### No-load changeover switch PPAD24

##### No-load Changeover Switch PPAD24

##### No-load changeover switches change the path of the current once converted to reach components in the traction convertor of multisystem vehicles powered by 3kV DC.

##### Achieving both performance and compactness, defying the norm, PPAD24 is our latest development of no-load changeover switch for locomotives, XMUs, high-speed, tramways. Its special design allows high configuration of positions in the circuit for reduced number of switches needed in the system.
