The following are important criteria for selecting switchgear
suitable for export:
For motor-protective circuit
breakers
Use inherently short-circuit
proof switches capable
of controlling the highest
prospective fault levels at
the point of installation
without the need for back-
up protection.
Advantage:
●
●
●
For circuit breakers
Use types with visible
contacts, quick-make and
quick-break operation as
standard. Use current-limiting
circuit breakers for high short-
circuit levels. Selective
switches are recommended
for the selective graduation
of networks.
Advantage:
●
●
●
No restrictions whatsoever
for installation
Complete independence
from the on-site protective
system
No problems getting
spare parts
Independence from local
accident prevention
regulations requiring visible
contacts and safety faults
caused by inexperienced
operating personnel.
The effects of short-
circuits are kept to a
minimum.
Fuseless installations
offer greater safety and
reliability in plant operation.
In the event of a fault, only
the faulty section of the
system is isolated.
For contactors
Use contactors whose entire
range provides consistently
reliable operation in the event
of voltage drops (consistently
down to 80% U
aimed for) and whose contact
system will not assume an
indeterminate position either
on closing or on opening in
such conditions.
Advantage:
●
During electrification
work in areas such as
Africa and the Middle East,
an insufficient voltage
stability is—at least for a
certain time—likely in
many applications (for
example due to long spur
lines or small local
generators). The use of
devices that fulfill the
above requirements will
eliminate one of the main
failure causes related to
contactors.

For enclosures
Use insulated enclosures
with transparent covers
(i.e., “totally insulated”
enclosures).
Advantage:
●
●
Total insulation is the best
possible protective
measure from the user’s
point of view, avoiding
reliance on the possibly
doubtful skills of unknown
installation personnel.
Furthermore, protective
measures based on
earthing are often
extremely difficult, if not
impossible (in the Middle
East, for example, due to
the dryness of the ground).
Insulated enclosures
completely eliminate the
need for any additional
protection against
corrosion. The transparent
covers contribute
significantly to the correct
operation of a system,
because switchgear
operation can be
monitored even with the
doors or covers closed,
thus virtually eliminating
the possibility of these
being left open through
carelessness. The
transparent cover is an
important contribution to
safety, especially where
exports to areas of
uncertain skills are
concerned.
XT IEC Power Control
For overcurrent protective
devices
Always use circuit breakers
and motor-protective circuit
breakers. Avoid fuses as
much as possible.
Advantage:
●
The operational reliability of
a system is especially
important for export
contracts. Circuit breakers
and motor-protective
circuit breakers provide
this reliability in full
measure since they can be
immediately reclosed once
a fault has been cleared,
they disconnect all poles,
they have ideal protection
through high tripping
accuracy and they can be
used for selective
operation. Because they
have no fuses or other
consumables, they also
greatly reduce the problem
of obtaining replacement
parts. The advantages of
fuseless design for export
are especially evident in
this case. No complicated
investigation is needed to
find out which fusing
system is used in the
respective location and
which specifications have
to be followed to select the
correct fuses. Often
several different fuse
systems with widely
varying characteristics are
used side-by-side in the
same country. For the
uninitiated, it may be
almost impossible to find
the right fuse in these
circumstances. These
problems do not arise
where a circuit breaker
is used.
