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 together with fuse bases, fuse screw caps
and accessories 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
expensive devices and system components such as semicon-
ductor 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.
If using fuse bases and fuse screw caps made of molded plastic,
always take into account the maximum permissible values of
power loss due to the high power dissipation (power loss) of the
SILIZED fuses.
If using these components, the following maximum permissible
power losses apply:
•
NEOZED D02: 5.5 W
•
DIAZED DII: 4.5 W
•
DIAZED DIII: 7.0 W.
For this reason, in some cases, 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.
■
Benefits
•
SILIZED fuses have an extremely compact design. This
means they have a very small footprint – particularly the
NEOZED version.
•
The rugged and well-known DIAZED design complies with
IEC 60269-3. It is globally renowned and can be used in many
countries.
•
A huge range of fuse bases and accessories are available for
the NEOZED and DIAZED versions of the SILIZED fuses. This
increases the application options in many devices.
