Fuse values for URING36-F switchgear depend on the voltage and power (kVA values) of the transformer to be
protected and also depend on the MV fuse manufacturer.
Fuse selection tables according to manufacturers are below. Select the fuse current from the lists below according
to the power of the transformer you will use and according to the fuse brand you will use.
Use fuse with thermal protection.(The fuse not allowed without thermal protection. Otherwise
Use Fuse with ≥80N pin stiker force.
NOTE:
If the switchgear operation voltage is different than 36kV, consult the sales department for appropriate fuse
nominal value and fuse adapter.
