Intended readership

This manual refers to two user proﬁles, as deﬁned by standard IEC 60050:

• Expert person, in the electrical area (IEV 195-04-01): Person with sufficient training and

experience to allow him/her to perceive the risks and to avoid the hazards potentially

created by electricity.

• Instructed person, in the electrical area (IEV 195-04-02): person adequately informed or

supervised by electrotechnical personnel to allow them to perceive the risks and to avoid

the hazards potentially created by electricity.

NOTE: This manual specifically indicates what operations can be performed by people

trained in the field of electricity. All the remaining operations described in the handbook

must be performed by expert persons, in the electrical area. ABB declines all liability

for damage to persons or property caused by failure to comply with the instructions

in this document.

Instructions

HAZARD! RISK OF ELECTRIC SHOCK! Unplug or disconnect any power supply,

to avoid any potential risk of shock during assembly, installation, maintenance

or removal of the circuit-breaker from the service.

WARNING! Some operations must be performed when the circuit-breaker is

energized. In this case it is necessary to comply with all safety regulations.

Warnings

HAZARD

ACCIDENTAL CONTACT WITH LIVE

POINTS CAN CAUSE SHOCK, BURNS AND

RESULT IN DEATH.

Do not try to use the product in any way, before

having read this instruction manual

Figure 2

The following warnings must be respected:

• READ THE INSTRUCTIONS CAREFULLY BEFORE TRYING TO INSTALL, OPERATE

OR REPAIR THE CIRCUIT BREAKER.

• Store these instructions along with other documents for instruction, maintenance and

installation, drawings and descriptive notes on the circuit-breaker.

• Keep these documents available during the installation, operation and maintenance of the

appliance. The use of these instructions facilitates proper maintenance.

• Install the circuit-breaker within the limits of the project described in the instruction manual

shipped with the unit. These circuit-breakers are designed to operate with values of voltage

and current within the limits of plate ratings. Do not install this equipment in systems

operating at nominal values exceeding these limits.

• Follow the safety procedures indicated by Your Company.

• Do not open any covers or doors, do not work on devices before removing power from

all circuits, and after making sure of that with a measuring instrument.

WARNING!

• detailed descriptions of standard procedures for installation, use, maintenance and

principles for safe operation are not included. It is important to note that this document

contains safety and precaution instructions, against certain methods (of installation, use and

maintenance) that could cause harm to personnel, damage devices, or make them unsafe.

• these warnings and alarms do not include all conceivable ways to make installation, use and

maintenance recommended by ABB or not, that may be made, or possible consequences

and complications of each conceivable way, nor shall ABB investigate all those ways.

• anyone using maintenance procedures or devices, recommended by ABB or not, must

check thoroughly that neither personal safety nor the safety devices are endangered by

mode of installation, use, maintenance or the instruments used. For more information,

questions or specific problems contact your nearest ABB representative.

• This manual is written for qualified personnel only and is not intended as a substitute for

a proper course, or experience about safety procedures for this device.

• the purchaser, installer or end user is responsible for ensuring that notices and safety signs

are posted and that all access points and switching devices are locked securely when the

switchgear is left unattended, even momentarily.

2 - Transport and checking on receipt

Introduction

The Emax 2 circuit-breakers, on account of their weight, require special attention during

transport and handling.

They are distributed with following packages:

• single package for fixed circuit-breaker

• two packages for withdrawable circuit-breakers (one package for the fixed part and one

for the mobile part).

The following notes regard transport, handling and storage.

Weight of the circuit-breakers

NOTE:

• weights are indicated with reference to the basic circuit-breakers including

protection release and its sensors, without terminals and without accessories.

• the weights of the ﬁxed part of withdrawable circuit-breakers refer to the version

with horizontal rear terminals.

Transport of the packaged

circuit-breaker

Consult the table "Weight of the circuit-breakers with packaging" before proceeding with the

transport.

