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.
The OTDC range of switch-disconnectors is specially
designed for DC applications. Thanks to a compact design,
efficiency and reliability, OTDC switches bring photovoltaic
installations to the next level.
OTDC 10…32A
• Modular design
• Simple and fast installation
• DIN rail or screw mounted
• Tunnel terminals for easy termination
• Shortcircuit bars are pre-installed as standard
• Maximum engergy efficiency
• Available in plastic enclosure
OTDC 100A….1600A
• ABB offers a compact DC switch range for single and multi circuit disconnecting
• Carefully designed arc plates and dual magnetic breaking, breaking power is
optimized across the entire current range.
• As a result of symmetric pole design, the connections are independent of polarity.
The user can make the connections in both ways.
• OTDC is the only DC switch in the market that has visible contacts.
• The mechanism can be located between the poles or on the side of the switch.
• Special four pole versions can be made for double circuit applications.
• The operation of the switch is not vulnerable to voltage peaks and it is independent
of the user (quick make quick brake).
• The switches are available in direct mounting handle version as well as external door
mounted handle version.
• The power losses are very low, results in high efficiency.
A fully optimized range of two-pole DC switch-disconnectors for 1500V utility-scale
photovoltaic power plants covering 315-800A current range. The new design offers
both a size reduction and an increase in efficiency and performances, helping
manufacturers to adapt quickly to the industry’s rapid adoption of 1500V DC
solutions. A switch range that allows manufacturers and utilities to improve their
systems efficiency, lowering power losses and reducing the size of combiner boxes,
enclosures and inverters.
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.
Auto Transfer Switches 40-4000 A
Technologies for external environment
Complete range 40-4000 A. ABB offers a wide selection of
automatic transfer switches (ATS). They have the features
and functionality that make them suitable for diverse
applications
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.
