Description
The Schneider Electric (Square D) 9013FHG2J27M1XZ22 Pressure Switch is used to regulate, and protect the air compressor units in HVAC systems. It works by sensing pressure changes through a diaphragm mechanism, and automatically opening or closing its electrical contacts when pressure reaches the preset limits, typically 40100 PSI, with differential control. It ensures the compressor starts, and stops at the correct pressure range, preventing over-pressurization or dry running. It is used in air compressors, and pneumatic systems as reliable automatic control, improved equipment safety and reduced maintenance needs, helping ensure stable, and efficient operation in systems.
