Variable electrical power supply auto-transformer
4AM5272
Siemens Energy
There are two versions available:
PH in 4 V/WE second Version with higher saturation factor (mainly for the busbar differential protection).
PH 2 in 2 V/WE with double thermal withstand capability, e.g. when connecting to wide-range current transformer (continuous rating 2 x IN Greater overcurrent factor because of higher voltages).
