The ABB EDF SK Auto Puffer spring drive operating mechanism circuit breakers are designed for use outdoors. This high-performance circuit breakers handle maximum breaking currents up to 31.5kA with a rated voltage up to 72.5kV.
The arc provides the energy needed to interrupt the current. This decreases the mechanical stress on the circuit breaker while increasing the reliability of the network. It is created for OLM2 and Switchsync as well as simple commissioning.
