Now even more application possibilities In all facets of semiconductorprotection

For decades now, SITOR semiconductor protection fuses have been reliablyprotecting converters, rectifiers, UPS systems and many more devices against

short-circuit as well as cables against overload. In order to fulfill market

requirements, we have extended our program by ultra-fast cylindrical fuses. This

means that now more applications can be reliable protected using the well-proven

SITOR product range.

The advantages of SITOR semiconductor protection fuses at a glance

Extremely fast interruption of currents

Unique combination of semiconductor protection and cable protection minimizes

costs, the space require and the installation costs

DIN and special designs for almost all applications

Rated fuses currents from 1 to 1250 A

High cyclic load capacity ensures ageing-free operation

Available with characteristics aR, gR and gS

Ultra-fast cylindrical fuses with a wide range of accessories are now available

They can be quickly supplied thorugh our central warehouse in Amberg

ApplicationsFeatures

SITOR fuse links protect converters against short-circuit.

The power semiconductors used in these devices (diodes, thyristors, GTOs

and others) require fast-switching elements to protect them as a result of

their low thermal capacity. SITOR fuse links are admirably suited for this

type of application (fuse links for semiconductor protection with super-fast

characteristics).

The following fault situations involving

short-circuits can occur:

Internal short-circuit:A defective semiconductor compo-

nent causes a short-circuit within the

converter

External short-circuit:

A fault in the load causes a short-cir-

cuit at the output of the converter

Inverter commutation faults:

If the converter control fails when in

the inverter mode (commutation

faults), then the converter circuit

forms a short-circuit connection be-

tween the DC voltage and AC voltagesupply.

Fuse links can be arranged in various

ways within the converter circuit. A dif-

ferentiation is made between the phasefuses in the three-phase feeder cables

as well as, if required, DC current fuses

and branch fuses in the branches of the

converter circuit (diagrams 5-1 to 5-6).

For center-tap circuit configurations,

fuse links can only be located in the

three-phase feeder cables as phase

fuses.

When using SITOR fuse links, utilizationCategory aR, the overload protection of

the converters up to approx. 350% of

the rated current is handled using

conventional protective devices (e.g.

thermally delayed overload relays).

For closed-loop converters, overload

protection is provided by the current

limiting (exception: general-purpose

fuses).

3NE1...-0 SITOR fuse links, utilization

Category gS are, in addition to providing

semiconductor protection, also de-signed for overload and short-circuit

protection for cables, conductors and

busbars. All of the other double func-

tion fuses belonging to the SITOR series

have gR characteristics. Overload pro-

tection is guaranteed if the rated cur-

rent of the 3NE1..-0 SITOR fuse link is

selected corresponding to InIz(DIN VDE 0100 Part 430).

The rules as laid-down in DIN VDE 0100

Part 430 must be applied when dimen-

sioning the fuse links to provideshort-circuit protection for cables, con-

ductors and busbars.

Important Information

StandardsSITOR fuse links comply with the follow-

ing Standards and regulations:

DIN VDE 0636, Part 40

IEC 60 269-4

When appropriately noted in Sections 2

and 3 Ordering and engineering dataand Characteristics and dimensiondrawings, SITOR fuse links also fulfillthe following Standards and regula-

tions:

IEC 60 269-2-1

VDE 0636/201

(for insertion in l.v.h.b.c. fuse bases

according to VDE 0636/201 as well as

in fused-switch disconnectors and dis-

connectors with fuses)

u

The following Sitor fuse links and

l.v.h.b.c. fuse bases areu recognized:

IEC 60 269-4-1VDE 0636/401

(for bolting to busbars) SITOR fuse

links, Sizes 1 to 3 with an inside cali-

per of 110 mm can also be inserted in

l.v.h.b.c. fuse bases according to

IEC 60 269-2-1 as well as in fused

switch disconnectors and switch dis-

connectors with fuses.

All of the SITOR fuse links with rated

voltages Vn1000 V have the CEmarking in compliance with the

Low-Voltage Directive 73/23/EEC. The

CE marking confirms that the products

are in compliance with the require-

ments as laid down in the Directive.

Environmentally-friendlyrecycling

In 1995, seven German manufacturers

of l.v.h.b.c./h.v.h.b.c. fuse links founded

a non-profit association.

l.v.h.b.c./h.v.h.b.c.Recycling

The objective is to practically and sensi-

bly recycle fuse links and to define an

acceptable disposal concept which ful-

fills all of the requirements of today's

environmental protection legislation.

The used fused links are collected,

sorted and then recycled without the

packaging; materials which have been

melted and recovered are then recycled.

According to the rules and regulations

of the association, excess funds from

the recycling process are donated to a

university to promote research in the

area of fuse links.More detailed information is available

Liability exclusionThe products described here were

developed as part of a complete system

or machine to assume safety-related

functions. Generally, a complete

safety-related system includes sensors,

evaluation units, signaling devices and

concepts for safe shutdown. It is the

responsibility of the manufacturer of a

plant or machine to ensure that his

complete plant or machine functions

correctly. Siemens AG, its regional

offices and associated companies(known in the following as "Siemens")

are able to guarantee all of the proper-

ties and characteristics of a complete

plant or machine which Siemens itself

did not design.

Siemens does not accept any liability for

the recommendations which are either

provided or implicitly provided in the

following document. The information in

this document does not represent a new

guarantee, warranty or liability claims

which extend beyond Siemens generalconditions of supply.

CautionOnly fully authorized and trained

personnel may install and use fuses.
