■ Overview
SILIZED is the brand name of the NEOZED fuses (D0 fuses) and
the DIAZED fuses (D fuses) with super quick characteristic for
semiconductor protection. The fuses are used in combination
with fuse bases, fuse screw caps and accessory parts of the
standard fuse system.
SILIZED fuses protect power semiconductors from the effects of
short circuits because the super quick disconnect characteristic
is far quicker than that of conventional fuses. They protect ex-
pensive devices and system components, such as semiconduc-
tor contactors, static relays, converters with fuses in the input
and in the DC link, UPS systems and soft starters for motors up
to 100 A.
When using fuse bases and fuse screw caps made of molded
plastic, always heed the maximum permissible power loss
values due to the high power loss (power dissipation) of the
SILIZED fuses. When using these components, the following
maximum permissible power loss applies:
• NEOZED D02: 5.5 W
• DIAZED DII: 4.5 W
• DIAZED DIII: 7.0 W
For this reason, sometimes a thermal permanent load of only
50 % is possible.
The DIAZED screw adapter DII for 25 A is used for the 30 A fuse
link.
