The Johnson Controls P100AP-12 is a reliable, encapsulated pressure control designed for direct-mount installation in HVAC and refrigeration systems. Built with an open construction design and SPST switching action, this control opens on a pressure drop — making it ideal for low-pressure safety cutout applications. With automatic reset functionality, the P100AP-12 restores operation once pressure returns to the close set point, reducing the need for manual intervention.
