If you don’t want to create a dedicated function, you can use successive CROSS APPLYs:

SELECT
    T.s,
    FirstSpace.i,
    SecondSpace.j,
    ThirdSpace.k,
    CASE
        When ThirdSpace.k > 0 THEN LEFT(T.s, Thirdspace.k - 1)
        ELSE T.S
    END AS Phrase
FROM t
    CROSS APPLY (SELECT CHARINDEX(' ', T.s, 1)) AS FirstSpace(i)
    CROSS APPLY (SELECT CHARINDEX(' ', T.S, FirstSpace.i + 1)) AS SecondSpace(j)
    CROSS APPLY (SELECT CHARINDEX(' ', T.s, SecondSpace.j + 1)) AS ThirdSpace(k)

gives you the results you need:

|                   s                    | i | j | k  | phrase           |
|----------------------------------------|---|---|----|------------------|
| ATV BDSG 232 Continue with other words | 4 | 9 | 13 | ATV BDSG 232     |
