に限(かぎ)ったことではないNot limited to, Not restricted to, Not only

に限(かぎ)ったことではない is a fairly emphatic expression that, like several other grammar patterns, makes use of the う-Verb 限(かぎ)る 'to limit'. It is a combination of the case-marking particle に, the past tense of 限(かぎ)る, 限(かぎ)った, the noun こと 'thing', the conjunctive form of the auxiliary verb だ, で, the adverbial particle は, and the い-Adjective, ない. The literal translation is 'it is not something that is limited to (A)', but other common interpretations include 'not only (A), but (B)', or 'not restricted to (A), (B) too'.

This structure will be used following nouns, and tends to be reserved for fairly formal situations.

This grammar pattern often indicates that (A) is something that is not especially rare, so should not be, or does not require to be treated in any special way.
