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.
