Why we need motor protection fuse?

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, six 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 24KV circuits.
