MAINTENANCE DUTY CYCLE EXCEEDS 6,000 OPERATIONS OVER LIFE
• Aging oil circuit breakers have a declining interval between maintenance– Degrade below 33% of
installed performance
• MEPPI Vacuum circuit breakers meet and exceed 6,000 operations between maintenance– Remain consistent over life of
circuit breaker

COST AND TIME OF MAINTENANCE WILL SUBSTANTIALLY DECREASE
• Oil/gas technology– complex and expensive
maintenance procedure– 12 maintenance functions / visit
• MEPPI vacuum switchgear lifetime module– Should a maintenance issue arise, it is
simply a plug N play module

OIL BASE IS X5 MORE EXPENSIVE THAN VACUUM BASED
• Projecting TCO (total cost of ownership) for 20 legacy oil circuit breakers– $4.5m annually
• Projecting TCO for 20 replacement vacuum circuit breakers– $900k annually– 5 month payback
