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 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
Square body flush end contact — 1000V (IEC): 50–1400A
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).
