Preventive Maintenance – PMP
MaintenaceAgenda
The customer has to understand that performing a correct and periodic maintenance is essential to:
- Reduce the total managing costs - Use the resources according to needs - Standard, directives and laws
Maintenace theoryAim: Mind-changing
‘’Any maintenace activity is a cost’’
Common Myths• Circuit-breakers are
maintenance free
• Circuit-breakers Preventive Maintenance is just dusting down
• The circuit-breaker is always in closed position so it doesn’t require any maintenance
Maintenace TheoryMyths & Facts
Proven Facts• Circuit-breakers are protecting
devices: periodical check on functionality and maintenance are required to guarantee the original performance level
• Circuit-breakers Preventive Maintenance consists in checking the integrity of all the electrical and mechanical components to limit aging on components and prevent faults
• All the mechanical and electrical components need maintenance (as lubrication) in particular in harsh environments.

Maintenace TheoryWhy maintaining
Direct costs
Indirect costs
Direct Costs• Maintenance: personnel,
materials
Indirect/induced Costs: • Higher risk in Health & Safety• Reduction of products lifetime• Management of urgency• Poor quality• Energy consumption• Environmental impact• Resource availabilities• Inefficiency in personnel• Insurance policies• Production Losses• Losses in market share
Based on ABB experience, it is possible to define average component lifetimes
BUT
a SITE SURVEY is always recommended.
It is performed by a circuit breaker specialist, who inspects the products, on-site spares, environment, fault history, etc...
The result of a site survey is a proposal of short and long term maintenance actions

ABB SACE Maintenance PortfolioPreventive and Scheduled Maintenance - PMP
Reduce the risk of failure and working deterioration of the low voltage circuit-breakers installed in the plantIt is structured in a cycle of three maintenance interventions:• 1st-2nd intervention: Ordinary Maintenance
Maintaining the original integrity of the product:• Maintaining or restoring the efficiency of the products• Containing the normal deterioration of use• Guaranteeing the useful life of the product• Facing accidental events
• 3rd intervention: Extraordinary maintenance Extend the useful life and/or improve:• efficiency • reliability• productivity• facility of maintenance and inspection
All interventions are carried out by chief skilled technicians
Ordinary Maintenance Extraordinary Maintenance
ABB SACE Maintenance PortfolioPreventive and Scheduled Maintenance for Emax
Provides systematic and functional means of maintaining a specific breaker
Each ABB ACB series has its own schedule which is based on years of experience and knowledge of manufacturing and maintaining circuit breakers
Circuit breaker efficiency/reliability preservation Guaranteeing the plant & people safety Probability of unwanted shut-downs reduction Providing the best management of maintenance costs
Direct costs: Direct maintenance : technicians, spare parts… Indirect costs: non-production, accident, failure, maintenace
management, … Customer support during all product life phases ABB professional competence guaranted: Preventive maintenance to increase: performances, reliability,
availability of circuit breakers and systems
ABB SACE Maintenance PortfolioPMP: Benefits
ABB SACE Maintenance PortfolioSummary
Maintenance management maximizes the value of circuit breakers and customers investments.
All the circuit breakers have aging and wearing in components: a proper preventive maintenance is required
Maintenance schedule specifies the recommended maintenance actions for preventive maintenance
