MDS1-1200/1500 high-voltage cut-off earthing switch
   Nominal voltage:                       DC 1500V
   Control voltage:                        DC 110V(auxiliary contact)
   Rated current:                         1200A
   Short-circuit current (non switching): 30kA,20ms
   Creepage distance:                      ≥40mm
   electric clearance:                    ≥20mm
 
   MDS1-1200/1500 metro high-voltage cut-off earthing switch is mainly used for connecting circuit formed by traction inverter and auxiliary inverter to coil-in DC power supply, and used for enabling high-voltage filter capacitor to discharge for safe routine maintenance in workshop. Under usual working condition, filter capacitor will discharge through such switch in accordance with train control means.
