For other voltages, the clearing I[2] t 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 . **==> picture [463 x 135] intentionally omitted <==** **----- Start of picture text -----**<br> 1.5 K 2.0 UL 1.00.8 Kp<br>1.6<br>1.0 0.6<br>1.2 0.5<br>10 [3] 0.4<br>0.5 800 0.3<br>0.3 1) 600 2) 0.2<br>500<br>0.2 1)<br>2) 400<br>0.15 Eg 300 Eg 0.1 Ib<br>100 250 400 500 100 200 300 400 500 30 40 50 60 70 80 90 100%<br>1) 35-800 Amp Range 1) 35-200 & 1000-1600 Amp Range<br>2) 1000-1600 Amp Range 2) 225-800 Amp Range<br>**----- End of picture text -----**<br> ## **Dimensions** Fig. 1: 35-1200 Amp Range **==> picture [107 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> Fig. 2: 1400-1600 Amp Range<br>**----- End of picture text -----**<br> **==> picture [448 x 83] intentionally omitted <==** **----- Start of picture text -----**<br> 10.219<br>A 0.125 0.5 3.219 0.625<br>D 1.625<br>1.750<br>E<br>C H 3.5<br>G F B<br>0.75<br>6.219 4.25<br>J 8.969<br>**----- End of picture text -----**<br> |**Order #**<br>**Fig.**|**A**|**B**<br>**C**<br>**D**<br>**E**<br>**F**<br>**G**<br>**H**<br>**J**| |---|---|---| |FWH-35B-60B<br>1|3.188|0.813<br>1.593<br>2.541<br>2.193<br>0.344<br>0.719<br>0.125<br>0.518| |FWH-70B-100B<br>1|3.625|0.947<br>1.736<br>2.853<br>2.807<br>0.352<br>0.750<br>0.125<br>0.375| |FWH-125B-200B<br>1|3.625|1.156<br>1.836<br>2.892<br>2.768<br>0.344<br>1.000<br>0.188<br>0.406| |FWH-225A-400A<br>1|4.340|1.500<br>2.090<br>3.440<br>2.750<br>0.410<br>1.000<br>0.250<br>0.750| |FWH-450A-600A<br>1|4.340|2.000<br>2.090<br>3.530<br>2.780<br>0.410<br>1.500<br>0.250<br>0.780| |FWH-700A-800A<br>1|6.340|2.500<br>2.090<br>4.970<br>3.440<br>0.530<br>2.000<br>0.380<br>1.300| |FWH-1000A-1200A<br>1|6.969|3.000<br>3.219<br>5.465<br>4.475<br>0.625<br>2.375<br>0.438<br>1.120| |FWH-1400A-1600A<br>2||See Drawing| Dimension in inches. 1mm = 0.0394∑ 1∑ = 25.4mm The only controlled copy of this BIF document is the electronic read-only version located on the Bussmann Network Drive.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
