DIN EN 62271-108 VDE 0671-108:2006-10

This standard applies to high-voltage alternating current disconnecting circuit-breakers for operation at frequencies of 50 Hz and 60 Hz on systems having voltages of 72,5 kV and above. This standard identifies which requirements of DIN EN 60694 (VDE 0670-1000), DIN EN 62271 100 (VDE 0671-100) and DIN EN 62271 102 (VDE 0671-102) standards are applicable. It also gives the additional requirements specific to these devices. This standard covers a circuit-breaker which, when in the open position, satisfies the requirements of both a circuit-breaker and a disconnector. This standard details the requirements for a disconnecting circuit-breaker, identifying where these differ from the separate requirements of a discrete circuit-breaker and a disconnector.
