Semiconductor protection series CS5F,CS8F type
Easy-handling semiconductor protection fuse for small outline dimensions and square shape.
The FUJI CS type is an extremely reliable fuse which has been specially developed to provide protection for silicon diodes and thyristors and is suitable for inverters using semiconductors or transformers-rectifiers.
FUJI Super Rapid Fuse is designed with a very small total I2t value which gives it a high speed interrupting action in the face of abnormal currents.
In addition, the arc voltage generated at the time of interruption has a low value so that faults will not influence related electric machinery and equipment.
This fuse can carry out theprotection of many types of circuits rating from the semiconductor overcurrents to destructive short-circuiting faults-i.e. when the semiconductor short or circuits fail the sound elements will be quickly isolated from the fault circuits.

  • The total clearing l 2 t is low.
    Greater protection for semiconductor elements is ascertained.
  • Easy to install with square body.
    Easy to handle, small outlined dimensions and squared body.
  • High breaking capacity
    CS5F type・・・AC500V 200kA
    CS8F type・・・AC800V 200kA
  • An attachable blown-fuse indication switch available
    A switch (1a or 1b) starts functioning when a fuse starts melting, is attachable.
  • Durability for repetitive current
    Inverters, for example, are associated with harsh change of current due to its characteristics; consequently a large amount of current withstandability for repetitive current is required.
