■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 transformers-

rectifiers. FUJI Super Rapid Fuses are

designed with a very small total I2t

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 short-

circuiting faults-i.e. when the

SD-36 SM-388 SI-431 SI-429

BLC CR2L CS5F CS10F

semiconductors short or circuits fail the

sound elements will be quickly isolated

from the fault circuits.

■Features

•The total clearing I2t 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.