WARNING! Improper lifting can result in death, serious injury to persons and

damage to the equipment. Never lift a circuit-breaker and / or a fixed part

above other people.

IMPORTANT: The trained personnel in charge of handling and lifting must use

appropriate safety equipment.

Storage method

Place the packaging (circuit-breakers and / or ﬁxed parts) on a horizontal plane, not in contact

with the ﬂoor. If the circuit-breaker has been removed and reinserted in the package ensure,

prior to storage that:

• The circuit-breaker is in the open position and the springs are unloaded. See the chapter

"Description - circuit-breaker opening/closing operations" on page 15

• The circuit-breaker is protected and locked in its original packaging

WARNING! overlay up to three packages with circuit-breakers E2.2 and E4.2

and up to two packages with circuit-breakers E6.2. If the packaging has been

opened, you can stack the circuit-breakers on the condition that the package

is re-wrapped as original.

NOTE:

• the weights indicated in the table refer to the basic circuit-breakers including relays

and its sensors, without terminals and without accessories.

• the weights of the withdrawable circuit-breakers refer to the weight of the ﬁxed part

in a version with horizontal rear terminals.

Lift the fixed circuit breaker

or the moving part of a

withdrawable circuit-breaker

WARNING! Improper lifting can result in death, serious injury to persons and

damage to the equipment. Never lift a circuit-breaker and / or a fixed part

above other people.

IMPORTANT: The trained personnel in charge of handling and lifting must use

appropriate safety equipment.

To lift the circuit-breaker:

1. Raise the circuit-breaker from the base of the packaging with the aid of the lifting plates

supplied with the circuit-breaker. See Figure 15.

Figure 15

Figure 16

To raise the ﬁxed part of the circuit-breaker

1. Raise the ﬁxed part from the base of the packaging with the aid of the two hooks

supplied with the ﬁxed part. See Figure 16.

IMPORTANT: keep the lifting plates for the circuit breaker, the lifting hooks

of the fixed part and the manual of the circuit-breaker until disposal.

Description of circuit-breaker

The Emax E2.2, E4.2 and E6.2 circuit-breakers consist of a steel structure in which the

operating mechanism, the poles and the auxiliary parts are located.

Each pole, isolated from the others, contains the breaking parts and the current transformer

in its phase.

The structure of the poles differs between selective circuit-breaker or limiter.

The circuit-breaker is available in two types:

• fixed version

• withdrawable

The circuit-breaker in ﬁxed version (see Figure 17) has its own terminals for connection to the

power circuit.

The withdrawable circuit breaker consists of a mobile part (see Figure 18) and of a ﬁxed part

(see Figure 19) for connection through its own terminals to the power circuit.

The coupling between the mobile part and the ﬁxed part is via disconnection contacts mounted

on the ﬁxed part.

Manual operations for opening

and closing the circuit-breaker

The following is the sequence of steps for closing and opening the circuit-breaker:

1. Check that the circuit-breaker is open (open / closed indicator "O - OPEN"), and check

that the springs are unloaded (spring signalling device "white - DISCHARGED SPRING")

as indicated in Figure 22.

2. Loading the springs - Pull the lever [A] downwards several times until the springs loaded

signalling device [B] is “yellow - CHARGED SPRING” as indicated in Figure 23.

Figure 22

Figure 23

3. Check that the circuit-breaker is open (open/closed signalling device “O - OPEN”),

and check that the springs are loaded (springs signalling device “yellow - CHARGED

SPRING”) as indicated in Figure 24.

4. Closing - Press the closing push-button “I - Push ON” as indicated in Figure 25.

Figure 24

Figure 25

5. Check that the circuit-breaker is closed (open/closed indicator "I - CLOSED"), and

check that the springs are discharged (spring signalling device "white - DISCHARGED

SPRING" as indicated in Figure 26.

6. Opening - Press the opening push-button “O - Push OFF” as indicated in Figure 27.
