Gemini, something
completely different in
switchboards
ABB SACE’s Gemini range is
revolutionizing the market of low
voltage electric insulating
1
switchboards.
The reason for this is that it is
the first switchboard made in
thermoplastic material, to which
the co-injection molding technique gives the same mechanical characteristics as polyester .
This means that it is extremely
sturdy , with its rigid covering and
expanded internal core. Moreover, it contains no fiberglass, a
material that with time rises to
the surface, jeopardizing the
functioning and safety of switchboards made in polyester with
which it is usually mixed.
Gemini switchboards have IP66
degree of protection (IP40 with
the door open and with the appropriate components installed)
and a very high resistance to
chemical and atmospheric
agents. This is the reason why
Gemini guarantees excellent
performances even in particularly severe operating conditions.
Introduction
Characteristics of Gemini switchboards
Gemini switchboards are made with co-injection,
which ABB SACE is the first manufacturer in the
electric field to use as a molding technique. This
process obtains a “sandwich” of two materials with a
compact external covering and an expanded core,
guaranteeing the highest level of mechanical
protection against impacts (IK10) without the need to
add hardening substances.
Polyester is usually mixed with fiberglass, which, with
1SLC805003F0001
wear, rises to the surface and can become a risk factor
for skin burns that may occur during installation and
maintenance and accidental contact.
Moreover, it causes deterioration of the technical
strength and lasting characteristics of the material to
which it is added: Gemini, on the other hand, keeps its
mechanical characteristics in the long term.
The co-injection technique makes the manufacturing
operations themselves safe because the products are
completely finished when they come out of the mold
without any flash or other surface irregularities.
Strong outside and
versatile inside,
Gemini is fit for all
applications
There are as many configurations as there are ABB devices
for low voltage automation and
distribution: moulded-case circuit breakers, modular circuit
breakers, monitoring, control
and signaling devices, wiring
ducts and electrical connection
systems.
All of these components give
the “Gemini system” an enormous range of ad hoc solutions
that are easy to assemble with
the snap-on system.

1SLC805002F0001
Nothing can be compared with
Gemini, even when the switchboards have reached the end of
their life cycle: they are totally
ecologically compatible. The
material used to manufacture
them is 100% recyclable. Polyester, on the other hand, cannot be recovered.
Moreover, to make sure that
correct disposal procedures are
followed, instructions are provided about how to identify
materials and what to do with
the product once it has served
its useful purpose.
Quality and safety
ABB’s Gemini is designed and
built in compliance with reference Standards that define its
constructional and functional
characteristics.
In particular, the IP66 degree
certifies that Gemini is totally
protected against the infiltration
of solid bodies and is resistant
to the penetration of jets of water similar to sea waves.
Absolute protection is provided
by double insulation even in the
event of indirect contact. Rated
uninterrupted current can reach
a threshold of 400 A.
Even in very difficult application
circumstances, Gemini gives
high-level performances, with
resistance to fire and abnormal
heat up to a temperature of
750 °C and a functioning temperature from -25 °C to 100 °C.
Moreover, the material with
which it is manufactured retains
its characteristics for a long time
since it is not subject to corrosion by chemical or atmospheric
agents. Also it does not turn
yellow when exposed to UV
rays.
Introduction
Characteristics of Gemini switchboards
Gemini is made in a thermoplastic material that has
a very low halogen content and is 100% recyclable.
The environmental compatibility of Gemini is an
important objective right from the design phase where
the Life Cycle Assessment (LCA) procedure, defined in
1990 during the Society of Environmental Toxicology
and Chemistry Conference (Vermont, USA), is
followed. Life Cycle Assessment is an objective method
for analyzing the energy and environmental loads
relating to a product, process or activity, carried out
by identifying and quantifying energy, the materials
used and emissions released into the environment.
Divided into four phases, the assessment covers the
entire life cycle of the product, process or activity,
from the extraction and transformation of raw
materials to manufacturing and distribution, and
from usage to recycling and decommissioning.

