Description
The Johnson Controls P70CA-400 is a single pole single throw, pressure control switch for HVAC systems. It operates through pressure variation between 200 to 610 PSI, which perfectly suits it in the regulation of pressure in refrigeration and air conditioning systems. It has a capillary length of 36″ which enables it to effectively transfer pressure signals to enable proper system control. This control switch is frequently fitted on HVAC equipment to control high-pressure scenarios to prevent impairment of the equipment parts by high pressure. This is achieved by allowing the circuit to open when the pressure exceeds the set limit hence preventing system failures and enhancing operating reliability.
