MARS 43341 N/O Low-Pressure Switch A/R 1/4" 20 PSI-CL, 5 PSI-OP

The MARS 43341 Normally Open Low-Pressure Switch serves as a dependable automatic reset equipment that protects HVAC systems, through proper pressure management. The switch operates effectively between 5 PSI open and 20 PSI close pressure points to monitor low-pressure situations in air conditioning and refrigeration systems. This Switch integrates easily into different HVAC system setups, because it uses 1/4" connections and works with 24-250V. The auxiliary contact operates in open mode by default to activate only when pressure reaches below the specified threshold and protects compressors while maintaining system performance. The automatic reset function enables the system to resume normal operation after pressure stabilizes and decreases operational interruptions.
