Siemens 3RT1946-4EA2 Terminal Cover is a protective accessory for Siemens Sirius Classic box terminals, designed for size S3 installations. It is used to cover the box-terminal connections when paired with contactors, circuit breakers, and overload relays of size S3 and with the soft starter 3RW404. The part is a phased-out product, with 3RT2946-4EA2 listed as its successor. Typical applications include enclosures or cabinets where terminal terminations must be enclosed for a tidy, safe installation.
