Description
The Supco SLP0520 Low-Pressure Switch is a control component that is designed to measure refrigerant pressure in HVAC systems. It is operated to ensure a stable operation by opening at a cut-out pressure of 5 PSI and closing at a cut-in pressure of 20 PSI in order to guard against too low pressure settings. This component is a vital safety component of refrigeration and air conditioning systems. The switch is inserted into the general system to control operation of compressors and coordinate the control reactions of the low-pressure events or the inappropriate operating conditions.
