1 INTRODUCTION
1.1 CONSIDERATIONS ABOUT SAFETY
1.1.1 Preliminary guidelines
Read this manual carefully before installing and operating the circuit breaker. This manual was specifically conceived
to provide the instructions of installation, operation and maintenance of ABW air circuit breakers. However, it may not
cover all the possible contingencies, variations or details which can arise during the installation, operation and
maintenance of the circuit breaker. If you have any queries, please contact WEG.
The information contained herein is generic and does not apply to special situations, as well as not exempting
the user from being responsible for executing the correct application, installation, operation and maintenance
of the circuit breaker. WEG reserves the right to make any alterations to the specifications contained herein or
execute improvements at any moment, without prior notice. If there is any conflict between the information which
is contained in this publication and the contents of designs, supplementary material, or both, the latter shall prevail.
1.1.2 Qualified professionals
Only qualified professionals can execute the installation, operation and maintenance of this equipment. These
professionals must also be trained and authorized to:
Energize, de-energize, ground and identify electrical equipment and circuits, as per the standards and
practices in force;
Use individual and collective equipment, as per the safety standards and procedures in force;
Provide first aid.
1.1.3 Alert messages
Throughout this manual there are several alert messages to call the user’s attention to potential risks or provide
additional information which clarifies o simplifies a determined procedure.
These messages are identified as follows:
DANGER!
It indicates procedures which certainly involve high risks for the user. Failure to observe this warning can lead to serious
injury or death.
ATTENTION!
It indicates procedures which involve some risk for the user. Failure to observe this warning can lead to serious injury or death.
CAUTION!
It indicates procedures which involve some risk of damage to the equipment.
Besides attentively observing the procedures described in this manual, the users must obey the following
instructions:
Always work with the circuit and equipment de-energized, even if they are test, maintenance or repair
procedures;
Use interlocking and safety devices, and check that they function naturally, without needing to be forced or
suppressed

www.weg.net
ABW - Air Circuit Breaker | 9
DANGER!
Only qualified professionals with training and experience in electrical circuits must execute the work described in this
manual. These people must also understand the risks involved in the work, and only execute it after reading all the
contents of this manual.
The correct operation of the ABW circuit breakers depends upon the appropriate handling and correct instal ation,
operation and maintenance. Neglecting the basic requirements of installation and maintenance can lead to injury to the
user and/or damage to the equipment and instal ation.
The ABW circuit breakers have features developed to prevent undue operation. However, such features do not by
themselves eliminate all and any risk. Thus, the user is responsible for recognizing the potential risks, using individual
and collective protective equipment, and for taking suitable safety measures.
Do not execute any adjustment or operate the equipment if the safety devices are not present.
Before executing the visual inspection, test or maintenance in this equipment, disconnect all the power supply circuits.
Consider the circuits to be energized until they are all really de-energized, tested, grounded and identified. Particular
attention should be paid to the electrical system where the equipment is installed, as there may be reverse power supply.
Before installing covers or closing the doors of the panel, inspect the area of the busbars to check that no tools or other
objects have been left in contact with them. Also check that there are no parts of covers or closings of the panel in
contact with or very near the busbars.
Before executing any electrical connection ensure that the circuits are de-energized and grounded.
Introducing foreign objects in the equipment can cause a short-circuit, which can result in irreparable damage, injury or
death. Short-circuits release a large quantity of energy, which leads to the quick expansion of superheated and ionized
gases. As a result, burns can occur even before preventive actions are taken. People and objects can also be thrown
several meters from the equipment.
Such foreign objects can be tools, test remains, instruments, wires, cables or other objects, conductors or not. It is also
advisable to maintains cloths and other materials a long way from the equipment.
ATTENTION!
Ensure that the screws of the terminals are tightened as per the torque recommended in this manual. The screws and
their tightening must be checked periodically, always with the circuits de-energized and grounded.
Do not install the circuit breaker in dirty places at high temperatures, with humidity, dust, corrosive gases, vibration or
lows. The non observance of this recommendation can result in the malfunctioning of the circuit breaker.
Whenever the circuit breaker is turned off by the action of the protection unit, eliminate the cause of the failure before
turning the circuit breaker on again.
Only use the circuit breaker in circuits of 50 HZ or 60 HZ, paying attention to the corresponding model of the protection unit.
CAUTION!
Receipt
Execute the visual inspection immediately after receiving the circuit breaker, and even before removing it from the
pallet. If there is any sign of damage or flaws caused by the transportation, inform the carrier and WEG directly.
Transportation
Maintain the circuit breaker attached to the pallet and transport the unit using a trolley or forklift. Observe the
following additional recommendations:
- Always maintain the pallet horizontal;
- Ensure that the load is balanced on the forks of the forklift;
- Attach the pallet to the forks so that it does not move or fall during the transportation;
- Transport the unit at a low speed, without abrupt movements, avoiding collisions with other structures, equipment
or people;
- Only raise the unit to the extent required to pass over obstacles on the floor, and never above people.
Handling / Movement
Removable hooks are supplied with each circuit breaker so that it is removed from the pallet or extraction car,
suspended by a crane. This is the only method recommended for moving the circuit breaker. Be careful not to
damage the equipment if using other methods. Further details can be found on page 22.
Other important recommendations:
- Do not put cords or cables through the suspension eyelets. Always use safety hooks with a lock;
- The suspension cables must not be less than 45º from the horizontal.
Storage
If it is necessary to store the circuit breaker before installing it, maintain it in its original packaging, in a clean, dry,
ventilated and heated place to avoid condensation. As with any other electrical equipment, protect it from dust and
humidity. Do not store the circuit breaker in an uncovered place orexposed to bad weather.
Introducing foreign objects in the equipment can cause a short-circuit, which can result in irreparable damage,
injury or death. Short-circuits release a large quantity of energy, which leads to the quick expansion of superheated
and ionized gases. As a result, burns can occur even before preventive actions are taken. People and objects can
also be thrown several meters from the equipment. Such foreign objects can be tools, test remains, instruments,
wires, cables or other objects, conductors or not. It is also advisable to maintains cloths and other materials a
long way from the equipment.
