Vertical to Horizontal conversion vacuum replacement circuit breakers
With Eaton's VHC-Series+ medium-voltage conversion, GE Magne-BlastTM vertical lift circuit breakers are converted to horizontal draw-out. This reversible conversion involves no cutting or drilling of the original cell structure and does not violate the original metal-clad integrity.
Longer life
10-year or 10,000-operation scheduled maintenance intervals
Improved reliability
Lift mechanism operation
Increased safety
Horizontal drawout, designed and tested to IEEE Std C37.59 ™ 2018. Elimination of arc chutes that may contain asbestos
Converted vacuum circuit breaker provides increased mechanical endurance and short circuit capability
10-year or 10,000 operation scheduled maintenance intervals, whichever comes first
Fully tested to C37.59 and C37.09 for k=1 and k>1 rating structures
Ideal option as part of an overall switchgear modernization and upgrade strategy
Conversions — which are reversible and are completed by Eaton in a de-energized vertical structure in less than 45 minutes
Superior lubrication significantly reduces maintenance requirements
Reduced spare parts costs as control components are compatible with Eaton's original VR-Series and VCP-W circuit breakers
Sure-Close technology guarantees circuit breaker won’t stall during closing and prevents damage to the existing cell MOC components
Fully tested to C37.59 and C37.09 for k=1 and k>1 rating structures
Standard 3 year warranty

Tested for long life
Fully tested to C37.59 and C37.09 for k=1 and k>1 ratings, the converted vacuum circuit breakers significantly reduce scheduled maintenance and require no lubrication or adjustments for 10 years or 10,000 operations.
Eaton offers a process to repair and prevent cracks from leaking pitch-like material in older vertical cell primary contacts. Depending on service conditions and maintenance, this extends the useful life of GE Magne-Blast cell structure primary conductors for up to 30 years.
