Low Pressure Safety Control Switch R410 : AFTC-PS-003
This component is a Fixed Capsule Low Pressure Cut-Out Switch specifically calibrated to match the higher operational pressure curves of modern refrigerants.
📋 Technical Specifications
- Model Number:
AFTC-PS-003 - Component Type: Low Pressure Safety Control Switch
- System Design Parameter: Low Pressure R410 (Pre-calibrated for modern, eco-friendly R-410A refrigerant systems)
- Reset Style: Automatic Reset (The switch closes the circuit again on its own once pressure returns to a safe level)
⚙️ Factory Pressure Setpoints
The silver label wrapped around the capsule lists the precise mechanical trip points (measured in PSI):
- OPEN: 40 +/- 5 PSI → The internal electrical contacts will trip open to immediately shut off the compressor if the suction line pressure drops down to 40 PSI. This protects the compressor from running under a vacuum, freezing the evaporator coil, or operating with a major refrigerant leak.
- CLOSE: 70 +/- 7 PSI → The switch contacts will close (re-engage), allowing the system to safely restart once the low-side suction pressure recovers back up to 70 PSI.
🔧 Structural Design & Wiring
- Brass Mechanical Connection: The bottom brass hex nut contains internal female threads designed to thread straight onto a standard 1/4″ flare access valve on the low-pressure suction line.
- Electrical Control Leads: Features a pair of long, insulated blue lead wires designed to wire directly into the series safety loop of your HVAC control board or 24V/220V magnetic contactor coil.
