Rheem-Ruud PD476632 Limit Switch Normally Closed Non-Resettable 100°F Cl 140°F Op L140-40 120/230V SPST

The Rheem-Ruud PD476632 Limit Switch is a crucialsafety device in the HVAC system which ensures the correct temperature. Located within the operating voltage of 120/230V AC, this is a non adjustable, non manual switch that has normally closed contact arrangement and single pole single throw configuration. When temperatures go high above the safety level it is designed to switch circuit saw and interrupt current flow. This is intended to shut at 100°F and open at 140°F of temperature. This helps to prevent heating and probably damaging the system when the need to pause it occurs such as during compressing the refrigerant. It is compact in size and easy to integrate to a number of heating and cooling applications.
