ABB has a wide portfolio of low voltage switches. They are
suitable for diverse applications, in motor control centers,
in switch boards and as main switches in various equipments
and machines. From single to 8 poles and combination
switches for change-over, automatic transfer, bypass,
reversing etc.
Switch disconnectors 16 �4000 A
The switch disconnector is largely used as the main switch
in low voltage switchgears for distribution of power,
starting and stopping motors and isolating loads during
maintenance.
The range from 16 to 125 Amps are either base plate or door
mounted by snap-on or screw fitting front operated 3, 4, 6
and 8-pole are available as standard.
From 160 to 4000 Amps the switch disconnectors, also called
load break switches, are designed as pole modules and
they are available as 1, 2, 3 and 4-pole versions, front or side
operated.
Switch disconnector fuses 16 �1250A
The switch disconnector fuse is used as the main switch
in low voltage switchgears in industry for distributing power
and protecting motors, cables and other devices against
short circuits and over loads.
The switch disconnector fuses are available for all types of
fuse links, DIN, BS, NFC, UL, CSA.
The range includes single pole to four pole versions,
front-or side-operated. The pole module design enables
location of the operating mechanism in any position
together with the direction of the terminals giving flexibility
to installation in different types of cubicle designs.
Change-over and transfer switches 16 �3200 A
ABB’s change-over and transfer switches are designed to
transfer loads from one power source to another in a wide
variety of applications.
The range includes switches from 16 to 3200 Amperes, which
can be operated manually, remotely by using a motor or
automatically.
ABB’s change-over and transfer switches are tested
according to IEC 60947-6-1 and IEC 60947-3 standards.
The switches have ratings in AC31 and AC33 utilization
categories, up to 415 V. In motorized switches, the motor
operators have a wide voltage operation range.
Enclosed switches 16 �1600 A
The ABB enclosed switches are suitable for power
distribution in factories and buildings, as local motor
isolators and as main switches. Each incoming supply shall
be provided with a hand operated main switch-disconnector
according to the Machine Directive EN 60204 and isolate
reliably the electrical equipment from the supply.
ABB enclosed switches are designed and tested to meet
these requirements and complies with IEC 60 947-3.
The enclosed switches are easy to install and safe to use
in industrial, public and residential environments. The
indication of the handle is always reliable and lockable in the
OFF-position with a standard padlock. ABB’s long experience
in switch disconnects guarantees a long and safe use.
AEnclosed switches are designed and used as main
switches for applications, which need to be isolated
from the network. The range includes front operated and
side operated switch disconnectors, switch fuses and
changeover switches enclosed in plastic, steel sheet or
stainless steel sheet and aluminium enclosures. They are
rated for utilization categories including disconnecting
as well as making and breaking the load. In addition,
the switch fuses equipped with fuse links protects the
application and the cables from overload currents and
short circuits.
Plastic enclosures
The plastic enclosures are most suitable for locations
with high chemical and moisture requirements.
In addition, they are light and easy to install and handle.
Steel sheet enclosures
The steel sheet enclosures are hot dip galvanized and the
surface is polyester powder painted. The enclosures are
durable and robust for various environments.
Stainless steel sheet enclosures
The stainless steel sheet enclosures are made of AISI 304
stainless steel. They are used particularly in the food and
beverage industry and in locations where high hygieneis required. The smooth surface does not require any
painting and is easy to clean.
Aluminum alloy enclosures
Aluminum enclosures have very good impact strength
and protection against UV light. They are suitable both
for indoor and outdoor use in medium to heavy-duty
applications.
