The LA1-D31 is an auxiliary contact block from Schneider Electric's Telemecanique line, designed for use with contactors and starters in motor control circuits. It provides additional signal or control contacts for status feedback, interlocking, or logic extension without adding a separate contactor.
This block mounts onto compatible Telemecanique contactors and starters in the D-range. It adds auxiliary contacts for control logic or status indication without increasing the panel footprint. Verify the specific contactor model compatibility from the manufacturer's mounting guide before ordering.
