Semiconductor protection series
- Semiconductor protection fuse. UL certified model is available.
The FUJI CR 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.
