Terminal connecting strips and shorting bars

1SBC100024V0014 Parallel and series connection of 3-pole contactors:
• To obtain a star point (3 parallel-connected poles)
03
• To connect poles in parallel and thus increase the AC load passing through the flow path made
The relevant cable cross-sectional area may limit the maximum permissible current. Consult
LY16-4 up of the parallel-connected poles: LP, LY, LH, LF, LG.
information in table below
• 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).
