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.
