| mechanical switching device capable of making, carrying and breaking currents in normal circuit conditions and, when specified, in given operating overload conditions. In addition, it is able to carry, for a specified time, currents under specified abnormal circuit conditions, such as short-circuit conditions. Moreover, it complies with the requirements for a disconnector. |
Note 1 to entry: Switch-disconnectors provide a load break isolation function. In this Technical Specification these switches will be identified on warning signs and labels as “Isolators” for simplicity in interpretation by the public.
