Medium Voltage Fuses  
British Standard dimensioned IEC fuses for  
motor circuit protection  
The Cooper Bussmann® range of motor fuses are designed  
to meet the specific requirements necessary for motor  
protection. During the starting cycle of direct on-line motors,  
the fuse elements will reach a considerably higher  
temperature than during normal operation; (this is due to the  
high amount of current the motor will draw as it starts,  
typically, 6 times its normal load current value). This results  
in expansion and contraction of the fuse elements and could  
cause premature operation of the fuse.  
Cooper Bussmann® motor fuses encompass an advanced  
design to minimize this effect. This therefore, negates the  
need to over specify the fuse rating due to high values of  
motor starting current.  
Cooper Bussmann® motor fuses operate extremely quickly  
under heavy fault currents, resulting from the time / current  
characteristic. Low power dissipation ensures low  
temperature rise, important in multi-tier starters for example.  
Switching (Arc), voltages are lower than permitted values,  
therefore, 5.5kV fuses are also suitable for 4.8kV and  
2.4kV circuits.
