You want lower operating costs.

Less downtime. Better

communications. You want to

work with fewer parts. In less

space. With more sophisticated

capabilities. But easier operation.

You need the freedom to make

last-minute changes. Or take

advantage of quick-ship

opportunities. And you want

it all with the assurance of

fit-and-forget reliability.

modularity

This changes everything.


It’s a complicated request. So you turn to a simple concept.

The tangram. An ancient Chinese game in which a few simple

components provide endless possibilities. You take this concept of

tangramlike modularity and apply it to a new breed of breakers.

Suddenly you have unlimited possibilities with steadfast reliability.

It’s called the WL Circuit Breaker.

And it changes everything.


Reconfigure it in minutes. Rely on it for years.

Our new WL Circuit Breaker can change

as quickly as your specifications. Using

a minimal number of parts, you can

configure and reconfigure it

for virtually any application.

The only thing that doesn’t change

is its exceptional reliability.

Competitive advantages.

Pull-apart, front-mounted terminal blocks for easy access with dedicated internal wiring points

Reliable -- This highly engineered

reliable design offers increased

operations and the Extended

Instantaneous Protection (Patent Pending)

function allowing 100 percent of the full

withstand rating of the frame and still

providing the ability of the breaker to be

applied up to the maximum Interrupting

Rating. Highly accurate internal

Rogowski CTs allow for precision

protection and metering–– saving

money on downtime and field service

and increasing customer satisfaction.

Compact -- The compact size and

modular configurations save real estate,

offering the smallest gear footprint

without energy-wasting heat sinks.

Easy to Use -- The ease of use––from

integrated racking handles; pull-apart,

front-mounted terminal blocks; and simple

selection and application tools–– reduces

installation time and errors, adds flexibility

and minimizes training.


Modular and Flexible -- The UL 489

and ANSI (UL 1066) versions share

dimensions and components. The

modularity and flexibility of front--

mounted common plug-in accessories,

common draw-out guide frames and

field-upgradable and interchangeable

trip units reduce inventory, allow for

last-minute adaptations, support

quick-ship opportunities, forgive

changes and support the most

cost-effective configuration.

System Solution -- The system

solution offers monitoring and control

through Internet, MODBUS or PROFIBUS

communications, supports energy

management through advanced

metering and quality analysis, allows

cellular alarm paging to maintenance

personnel and offers complete ratings

and accessories––meeting every need

with one design.

Safety -- Safety-related features such

as a visible ready-to-close indicator,

customizable interlocking and

mechanical trip indication offer

peace of mind.

It’s from Siemens, the undisputed global

technology leader with the highest

insulated-case circuit breaker endurance,

short-time and close-and-latch ratings

in the industry.

This is not a test.

reliabilityAccessories and trip unitsare easily mounted at thefront of the breaker, andeach one fits all frames.

The front-panel, ready-to-close visual indicator confirms several breaker conditions are met before closing.


Easy to use. Easy to choose.

With so many options and so much

flexibility, the WL is the obvious choice

for virtually any application. It supports

systems from 200A to 5000A and

reflects our conviction that no matter

how sophisticated a solution may be,

it still must be easy to use. Easy to

install. And easy to maintain.

Even something as simple as providing

a single, easy-to-read assembled catalog

number can take a lot of hassle out of

ordering new products. It’s our attention

to this kind of detail that makes the WL

such a great breaker to work with.

If a product is known for its reliability,

shouldn’t the support behind it be

just as reliable?

The WL is there when you need it.

So are we. With a reliable sales and

support network that ensures fast

customer delivery times and

quick-ship opportunities.

easy planning


The more demanding

your application, the more

you need this breaker.

Difficult conditions. Tight spaces.

Changing specifications. High standards

for critical systems. The WL was made

for them. And that’s welcome news in

demanding industries.

Compact size for Panelboard and

Switchboard Builders.

Its small footprint and easy operation

make the WL unique. Based on a typical

bill of materials, switchgear with

WL Circuit Breakers uses up to 48 percent

less floor space than other major brands.

Reliability and accuracy for

Engine Generator Manufacturers.

The rugged reliability of the WL ensures

long life. The electronic trip unit tracks

and communicates potential life

expectancy based on contact wear.

A ready-to-close indicator checks system

status to ensure breaker readiness at

a critical time.

Durable construction for Marine and

Petrochemical Equipment Makers.

Designed to last, the attention to detail

even extends to parts such as cover

screws with permanent inserts, instead of

self-tapping bolts, which can be stripped.

