General Information

EKOSinerji SF6 Circuit Breaker are one of the equipment of medium voltage air insulated switchgears. Circuit breaker mechanism is filled with SF6 gas which is 5 times heavier than the air and has 3 times higher breakdown strength. There is a wide range of application field due to the properties of SF6 Gas. EKOSinerji SF6 Circuit Breaker’s type test are completed in accordance with IEC 62271-100 standard, manufactured at 36kV rated voltage. SF6 Circuit Breaker are also widely used due to being cost effective solutions.

Key Features:

  • Gas pressure indicator for each pole
  • Cost-effective design
  • Fixed switchgear, left MV connection, side operating mechanism.
