MEPPI introduces a next generation circuit breaker with significant new features

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
