Terminal connecting strips and shorting bars

1SBC100024V0014 Description

– To obtain a star point (3 parallel-connected poles)
LY16-4 Parallel and series connection of 3-pole contactors:
– 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
1SFC101088V0001 and LY38-4 secable strips).
– To connect poles in series and thus increase the DC voltage controlled by the poles: LP, LY (only LY16-4
