1)
Due to the mechanical stress on the relatively long fuse blades,
SITOR 3NE41 semiconductor fuses should only be switched occasionally
and only at zero current.
2)
Fuses with a rated voltage of >690 V may only be operated at max. 690 V
(rated voltage of the 3KL) when installed in 3KL.
3)
In the case of cyclic loads, the currents may have to be further reduced
(precise values on request).
4)
The fuse can also be operated at a higher rated uninterrupted current than
the 125 A current of the 3KL52. However, in this case, the 3KL52 must not
be switched under load (utilization category AC-20)
