Description
The Schneider Electric (Square D) 9013FRG22J23 2-Pole Pressure Switch which monitors and controls HVAC system pressure in applications needing open low configuration between 4-45 PSI. The electromechanical operation of this switch triggers contact state changes when system pressure reaches its set high limit point which usually results in circuit opening. HVAC equipment components that use a pressure-dependent mechanisms use this switch for operation in air compressors and pumps. The system provides dependable pressure control to avoid system over-pressurization and under-pressurization which safeguards equipment while maintaining operational efficiency.
