1000V (IEC) 20-315A
Specifications
Description: Square body DIN 43
653 stud-mount high speed fuses.
Dimensions: See dimensions
illustration.
Ratings:
Volts: — 1000Vac (20-250A)
— 900Vac (315A)
Amps: — 20-315A
IR: — 150kA 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 elec-
trical characteristics. For
other voltages, the clearing
I2t is found by multi-plying 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 dur-
ing its operation as a func-
tion 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 char-
acteristics. 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
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
