Johnson Controls P100DA-81 High Switch R410A Manual Reset 630 SPST

The Johnson Controls P100DA-81 High-Pressure Switch is manufactured for use in HVAC systems that use R410A refrigerant. This vital part guarantees the right control over pressure conditions to protect HVAC equipment in case of emergencies. It has a maximum pressure setting to 630 PSI and comes with a manual reset function. For the safety of HVAC systems that use R410A refrigerant, it is necessary to have its protection. The switch stops system operation to avoid potential danger of overpressure whenever pressure values are at or above 630 PSI. After the cause of the pressure problem has been identified, the manual reset function requires the operator’s input to work normally again.
