Parallel and series connection of 3-pole contactors: â ¢ To obtain a star point (3 parallel-connected poles) â ¢ To connect poles in parallel and thus increase the AC load passing through the flow path made up of the parallel-connected poles: LP, LY, LH, LF, LG. The relevant cable cross-sectional area may limit the maximum permissible current. Consult information in table below â ¢ To connect poles in series and thus increase the DC voltage controlled by the poles: LP, LY (only LY16-4 and LY38-4 secable strips).
