Eaton's Bussmann® series NH horizontal fuse switch disconnectors are specifically designed to be used with NH fuse links. All energised metal parts are fully protected against accidental contact. These are manually operated switches and the making and breaking is dependent on the speed of the operation. The EBV range is provided complete with the clamps (i.e. screws/V-terminals/2V-terminals) and cable for shrouds for cable termination.
