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.

L&T Electrical & Automation (E&A) -The bedrock of stability.

Change course quickly.

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

Match performance with prudence.

6

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.

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.

OMEGA ACBs allow you to:
