Schneider Electric LA9FJ970 Mechanical Interlock

LA9FJ970 is Schneider Electric’s TeSys F mechanical interlock for two horizontal contactors. This double interlock uses two mechanical links and three power connection bars to physically couple a pair of TeSys F contactors mounted side by side, ensuring coordinated operation in a 2-contactor horizontal arrangement. It is designed for horizontal mounting and is commonly paired with TeSys F contactors such as LC1F-series in a two‑contactor configuration; when wiring two horizontal units, the LA9FJ976 kit of three power connectors can be used to complete the installation. Part of the TeSys F accessory family, the LA9FJ970 provides a dedicated interlock solution that helps prevent conflicting actuation between the two linked contactors.
