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.
