High Speed Fuses

160

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.

Features and Benefits

• Excellent DC performance

• Low watts loss

• Superior cycling capability

Typical Applications

• DC common bus

• DC drives

• Power converters/rectifiers

• Reduced voltage starters
