Medium Voltage Switchgear | Metal Enclosed Breaker | Eaton's metal-enclosed breaker (MEB) switchgear consists of a single high-drawout vacuum circuit breaker (Type VCP-W) in a metal-enclosed cabinet. When deployed as primary protection for a single-ended substation, the MEB can eliminate the need for a secondary main circuit breaker. It can also be applied as the primary main device and integrated with fused or unfused feeder switches in Eaton ...
