Stabilise systems with technology.

Stabilise systems with technology.
Electrical power is the lifeline of industry, but it is
unpredictable. Just like an ocean, it can be calm one
moment and turbulent the next. You cannot predict
when a sudden dip or surge will happen, but you can
protect your installation from damage, when it does.
That’s where our highly sophisticated OMEGA ACBs
can make a world of difference to the safety of an
organisation’s employees, systems and infrastructure.
OMEGA ACB range consists of highly compact units
designed for high current, high power applications in
Low Voltage (LV) distribution network systems.
They are equipped with state-of-the-art Matrix
protection and control releases to meet the most
demandin g protection and system co-ordination
requirements. All this, with the assurance of
compliance to the ‘Safe &
Sure’ policy.
L&T Electrical & Automation
Over the last five decades, has earned a place
among the leading manufacturers of
Low Voltage Switchgear in the world, with the scale,
sophistication and range to meet global benchmarks.
E&A In keeping with our leadership position in the Indian
market, we also provide expert assistance in product
selection, installation and effective after-sales service,
across the country.

The OMEGA ACB range has been designed to adapt to
changes in your requirements, and allow you to modify
or upgrade your systems with ease. This means
minimum down-time and enhanced protection at all
times.
•Meet system upgradation needs with
ease throughout the life of your product, with click-
fit, easy-to-mount front accessories like U/V and U/V
delay modules, Shunt and Closing releases.
•Enjoy total system flexibility and scalability
by adding power metering and communication
modules or by enabling/disabling each protection
function, depending on the requirement.
Get the OMEGA advantage
•Let your systems have better co-ordination
with protection devices and downstream loads,
via a wide range of protection curves and
fine adjustment of current pick-up threshold and
time-delay settings.
•Control a vast electrical installation through
Zigbee communication, along with the option of
conventional industrial communication protocols
such as MODBUS and PROFIBUS.
•Customise terminals by configuring terminal
adaptors for Vertical/Horizontal busbar
arrangements, to facilitate termination of
Aluminium and Copper busbars.
Refer page No. 127-129 for recommended busbar
sizes for termination.
•Convert ACBs easily on site from Fixed to
Draw-out or from Manual to Electrical versions.
Meet new challenges easily. 4

Move ahead, swiftly and safely.
OMEGA ACBs offer you the best of both worlds – high
performance coupled with a range of exclusive features
that deliver the highest level of electrical safety.
•Save valuable space with world’s most compact
ACBs, starting at just 347mm in width.
•Enjoy total reliability in even the harshest of
conditions including high ambient temperatures and
humidity levels.
•Savour operational flexibility, as the ACB
discriminates between fault zones selectively,
allowing downstream equipment to clear the fault in
a prescribed time before intervening.
Performance par excellence
Negating human error with safety features
•No Arc-chute, No closure: Unique features like
Arc-chute Interlocking and True Ready-to-Close
(RTC) detection systems ensure that the ACB closes
only when the Arc-chutes are in place and all other
pre-requisite conditions are fulfilled.
•Power ON, No racking operation: An inbuilt
Smart racking-shutter ensures that the ACB is
racked-in/out only in 'OFF-state'.
•One signal, One closure: An inbuilt Electrical and
Mechanical Anti-pumping System cancels the
persistent closi ng signal after successful ACB
closure.
•No unauthorised setting changes: An innovative
Password Protection feature ensures that only
authorised perso nnel can change the release
settings.

Adopt technological brilliance.

Adopt technological brilliance.
OMEGA ACBs are loaded with superior technology,
across three frame sizes for the entire current range
from 400A to 6300A. These features, including
systems for communication, control and protection
(Matrix), make these ACBs a dream to use.
•View a snapshot of all parameters and symptoms
through a user-friendly, state-of-the-art O-LED
Display.
• Control the system parameters of vast installations
easily, with a special Smart-card feature and
user–friendly Touch-Screen Display.
• Manage energy consumption better by monitoring
various energy parameters such as phase
components, power factors, energy and maximum
demand.
• Communicate between system elements wirelessly
and stay informed at all times through mobile alerts.
• Add and remove Arc-chutes and various Volt-
metric releases easily, without the need for tools.
• Upgrade systems for safety, protection, control
and monitoring with a wide range of accessories
and safety interlocks for versatile applications.
• Enjoy the benefit of total system compliance with
all the relevant quality, safety and environmental
standards.
