Johnson Controllers Temperature Controller A19AUC-2C Fixed Differential For Hazardous Locations

Johnson Controllers Mechanical Temperature Controller A19AUC-2C Fixed Differential For Hazardous LocationsThe A19AUC and A19BUC Mechanical Temperature Controllers are designed for use in locations where flammable and explosive mixtures of vapors and gases with air or combustible dust in air are present. Listed at UL for Hazardous Locations, Class I, Group D (NEMA 7) and Class II, Groups E, F and G (NEMA 9) as defined in the National Electrical Code. The SPDT contact unit provides open high or close high action for either heating or cooling applications. The Temperature Controllers are available to cover sensed temperatures from -30 to 475°F (-34 to 246°C). Closed tank fittings and bulb wells are available for immersion applications. All Series A19 Temperature Controllers are designed for use only as operating controls. Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of the installer to add devices (safety, limit controls) or systems (alarm, supervisory systems) that protect against, or warn of, control failure.Features: Dependable and precise snap-acting contacts enclosed in a dust protected case and the liquid filled sensing element are field proven.Unaffected by barometric pressure and cross ambient temperature problems for repeat accuracy.SPDT contacts for use on either heating or cooling applications.UL Listed, CSA Certified for ¿Hazardous Locations.¿ Product Specifications BRANDJohnson Controls CAPILLARY LENGTH FEET6 BULB SIZE INCHES3/8 x 5 MAXIMUM BULB TEMPERATURE °F (°C)140 (60) DIFFERENTIAL TEMPERATURE °F3.5 TEMPERATURE CONTROL RANGE °F20 to 80 VOLTAGE240 / 120 NEMA RATINGHazardous Location STAGESSingle SWITCH ACTIONSPDT TYPEHeat & Cool LISTING, RATING, CERTIFICATIONUL Listed LIMITED WARRANTY YEARS1 MANUFACTURER'S PART NUMBERA19AUC-2C
