Schneider Electric LA9D11502 Pushbutton Switch

LA9D11502 is a mechanical and electrical interlock accessory for TeSys D reversing and changeover contactor pairs, designed to lock two LC1D115-D150 units so they cannot energize simultaneously in 3P or 4P configurations, reducing the risk of misoperation in sequence-critical circuits. Used with the TeSys D LC1D115 and LC1D150 contactors, this interlock provides a dual safeguard—mechanical interlock integrated with electrical interlock circuitry—ensuring that only one contactor can energize at a time for interlocked reversing or changeover applications in industrial control panels. Weighing 0.29 kg, the LA9D11502 supports 3P and 4P configurations, is RoHS and REACH compliant, and is offered in the 115-150 V variant; Schneider Electric marks the device as Green Premium, and notes that the product is scheduled to be discontinued on December 31, 2026, with ongoing service and spare parts available through authorized channels until end of life.
