fixed or draw out, as an automatic circuit breaker or without the trip unit

as a switch, Emax is always the solution able to satisfy your request.

Emax power circuit breakers. The benchmark for your solutions.

The strong point - strength.

Y ou can tell Emax power circuit breakers are solid at a glance. Built with an

extremely sturdy metal structure, they deal brilliantly with any dynamic or

thermal stresses, making each installation reliable and safe. Thanks to the

materials used, an Emax air circuit-breaker has a much longer mechanical

life compared with the other circuit breakers in its category, and during its

very long working life, only requires minimum

maintenance. As always, ABB SACE stands out for

the quality of its products, for the care and attention

it pays to all details - both constructional or

technological - to offer products to the market

which always achieves top performance.

Emax power circuit breakers stand out for

the great sturdiness of their metal structure,

which makes them unique, safe and

extremely reliable.1SDC200004F0001

The new intelligence - intelligent.

Emax power circuit breakers. The finishing line for your solutions.

Emax can be equipped with different trip

units, all with microprocessor technology.

The major novelties lie in the latest

generation PR113 release, the

improvement of the PR112 functions and,

lastly, in the PR112/PD and PR113/PD

protection and communication releases.

1SDC200005F0001

With Emax power circuit breakers you can always choose the amount of

intelligence you need. Like the PR113-A, the latest generation of trip

units for Emax, which provides a complete set of protection functions,

measurements signalling, data storage and control functions. Equipped

with a big a clear graphic display, this new trip unit is available in two

different version, wiyh or without communication capabilities. The

PR112-A releases have also been improved and new functions have been

added, like the five languages available to help the setting. And there are

not only protection functions, but also communication capabilities that

allow the breaker to be used in the most advanced automation and

control systems, using the Modbus® protocols.

All the electrical accessories are pre-wired

and thanks to the easy and safe mounting

can be installed in the field directly by the

end user.

The replacement of the current transformers

and of the trip units is simple and fast.

1SDC200006F0001

Built to be the best.

The Emax accessories are

continually enriched with highly

useful novelties, such as the

ATS010 automatic which allows

service continuity of the installa-

tions in the case of a power cut

(IEC only).

Conversion Kits are available for the circuit-breaker, in the various

different solutions for terminals and versions. Within each size, there

are common fixed parts for the draw out version circuit-breaker, for

all rated currents and breaking capacities.1SDC200008F0001

points and their position on the base of the apparatus.

Having a wide range of terminals available allows

construction of switchboards which can be placed against

the wall or of switchboards accessible from the rear with

rear connections.

Just one set of accessories

for the entire range.

Simplicity, convenience, safety and speed

are the advantages provided by the

system of accessories for Emax. The

entire Emax range has common accesso-

ries, which can be used with both direct

and alternating current. The mounting

is always carried out very conveniently

from the front, without the need for

any wiring, and with a high degree of

flexibility according to userthe customer requirements.

Compactness and modularity.

The whole series of Emax power circuit breakers has

extremely small dimensions, with same height and depth,

thereby also making easier the switchgear an switchboard

development and design and simplifying fabrication of

standardized support structures. The

extremely compact structure in steel of the

circuit breaker allows much smaller over-

all dimension for the switchgear. Just one

cover for the entire series semplified the

design and construction of the switchgear

door, having for all the frames a single

type of cutout.

Extremely simple mounting.

Installation of Emax power circuit break-

ers is greatly facilitated by the limited number of fixing