A switchboard that is not
just one system, but three
Gemini is the result of design
work conducted by ABB with
the direct collaboration of
switchboard manufacturers, installers and designers who considered versatility to be the discriminating element when purchasing a switchboard, equally
as important as sturdiness and
reliability.
Gemini fulfils this requirement by
providing a product that can be
used for three different purposes: in addition to the basic
configuration it also provides the
components necessary for
equipping it as an automation
switchboard or as a distribution
and mixed switchboard.
In all applications, compatibility
with ABB protection, control
and monitoring products means
that a real system of integrated
and complementary functions
can be configured.
Typical examples of some
Gemini applications can be
seen in installations in industrial
production departments and on
board machines, in galvanization plants and varnishing cabins, in petrol stations and carwashing plants, boiler-rooms,
car parks, shopping malls and
in any other environments
where distribution and automation demand specific safety requirements and service continuity .
Gemini also has flexible measurements, with six different box
sizes and internal space to accommodate from 24 to 216 DIN
modules.
To respect safety standards, all
the switchboard’s components
can be fixed to the base plate
or to the box frame without ha-
Introduction

Basic configurations
In the basic configuration,
Gemini switchboards are composed of boxes in six different
sizes ranging from 335x400x210
mm to 840x1005x360 mm
(WxHxD, external measurements) and with opaque or
transparent doors.
In both versions, the doors are
reversible and clip onto the
hinges without the need to use
tools; the fact that they open at
an angle of more than 180°
means that it is easy to work on
the components installed inside
the switchboard. The seal applied by extrusion along the
sides of the doors guarantees
IP66 degree of protection. Access to the inside of the switchboard is protected by a standard double bit lock that can be
replaced by locks of another
type available in the accessories.
Boxes and doors can be requested either separately or as
combined “box + door” codes,
to make filling out the order form
more flexible.
Inside the packages, the door
is always wrapped separately
and inserted inside a pocket
that protects it from accidental
damage until wiring is completed and the switchboard is
installed.
Hole-cover plugs to guarantee
IP protection and double insulation for wall mounting are also
supplied with the pack together
with the instruction sheet.
No tools are needed for installation. The doors hook onto the hinges with special
hinge pins and are reversible.
Gemini doors open at an angle of
more than 180° giving easy access to
the devices installed inside the
switchboard.

Gemini switchboards are designed to be perfectly compatible with ABB components for
low voltage control and monitoring.
For these applications they can
be equipped with modular devices belonging to the System
pro M range, with Tmax
moulded-case circuit-breakers
and control and signaling devices, creating a truly integrated
automation system.
When deciding the Gemini layout for control and monitoring
applications, not only is it possible to select the box and door
in the required size, but you can
also select the base plate in one
of the three versions in the
range.
After wiring with the ducts and
the Fix-O-Rapid device, the
special standard adjustable feet
and hooks must be fitted onto
the base plate, allowing it to be
inserted inside the box at up to
seven different depths and
three further levels of adjustment: no tools need to be used
to carry out these operations.
To finish the job, the inner door
can be mounted (reversible and
in insulating material), guaranteeing IP40 degree of protection
when the switchboard door is
open.
No tools are needed unless the
inner door is equipped with buttons, warning lights, etc.
The fixing hooks and feet supplied in
the standard versions are applied
without having to use tools, making it
possible to install the base plate at
seven different depths inside the
switchboard. They can also be
adjusted at three further positions.

In distribution and mixed applications, the Gemini switchboard
is designed to be fitted with System pro M modular devices
and Tmax moulded-case circuit
breakers.
The frame is the load-bearing
element of the configuration:
DIN rails, partial modular plates
and the special Tmax mounting
and cabling kits are snapped
onto the uprights. All the components can be adjusted to six
different depths with a pitch of
12.5 mm and arranged at
heights with a distance of 75
mm between the rows.
Blank or drilled front panels are
applied to protect the equipment and these can be hinged
onto both sides; the cables are
housed inside the vertical wiring duct integrated in the uprights according to an exclusive
ABB patent.
Wiring is carried out by pulling
out the frame and working from
the front; the ergonomic grip
and the standard feet and snapon hooks supplied make it easy
to insert it inside the switchboard after the job is finished.
