P100AP-3C Johnson Controls Pressure Control

Overview

The Johnson Controls P100AP-3C is a compact, economical, encapsulated pressure switch designed for direct-mount, snap-action, on/off pressure control. Part of the P100 Series, this standard-duty device features a non-adjustable, factory-calibrated setpoint built primarily for low-pressure cut-out or condenser fan cycling applications in refrigeration and air conditioning systems. It is engineered to provide precise and repeatable pressure control across a wide range of ambient conditions.

Features

• Compact size and lightweight construction allow for direct installation onto refrigeration piping without additional mounting brackets.
• Tamper-proof, factory-calibrated pressure setpoint ensures long-term operational accuracy.
• Dust-tight, encapsulated switch enclosure providing reliable performance.
• Single-Pole, Single-Throw (SPST) open-low switch action.
• Automatic reset function that triggers when the pressure rises to the close setpoint.
