Vacuum Circuit Breaker Novas | Eaton's Cooper Power Systems

Product: NOVAs
Manufacture: Eaton's Cooper Power Systems
Origin: China
 Description: Solid insulation, vacuum interrupter
Integrated 3 voltage sensors for the source side: Operates in radial distribution networks
Integrated 6 voltage sensors for both sides: Operates in ring distribution networks
Suitable for operation in DAS and SCADA automated grids.
NOVAs (when the overcurrent protection mode is disabled) are used as a replacement for SF6 load break switches (LBS SF6): flexible in operation.
Type test:  KEMA lab/STL

- Application: Overcurrent protection on the medium voltage power grid
