3RK1903-0AL10 is an ET 200S terminal module for high-feature reversing starters without incoming power-bus connection.
Siemens 3RK1903-0AL10 is the ET 200S TM-RS130-S31 terminal module for RS1e-x high-feature reversing starters. This S31 variant provides power-bus throughfeed and motor connection without an incoming power-bus connection.
The 130 mm terminal module uses screw-type terminals, supports prewiring and passes the AUX1 cable through without terminals. Procurement must confirm the reversing-starter type, S31/S32 power-bus role, PE/N accessories and ET 200S station arrangement.
