This particular model is a 2-15 PSI Open Low Snap-Acting pressuretrol, which operates electrical circuit when the system pressure is below the set low pressure range. It is of snap-acting type where the switch is suddenly and immediately either open or closed. This pressuretrol is widely used in different HVAC system applications such as air compressor, refrigeration systems and industrial process control systems. Its main application is to prevent damage due to low pressure conditions, for example, liquid slugging in compressors.
