P100AP-4C Johnson Controls Pressure Control

Overview

The Johnson Controls P100AP-4C is a compact, encapsulated, direct-mount single pressure control switch designed primarily for fan cycling and refrigeration applications. It features an automatic reset mechanism that activates when the system pressure fluctuates, specifically operating with a factory-calibrated setting where the switch opens on a pressure drop at 170 PSIG and closes at 250 PSIG. Its lightweight, non-adjustable design allows for cost-saving direct installation without the need for additional mounting brackets, providing a robust solution for demanding commercial environmental control systems.
