Low Pressure Cutout Switch Definition

Only leaking air conditioning systems have low refrigerant levels.

Low pressure cutout switch definition.

The low pressure shut off switches are available with low pressure cut off point of approximately 8 to 10 lbs. 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. Requires wire harness 21 028 sold separately. Refrigerant does not wear out or evaporate.

This protects the compressor from damage. The switch arm can be pressed and the cut out reset after the cause of the over pressure has been found and rectified. An automotive air conditioner s pressure switch cycles the vehicle s compressor on and off when the refrigerant pressure falls below an acceptable level.

Mounted on high pressure side of compressor. 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. Allows compressor to resume when pressure rises above set point. Low pressure switch lps installs on the inlet side of the booster pump and will shut off the pump if the feed water is interrupted.

To control box temperature with a low pressure control the system must use a thermostatic expansion valve non bleed type. Mounted on low pressure side of compressor. Low pressure cutoff switch technical details pressure range 20 to 65 psi. By cycling the compressor in response to the suction low side pressure box temperature can be controlled.
