1Type-Tested Switchgear and
1Controlgear Assembly (TTA)
SIVACON is a type-tested switchgear and
controlgear assembly (TTA) whose physical
characteristics were designed in the test
laboratory both for normal operating conditions
and for fault situations. Conclusive
type tests assure a maximum of reliability
and safety. SIVACON has passed the
following verification tests as detailed in
IEC 60439-1 and DIN EN 60439-1
(VDE 0660 Part 500):
• Verification of temperaturerise
limits by test
• Verification of dielectric
properties by test
• Verification of the shortcircuit
withstand strength
by test
• Verification of the effective
connection between the
exposed conductive parts
of the assembly and the
protective circuit by
inspection or by resistance
measurement
• Verification of the shortcircuit
withstand strength of
the protective circuit by test
• Verification of clearances
and creepage distances
• Verification of mechanical
operation
• Verification of the degree of
protection
Every SIVACON switchboard
assembly undergoes routine
testing before delivery:
• Inspection of the assembly
including inspection of
wiring and, if necessary,
electrical operation test
• Dielectric test
• Checking of protective
measures and of the
electrical continuity of the
protective circuits
These safety requirements
are met by a series of details
in SIVACON, for example:
• With the use of the
withdrawable design,
operating errors are ruled
out by exactly shaped
mechanical guides and
interlocks
• Use is made of only a few,
exclusively high-grade
insulating materials
(e.g. for rail mounts and
reinforcements, etc.)
• Use of reliable Siemens
switchgear reduces the risk
of premature failures
• Reliable disconnection after
70 to 100 ms even in the
event of long delay times by
3WN circuit-breakers with
short-time grading control
• Computer-assisted project
planning assures error-free
selection and placement of
items
• Arcing fault-tested
• Quality management
system to DIN EN ISO 9001
• Environmental management
system to
DIN EN ISO 14001
