Earth leakage protective relays: BRR,EL,RRD series
A relay performs contact output when detecting earth leakage. Both ZCT integrated model and ZCT separated model are available.
In the earth leakage relay the breaking mechanism is omitted from the ELCB, and the ZCT and earth leakage tripping device are integrated into a common body.
These relays are available in both instantaneous and time-delay versions.
Generally these relays are used in conjunction with MCCB’s, ACB’s and motor starters.

Semiconductor protection series, Plug-in type(BLC)
Based on a plug typed current limiting fuse, this model reduces the total clearing I2t, as a high-speed current limiting fuse for the purpose of semiconductor protection.
The FUJI BLC 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 -
