characteristics

Total clearing I2t

The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical

characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms).





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, (rms) 5at a power factor of 15%.

Power Losses 

Watts loss at rated current 1,0is 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, I , in %

b 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

For Other Voltage Ratings in This Body Style

• See pages 124 (690V/700V) and 162 (1250V/1300V)
