EN disconnector  
mechanical switching device which provides, in the open position, an isolating distance in accordance with specified requirements.

Note1 to entry: A disconnector is capable of opening and closing a circuit when either negligible current is broken or made, or when no significant change in the voltage across the terminals of each of the poles of the disconnector occurs. It is also capable of carrying currents under normal circuit conditions and carrying currents for a specified time under abnormal conditions such as those of short circuit. Refer also to switch-disconnector.
