Product Features

Meiden’s dead tank vacuum circuit breakers are the optimal switching equipment for the green grid. These breakers utilize dry air as an insulating medium in place of SF6, a potent greenhouse gas. Sustainably designed and emissions-free, these high-performance VCBs are capable of approximately five times more mechanical operations and four times more interruptions of rated breaking current than standard gas-insulated circuit breakers.

With the founding of Meiden America Switchgear (MAS) in Greenville, South Carolina, Meiden’s DT VCB products will now be assembled in the United States!
