General description
The Siemens SIMOVAC controller is
an integrated system of contactors and
components arranged for convenient
access within a common enclosure
consisting of one or more free-standing
structural sections. SIMOVAC indoor
sections are normally 36” (914 mm)
wide, 30” (762 mm) deep and 95”
(2,413 mm) tall, while SIMOVAC-AR
indoor sections are normally 36” (914
mm) wide, 40” (1,016 mm) deep and
112” (2,845 mm) tall) as shown in the
figures on the following page.
1,200 A load-interrupter switch sections
are similar but are usually 48” (1,218
mm) wide.
Outdoor controllers are similar except
width increases 6” (152 mm) per
section, height increases to 107.3”
(2,725 mm), and depth increases to
37.4” (950 mm).
The controllers can be arranged to meet
specific customer needs and can be
configured to accept up to two starters
per vertical section as shown in drawing
in right column
The modular compartments of the
section may contain starters, lowvoltage/control
devices or space for
future starters.
In general, each starter unit is divided
into medium-voltage and low-voltage/
control compartments each with
its own door, and has the following
features:
n The low-voltage/control compartment
is isolated from the medium-voltage
compartment of the section with
grounded metal barriers and provides
ample space for relays, terminal
blocks and other control circuit
elements.
n The medium-voltage compartment
contains the vacuum contactor,
primary fuses, current and voltage
transformers (optional), a control
power transformer (if applicable),
a no-load isolating switch, load
connections, and has space for
optional surge protection devices
such as surge limiters. (Refer to the
figure below).
