All switch-disconnectors ComPact INS/INV are suitable for disconnection as defined in the IEC 60947-1 and 3 standards. The mechanical design of the ComPact switches ensures that the position of the actuator always reflects the position of the main switch. the disconnecting position corresponds to the O (OFF) position. The actuated drive cannot indicate the OFF position when the switch is open. Locking in the OFF position is not possible when the switch is open.
