Bussmann 方体快速熔断器 170M 系列 分断能力高，灭弧能力强。
690V/700V (IEC/UL) 40-1000A Specifications Description: Square body DIN 43 620 blade style high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts:— 690Vac (IEC) — 700Vac (UL) Amps:— 40-1000A 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 characteris- tics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a func- tion of applied working voltage, Eg, (rms). |
| Arc Voltage 1.4 1.2arc voltage, U , which may This curve gives the peak L9appear across the fuse 8 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 is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correc-tion factor, Kp, is given as a function of the RMS load 0.2current, Ib, in % of the rated current. Features and Benefits • Excellent dc performance Typical Applications • DC common bus |

Dimensions (mm)
Rated Current The rated current of this fuse range has been given with copper conductors that have a current density of 1.3 A/mm2(IEC 60269-4). For conductor cross section according to IEC 60269-1, the fuses must be derated. Please contact Cooper Bussmann for application assistance. |
