❓ FAQ – Siemens 3RW4755-6SB40

According to the Siemens description, it is the 230 V control unit for 3RW4055 soft starters in size S6, such as the 3RW4055-6BB34.

We recommend checking the full part number of the installed soft starter and the control voltage of the cabinet, and noting the settings so they can be transferred to the new unit. Before shipping, E-Repair checks the compatibility of the spare part.
