MARS 43330 Pressure Switch
The MARS 43330 Pressure Switch is a professional-grade high pressure cut-out designed for precise system protection in residential and commercial HVAC/R systems. Engineered as a fixed setting pressure control, this SPST high-pressure switch features an automatic reset (A/R) mechanism, opening the circuit on pressure rise at 400 PSI and closing it back at 280 PSI. This reliable electromechanical sensor is essential for preventing compressor damage due to excessive head pressure in R410A applications and legacy refrigerant setups. With a 1/4” female flare S.A.E. mounting including a built-in deflator, this compact pressure switch allows for direct-to-tubing installation, saving critical time on the job site. The hermetically sealed sensor and tamper-proof construction ensure consistent performance within a 24V to 240V range, rated for 6 amps at full load. This HVAC pressure switch replacement provides the heavy-duty durability required by veteran contractors for maintenance and emergency service calls.
Key Benefits- Automatic Reset Logic: Safely cuts out at 400 PSI and restores the circuit at 280 PSI without manual intervention.
- Universal Voltage Compatibility: Rated for use across 24V, 120V, and 240V systems, accommodating diverse equipment profiles.
- Simplified Installation: Features 18” leads and a 1/4” female flare fitting for rapid integration into existing liquid or discharge lines.
- Corrosion Resistant: Built with a hermetically sealed sensor to withstand harsh ambient and fluid temperatures.
What is the reset type for the MARS 43330?
This model is an auto-reset switch, meaning it will automatically close the circuit once the pressure drops back down to the 280 PSI set point.
Is this switch compatible with R410A systems?
Yes, the 400 PSI open / 280 PSI close specifications are frequently utilized as a safety cut-out in higher-pressure R410A air conditioning and refrigeration units.
How do I mount the MARS 43330?
The unit is designed for direct mounting via its 1/4" female flare S.A.E. connection, typically installed directly onto the service port or tubing.
