General Topology, chapter III, § 7. Inverse limits of topological groups and rings

Suppose that GG is Hausdorff, the HαH_\alpha are compact and that (AP) is satisfied. If CαC_\alpha is the identity component of Gα=G/HαG_\alpha = G/H_\alpha, then the identity component CC of GG can be identified with lim←⁡Cα\varprojlim C_\alpha, and we have fα(C)=Cαf_\alpha(C) = C_\alpha.

The proposition is a consequence of the following lemma:

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
