The LA9FH4G4G is a mechanical interlock accessory from the TeSys F range, designed to physically prevent two contactors from closing simultaneously. It mounts in a 3-vertical configuration, linking contactors stacked above one another. This interlock is intended for use with specific TeSys F contactors and reversing contactors: bottom and middle positions accept LC1F185 through LC1F225 3P or 4P, or CR1F185 3P or 4P; the top position accepts LC1F265 through LC1F330 3P or 4P, or CR1F265 3P or 4P.
