Like all of our circuit breakers, the core components were taken from our other circuit breakers, disconnectors and GIS product family in line with our proven modular design. The Disconnecting Circuit Breakers are type-tested according to class M2 and C2 of IEC 62271-108, a specific standard for combined switching devices.
The Disconnecting Circuit Breaker for 145 kV has a three-pole operating mechanism with a common base (FG), and a single-pole operating mechanism on separate bases (FI) for 420 kV.
