Circuit-Breaker Design –
Compact, Reliable and User-Friendly
Distribution boards for substantial energy requirements are
generally followed by a number of subdistribution boards
and loads. Particular demands are therefore made in terms
of long-term reliability and safety. That is to say, "supply",
"coupling" and "feeder" functions must be reliably available
over long periods of time. Maintenance and testing must not
involve long standstill times.
SIVACON meets these requirements with circuit-breaker design
components.
Compact and reliable
• High degree of safety by
virtue of type-tested
standard modules (TTA)
• Test and disconnected
position with door closed
• Cubicle dimensions tailored
to circuit-breaker sizes (e.g.
1600 A with 400 mm width
and 3200 A with 600 mm
width)
• For every rated current
range, optimum connection
conditions for cables and
busbars
• Separate function
compartments consisting
of a switching device
compartment, an auxiliary
equipment compartment
and a cable or bar
connection compartment
• High degree of safety for
assembly personnel by
virtue of cubicle separation
on both sides
User-friendly
with Sentron WL
Siemens 3WL non-withdrawable
and withdrawable
circuit-breakers are used for
the rated current range from
630 to 6300 A. This means:
• Free choice of the supply
direction without any
sacrifices in terms of
technical data
• High short-time currentcarrying
capacity for timegraded
short-circuit
protection (up to 400 ms)
assures reliable operation
of sections of the switchboard
not affected by a
short circuit
• Short-circuit protection with
short-time grading control
(zss) for very brief delay
times (50 ms)
• LCD operating current
indication in the control
console (without ammeters
and current transformers)
• Indication and operation
when the door is closed
