A19ABA-40CQ Johnson Controls Temperature Control

Overview

The Johnson Controls A19ABA-40CQ is a single-stage mechanical remote bulb temperature control designed for reliable regulation in heating, ventilating, and refrigeration applications. It features an environmentally friendly, liquid-filled sensing element and capillary to provide stable temperature control that is unaffected by cross-ambient conditions. Housed in a compact NEMA 1 enclosure, this controller uses a single-pole single-throw (SPST) switch configuration designed to open on low temperature.
