Description
The Johnson Controls P100DA-1C Pressure Control Switch is a compact electromechanical component used for high-pressure cut-out applications in refrigeration and air systems. It operates as a snap-action control that opens the circuit when system pressure reaches 410 PSI, helping protect compressors and related equipment from overload conditions. Designed with a manual reset mode, it requires user intervention to restore operation after a trip event. It features a fixed setpoint, diaphragm sensing element, and direct-mount configuration for quick installation on pressure lines. In HVAC systems, it supports system protection, load control, and safe operating limits during normal and fault conditions.
