IEC outdoor switch disconnectors ONI

ONI switches disconnect unloaded electrical circuits in outdoor AC substations, rated voltage 24 and 36 kV, rated current 400-800 A.

The ONI one phase disconnectors, available also as a three phase device (ONIII), are designed for closing and opening not loaded electrical circuits in outdoor AC substations. In open position disconnectors form visible and safe isolating distance which cuts circuit from voltage on the outflow side.

Integrated earth switches are intended for shorting and earthing previously disconnected electrical network.
