P170EA-14C Johnson Controls Pressure Control

Overview

The Johnson Controls P170EA-14C is a MICRO-SET low pressure control switch designed primarily for commercial refrigeration and air conditioning systems. This single pressure control features an adjustable single-pole double-throw (SPDT) switch mechanism actuated by a pressure bellows, providing automatic reset capability for reliable operating control based on system pressure changes.

Features

• Sight-Set Calibrated Pressure Adjustment: Features a visible scale that allows for clear setpoint adjustment without requiring the removal of the NEMA 1 enclosure cover.
• MICRO-SET Differential Option: Provides precise, adjustable differential adjustment to protect critical low pressure applications.
• Heavy-Duty Steel Enclosure: Housed in an all-steel case and cover built to offer long-lasting, rugged protection for internal components.
• SPDT Contact Configuration: Incorporates an SPDT switch action allowing for simultaneous control of the primary compressor load and optional auxiliary devices like alarms.
