The ComPact INS and INV switches are switch disconnectors with rotary actuator. All ComPact INS/INV switch disconnectors are suitable for disconnection as defined in the standards IEC 60947-1 and 3. The mechanical design of the ComPact switches ensures that the position of the actuator always reflects the position of the main switch.
