Ashcroft 400Q1836330 Pressure Switch 30 PSI B428T XFM

The Ashcroft 400Q1836330 Pressure Switch is a pressure control and indication part for HVAC system applications which is set to operate at 30 PSI. This kind of pressure switch works by making or breaking an electric circuit depending on the pressure felt, so that systems such as air conditioning and refrigeration run properly and without risking harm. It also protects the compressor by tripping the system when pressure reduces, which also increases equipment durability. Some of the advantages of this switch are higher energy conservation, lower operational costs, and increased safety to make it a essential part of a system to achieve maximum performance on HVAC systems.
