The Siemens 3RT1946-4EA4 is a member of the 3RT1946-4EAx terminal cover series. This series has been confirmed as the terminal protection cover used for the S3 frame 3RT1.4 contactor and can be used with wiring methods such as ribbon cable connection, cable terminal and overload relay.
3RT1946-4EA4 is one of the terminal covers in the Siemens SIRIUS 3RT1946-4EAx series. The confirmed part numbers 3RT1946-4EA1 and 3RT1946-4EA2 in this series are terminal covers used for the S3 frame 3RT1.4 contactor. They are used to shield wiring terminals, preventing foreign objects or personnel from accidentally touching live contacts. The appropriate type can be selected based on the field wiring method (such as ribbon cable connection, cable terminal block, or when used with a 3RW404 soft starter or overload relay). While -4EA4 belongs to the same terminal cover series as -4EA1 and -4EA2, the exact wiring type or connection details cannot be verified individually using publicly available information. Kensun Motors recommends that customers provide information about their existing equipment so that sales personnel can assist in verifying the correct part number.
