Benefits

Preventive Maintenance creates value over the long-term by

• Providing the best management of maintenance costs, in

particular:– Less expensive direct costs of maintenance, by reducing

the charges due to urgent situations–  Less expensive indirect costs of the installation shut-down,

taking advantage of scheduled stops.

• Ensuring better efficiency and reliability of the equipment

• Extending the contactor’s life

• Guaranteeing the safety of the installation for longer time.

Preventive maintenance program

ABB has designed its maintenance schedule for all contactor

families, based on its technical knowledge of the products and

on its 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 contactors, signalling

the need for replacement of excessively worn out components,

where available, or suggest alternative solutions for bringing them up to date

• Increase the life cycle of the installation, proposing proactive

maintenance and replacing obsolete components.
