The Johnson Controls P100CC-9 is a rugged, encapsulated pressure control engineered for reliable high-side or low-side refrigerant circuit protection in commercial HVAC and refrigeration systems. Its direct-mount design simplifies installation by attaching directly to the system without additional tubing, while the included conduit clamp provides secure wiring management right out of the box.
How It Works
This SPST (Single-Pole, Single-Throw) control is configured to open on a pressure rise, cutting power to the circuit when system pressure exceeds the factory-set trip point. Once pressure drops back to the close set point, the automatic reset function restores normal operation without requiring manual intervention — minimizing downtime and service calls.
