Low pressure cutout switch definition.

By cycling the compressor in response to the suction low side pressure box temperature can be controlled. Low pressure cut out to protect the compressor against low pressure in the system and to avoid the ingress of air into the system if a vacuum is generated in the lines a low pressure cut out is provided. Requires wire harness 21 028 sold separately. Switch remains closed at 5 psi or more when pressure drops below 5 psi switch will open and cut off the power to the pump.

Allows compressor to resume when pressure rises above set point.

This protects the compressor from damage. Mounted on high pressure side of compressor.

Low pressure cutout switch prevents system damage due to low pressure or low refrigerant charge by disabling a c compressor when pressure drops below reset point. The low water pressure switch attachment drops to turn off the pump when it loses its prime and the pressure drops to a specific low pressure cut off point. This type of control is most popular in small refrigerated boxes such as beer coolers. Mounted on low pressure side of compressor.

Only leaking air conditioning systems have low refrigerant levels. The switch arm can be pressed and the cut out reset after the cause of the over pressure has been found and rectified. Low pressure cutoff switch technical details pressure range 20 to 65 psi. An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level.
