Bard 8402-144BX Switch R-22 simplifying system architecture and enhancingThe Bard 8402 144BX Switch is an OEM high limit safety control engineered for precise thermal monitoring in Bard HVAC systems. This L150 30 exposed face auto reset switch is calibrated to open the electrical circuit when the supply air temperature reaches 150F, effectively shutting down heating elements to prevent heat exchanger damage or cabinet overheating. Once the internal temperature drops by 30F (reclosing at approximately 120F), the automatic
