Modine 5h0735910009 0.99 Inch Wc Spst Pressure Switch

The Modine 5h0735910009 is a small but essential safety switch for HVAC systems, designed primarily for furnaces and air conditioners. It functions as a watchful guardian by monitoring the air pressure inside the system silently as a single-pole, single-throw pressure switch. When the switch senses a predetermined pressure of 0.99 inches of water column, it activates or deactivates vital electrical parts like compressors and fans. Imagine an instance when airflow is impeded by a blocked air filter. When the Modine switch detects a pressure drop, it quickly cuts the power to avoid overheating and possible motor damage. On the other hand, when pressure levels return to normal, it can also start the equipment's activation. This clever switch is useful for a variety of HVAC equipment, including ductwork, air handlers, and furnaces.
