Low Voltage Fuses BLC, CR and CS types Super Rapid Fuses BLC, CR and CS types Super Rapid Fuses 150-1500 Volts AC 10-4700 Amps Description The FUJI BLC, CR and CS types are extremely reliable fuses which have been specially developed to provide protection for silicon diodes and thyristors and are suitable for inverters using semiconductors or transformersrectifiers. FUJI Super Rapid Fuses are designed with a very small total I 2 t value which gives them 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. These fuses can carry out the protection of many types of circuits rating from the semiconductor overcurrents to destructive shortcircuiting faults-i.e. when the SD-36 BLC SM-388 CR2L SI-431 CS5F semiconductors short or circuits fail the sound elements will be quickly isolated from the fault circuits. Features * The total clearing I 2t is small and the semiconductor circuit is completely protected. * Since the peak arc voltage at the time of interruption is low damage to other equipment does not occur. SI-429 CS10F * High interrupting capacity of 200kA at 1000V AC * The CS type is provided with a blown fuse indicator. An alarm contact block (1NO or 1NC) can also be attached.
