Square Body DIN 43 620 — 690V (IEC/UL): 10-315A blade style high speed fuses
Specifications
Description: Square body DIN 43 620 blade style high speed fuses.
Dimensions: See dimensions illustration.
Ratings: Volts: — 690Vac
Amps: — 10-315A
IR: — 200kA 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).
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.

• Watts loss provided at rated current.
• Microswitch indicator ordered separately.
See accessories on pages 185-186.
Rated Current
The rated current of this fuse range has been given with copper conductors that have a current density of 1.3 A/mm2 (IEC 60269-4). For conductor cross section according to IEC 60269-1, the fuses with a rated current higher than 125A must be derated. Please contact Cooper Bussmann for application assistance.
