The Johnson Controls A19BBC-2C is an electromechanical thermostat that provides line-voltage temperature control with a sensing coiled air bulb and SPDT contacts. It operates from -30 to 100 F with an adjustable differential of 3 to 12 F and convertible screw or knob adjustment. AC full-load ratings include 16 A at 120 V, 9.2 A at 208 V, and 8 A at 240 V; designed for use with copper conductors.
Operating range -30 to 100 F with adjustable differential 3 to 12 F and convertible screw or knob control.
SPDT (single-pole double-throw) switching with coiled air bulb sensing; rated AC full-load: 16 A @120 V, 9.2 A @208 V, 8 A @240 V.
Designed for line-voltage control of low-energy circuits and compatible with copper conductors; direct replacement for several White Rogers, Ranco, and Honeywell models.
