MARS 43343 Pressure Switch
The MARS 43343 Low Pressure Switch is a high-performance HVACR safety control designed for precise low-pressure cut-out in refrigeration and air conditioning systems. Engineered with a single-pole, single-throw (SPST) normally open configuration, this switch provides a reliable manual reset alternative or automatic safety shut-off. This unit features a factory-set 25 PSI cut-in and 10 PSI cut-out (25#CI / 10#CO), ensuring equipment protection against low-charge conditions or coil freeze-ups. The hermetically sealed sensor and tamper-proof construction make it a staple for technicians working with R410A refrigeration systems and traditional refrigerants. With a 1/4" SAE female flare mounting and 18-inch leads, it allows for direct, lightweight mounting on tubing, minimizing vibration stress. Rated for 6 amps at 24-240V, the MARS 43343 is a versatile OEM replacement pressure switch that meets UL and CSA standards for commercial and residential applications.
Key Benefits- Fixed Pressure Settings: Precise 10 PSI cut-out and 25 PSI cut-in prevent compressor damage during low-pressure events.
- Durable Construction: Features a hermetically sealed sensor and tamper-proof housing for long-term reliability in harsh environments.
- Universal Compatibility: Optimized for R410A applications and compatible with most non-corrosive refrigerants.
- Easy Installation: The 1/4 inch female flare S.A.E. mounting enables direct connection to the system without additional brackets.
- Broad Voltage Range: Internal SPST contacts are rated for 24V to 240V, covering diverse electrical requirements.
What are the specific pressure settings for the MARS 43343?
This switch is factory-set to open the circuit (cut-out) when pressure drops to 10 PSI and close the circuit (cut-in) when pressure rises to 25 PSI.
Is the MARS 43343 an automatic or manual reset switch?
The MARS 43343 is an automatic reset pressure switch, meaning it will reset the circuit once system pressure reaches the 25 PSI cut-in threshold.
What size fitting does this low pressure switch use?
It utilizes a standard 1/4" SAE female flare connection with an internal deflator, designed for direct mounting on refrigeration service ports.
