Low Pressure Control Switch R22 : AFTC-PS-001
This image marks a shift from refrigerant service valves to a critical safety component: a Fixed Capsule Low Pressure Cut-Out Switch used to protect HVAC compressors from running without refrigerant or freezing up.
📋 Technical Specifications
- Model Number:
AFTC-PS-001 - Component Type: Low Pressure Control Switch
- System Design Parameter: Low Pressure R22 (Pre-calibrated for standard classic HCFC R-22 system temperature-pressure curves).
- Reset Style: Automatic Reset (Automatically opens and closes the circuit based on pre-set mechanical pressure thresholds).
⚙️ Factory Pressure Setpoints
The switch body features exact stamped calibration limits (measured in PSI):
- OPEN: 25 +/- 5 PSI → The internal switch contacts will trip open to immediately shut off the compressor if the suction line pressure drops down to 25 PSI (protecting against a total loss of charge or a frozen coil).
- CLOSE: 50 +/- 5 PSI → The switch contacts will close (re-engage) to allow the compressor to restart once pressure safely recovers back up to 50 PSI.
🔧 Structural Design & Wiring
- Brass Connection Fitting: The bottom hex nut contains a standard internal female thread designed to screw directly onto a 1/4″ flare service port or access fitting on the suction line.
- Electrical Control Leads: Features a pair of insulated blue lead wires designed to splice directly into the 24V or 220V safety control loop of your contactor coil or control board.
