Description
The Trane LNK00549 Interlock Mechanical Contactor is a mechanical interlock part used with LC1 series contactors to ensure coordinated switching between linked contactor units. In HVAC systems, it is applied in control and power circuits where multiple contactors must operate in a controlled sequence, connected loads that could cause electrical conflicts. The interlock physically ties the contactor mechanisms together so their movement is synchronized according to the control signal from the system board. It is typically mounted within electrical control panels of air handling or condensing equipment and supports safe switching coordination.
