ABB Preventive maintenance for Emax low voltage air circuit breakers

In order to guarantee high levels of efficiency and reliability to your electrical plant,

ABB suggests regular Preventive Maintenance on your installed air circuit breakers.

Preventive Maintenance on air circuit breakers includes testing, measurements and

maintenance, and repair or replacement activities.

These activities are based on specially designed technical plans, aimed at reducing the

probability of failure or the working deterioration of the apparatus.

ABB, a leader in the design and production of low voltage air circuit breakers,

always pays particular attention to customer satisfaction.

Thanks to its highly qualified organization, ABB Low Voltage Service provides

support to its customers during all phases of the product’s life,

from the selection to the after sales assistance.

Benefits

Preventive Maintenance creates value over the long-term by:

−Providing the best management of maintenance costs, in particular:

−  Less expensive direct costs of urgent, reactive maintenance

− Less expensive indirect costs of plant  shut-down, taking advantage of the scheduled stops

− Ensuring better efficiency and reliability of the plant

− Extending the circuit-breaker’s life

− Guaranteeing plant safety for a longer time Preventive Maintenance Program

ABB has designed maintenance schedules for all circuit breaker families,

based on technical knowledge of the products and on experience in the field.

The Preventive Maintenance Program has the following main targets:

− Check the preservation and the efficiency status of the apparatus

− Anticipate the trend  of deterioration of the circuit breakers, signalling

the need of replacement for excessively worn out components, or suggest alternative

solutions for bringing them up to date.

Provided Services

Considering the importance of the maintenance activity and the required technical know-how,

ABB guarantees professional competence and interventions performed only by skilled technicians.

After the inspection and measuring activities, ABB technicians give all the indications

related to the future maintenance needs and any possible corrective actions,

while releasing the final report according to local standards.

Maintenance Schedule

ABB created a systematic and functional Preventive Maintenance Program.

Besides the ordinary maintenance activities described in the air circuit breaker manual,

ABB proposes a maintenance intervention every three years directed to extend the product’s life.

(Extraordinary Maintenance). Service intervals shall have to be suitably assessed in case of

non-standard service and environmental conditions.
