It mounts in a 3-vertical configuration and is designed to interlock specific combinations of TeSys F contactors: bottom-position LC1F115 through LC1F150 or CR1F150 3P/4P, middle-position LC1F185 through LC1F225 or CR1F185 3P/4P, and top-position LC1F630, LC1F800 3P, or CR1F630 3P/4P.
Integration Notes
The interlock is a purely mechanical device — no wiring or coil connections. It physically blocks the armature of one contactor when the other is engaged, so the panel builder mounts it between the two contactors on the DIN rail or mounting plate, respecting the vertical orientation. Verify the contactor frame sizes against the compatibility list: the interlock spans a wide range from LC1F115 up to LC1F800, but the position (bottom, middle, top) is fixed per the contactor rating, so the physical layout in the enclosure must match.
