Description
The MARS 43331 High-Pressure Switch operates as an SPST automatic reset switch that protects HVAC systems through high-pressure level monitoring and control functions. The equipment opens itself at 400 PSI but closes at 300 PSI to stop system overpressure which safeguards vital system components. This Switch operates between 24-250V and works with different air conditioning and refrigeration units such as residential HVAC systems. The system efficiency improves while equipment longevity extends and compressor failure risk decreases because of its ability to prevent pressure buildup. The part provides durable operation in harsh conditions which makes it an indispensable safety element for HVAC system reliability.
