It mounts between a pair of LC1E200 or LC1E250 contactors, ensuring that only one can be energized at a time — critical for reversing drives or dual-source transfer schemes where a cross-connection would create a phase-to-phase fault.
This is a 3-pole mechanical interlock accessory. It clips onto the front faces of two Easy TeSys LC1E200 or LC1E250 contactors, linking their armatures so that when one contactor pulls in, the other is mechanically blocked from closing. No wiring changes needed — the interlock sits between the contactors and occupies no additional DIN-rail space beyond the two contactors' own footprint.
