Schneider Electric (Square D) LU9SP0 Motorstarterphasebarrier

The Schneider Electric (Square D) LU9SP0 Motor Starter Phase Barrier is an insulating component used to separate and shield conductive parts within motor starter assemblies. It supports maintaining electrical isolation between phases, reducing the short circuits in control and power circuits. It is installed inside motor control centers and panelboards used for HVAC systems, including compressors, blowers, and condenser fan motors. It supports safe operation of electromechanical switching systems by maintaining spacing within compact starter configurations, ensuring consistent performance in industrial and building automation conditions where accurate motor control is required.
