The maintenance interval of a FAME-enhanced VCP-W mechanism is 10,000 operations or 10 years, whichever comes first, if applied per usual service conditions as defined in IEEE Std C37.04 ™ 1999. This applies to all distribution-class circuit breakers rated up to 2000A continuous current, 41 kA max short circuit, 15 kV max voltage. FAME features a standard 3 year warranty. (2 years if applied as a motor starter)