The ideal system solution for

Electrical Consultants.

You get multiple-protocol capability

without external breaker hardware.

Not only can the breaker be controlled

remotely, but it can also alert

maintenance personnel via cell

or pager alarms.

State-of-the-art communication

Diagnosis also possible via the Internet

Power Management

Communication is everything.

The WL always keeps watch and always

keeps in touch. It can monitor a variety

of breaker, switch, meter, relay and

motor control functions in your

distribution system––continually

checking for power quality issues

and reporting back to you.

As a result, you can manage the true

energy costs of any process in real time

today… and can plan for expansion and

preventive maintenance tomorrow.

Outages and potential outages are

diagnosed instantly. And, if a serious

event occurs, the WL can even phone

maintenance personnel to alert them,

using cellular paging alarms.

Keep costs low while keeping your

options open.

The metering and monitoring

components that make all this possible

can be ordered separately. These

affordable upgrades require minimal

wiring. They’re just another way that

the WL keeps costs low while keeping

your options open.

Cost-effective entry into

communication.

The standard knob-based ETU745 and

ETU748 trip units offer all options for

future retrofit applications (communication,

display, ground fault protection) and are

equipped with an integrated CubicleBus.

These trip units are priced only slightly

above the base model ETU725 and

the ETU727.

The ETU755 and ETU776 trip units

feature a remote-only interface or

a keypad and backlit graphical

display version respectively.

Cost advantages by modularity.

Metering Function PLUS with triggerable

waveform and harmonic analysis,

COM 16 MODBUS module,

COM 15 PROFIBUS module and all

CubicleBUS I/O modules can be ordered

separately. This allows maximum

flexibility and cost saving.

Minimal wiring effort

if upgraded later.

Any communication option, I/O

or metering function is available

factory installed but can also be

upgraded easily at a later stage.

system solutions


Interrogate or set up parameters of the

WL using MODBUS, PROFIBUS,

Ethernet or the World Wide Web.

The advanced metering, quality,

diagnostics and relaying capabilities of

these highly configurable trip units can

be communicated through MODBUS or

PROFIBUS. You can also operate and

monitor the breakers remotely using

WinPM.Net supervisory software and

BDA Plus, our unique, direct Internet

connection, for paramaterization,

operation and monitoring via the

World Wide Web.

Exclusive features that fit you better.

Dynamic Arc-Flash Sentry

(Patent Pending) -- A unique feature

of the WL trip unit allows the

system designer to achieve lower

levels of arc-flash energy and

delayed tripping for selective trip

coordination purposes.

Dynamic Arc-Flash Sentry (DAS)

employs the dual protective

setting capability of the 755 and

776 trip units, coupled with the

ability to easily switch to a lower

arc-flash parameter set. A

normal operation parameter set

can be optimized for selective

trip coordination while the

second set is optimized for

lowest arc-flash energy levels.

The dynamic action comes

from the ability to switch from

the normal operation set to the

arc-flash limiting set based on

the presence of personnel as

they approach the flash

protection boundary. A wide

variety of switching methods

may be used based on the needs

of a particular facility. The

capabilities range from fully

automatic switching using

appropriate occupancy sensors

to manual switching via

a key operation.

Extended Instantaneous

Protection(Patent Pending) --

Extended Instantaneous

Protection (EIP), another unique

feature of the WL trip unit,

allows the system designer to

achieve full selective trip

coordination up to the withstand

rating of the frame while also

allowing application of the

breaker up to the interrupting

rating of the frame. The typical

power circuit breaker with an

“LS” trip unit can only be applied

up to its withstand rating,

commonly 85kA or less. For

application on systems with

levels of available fault current

above the withstand rating, the

“LS” power circuit breaker must

employ an instantaneous

override. This instantaneous

override is set at as much as 20%

below the withstand level and

can seriously compromise

selective trip coordination with

downstream breakers. The WL,

equipped with EIP, overcomes

these limitations by providing

full withstand capability and full

coordination, with a minus 0%

tolerance at 85kA on Frame

Size II and 100kA on Size III.

Above fault currents of 20%

higher than the withstand

rating, the EIP function will trip

the breaker instantly to protect

the frame and the system from

these extremely high currents,

150kA on Frame Size III.


The WL Circuit Breaker.

The breaker that fits virtually

every application. And any

requirement. No other product

on the market today offers more

flexibility or greater reliability.

It really is the perfect fit.

You just found the perfect fit.

Now all you have to do is

follow through.
