The Penn Controls P28AA-2 Oil Pressure Cutout Switch monitors oil pressure and triggers a circuit cutout at a 70 PSI threshold to protect lubrication systems and engine components. It operates on 120–240 V AC and supports 50/60 Hz input, enabling compatibility with standard electrical supplies. This model is intended for use in engines and oil‑lubricated machinery where automatic shutoff based on oil pressure helps prevent damage.
