Disconnecting Switches
Wabtec´s disconnecting switches are designed for roof-mounted integration into the pantograph structure or on-board installation. The space- and weight-saving devices protect by earthing function 1,5 kV and 3 kV circuits during operation under AC overhead lines.
Compliant with IEC 60077, EN50388, EN45545-2 and NFPA130
