Description Square body US style bolted tags high speed fuses for the protection of DC common bus, DC drives, power converters/rectifiers and reduced rated voltage starters. Available with Type K indicator for microswitches. Specifications Ratings • Volts: • 1250 Vac (IEC) • 1300 Vac (UL) • Amps: 50-1400 A • Interrupting rating: 100 kA RMS Sym. Operating class: aR Agency information • CE • Designed and tested to IEC 60269 Part 4 • UL Recognized* • CSA* • CCC* * Consult your Bussmann series product representative for status. 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) at 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 correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current Catalog Numbers (Amps) Electrical Characteristics -FU/115 Without Indicator -FKE/115 Type K Indicator For Micro Size Amp voltage 170M3688 170M3738 1* 50 1250 Vac (IEC) 1300 Vac (UL) 170M3689 170M3739 63 170M3690 170M3740 80 170M3691 170M3741 100 170M3692 170M3742 125 170M3693 170M3743 160 170M3694 170M3744 200 170M3695 170M3745 250 170M3696 170M3746 315 170M3697 170M3747 350 170M4688 170M4738 1 160 170M4689 170M4739 200 170M4690 170M4740 250 170M4691 170M4741 315 170M4692 170M4742 350 170M4693 170M4743 400 170M4694 170M4744 450 170M4695 170M4745 500 1100 Vac IEC 170M4696 170M4746 550 170M4697 170M4747 630 1000 Vac IEC 170M5688 170M5738 2 250 1250 Vac (IEC) 1300 Vac (UL) 170M5689 170M5739 280 170M5690 170M5740 315 170M5691 170M5741 350 170M5692 170M5742 400 170M5693 170M5743 450 170M5694 170M5744 500 170M5695 170M5745 550 170M5696 170M5746 630 170M5697 170M5747 700 1100 Vac IEC 170M5698 170M5748 800 170M5699 170M5749 900 1000 Vac IEC 170M5700 170M5750 1000 170M6688 170M6738 3 315 1250 Vac (IEC) 1300 Vac (UL) 170M6689 170M6739 350 170M6690 170M6740 400 170M6691 170M6741 450 170M6692 170M6742 500 170M6693 170M6743 550 170M6694 170M6744 630 170M6695 170M6745 700 170M6696 170M6746 800 1250 Vac (IEC) 170M6697 170M6747 900 170M6698† 170M6748† 1000 1100 Vac (IEC) 1000 Vac (UL) 170M6699† 170M6749† 1100 170M6700‡ 170M6750‡ 1250 1000 Vac (IEC/UL) 170M6701‡ 170M6751‡ 1400 †Rated voltage (IEC) 1100. ‡Rated voltage (IEC) 1000V. ¥ UL Recognition at 1000V. • Watts loss provided at rated current. • Microswitch indicator ordered separately.
