ABB Stotz-Kontakt 1SBN071303T1000 LY16-4 star bridge

Parallel and series connection of 3-pole contactors:, - For a star point (3 poles connected in parallel), - To connect poles in parallel and thus increase the AC load that flows through the current path from the parallel connected poles LP and LY., The respective conductor cross-section can limit the maximum permissible current. The table below provides further information., - To connect poles in series and thus increase the DC load that can be switched by the poles LP and LY (only LY16-4 and LY38-4 can be cut to length).
