It uses a liquid-filled sensing element that is environmentally friendly and maintains a constant differential throughout the entire operating range. Rated for 120 to 277 VAC, this control is built for reliability in demanding commercial and industrial environments. Its compact alloy steel enclosure keeps the unit protected while fitting into tight equipment spaces. HVAC technicians and controls specialists are the typical installers of this device.\u003c\/p\u003e\n\u003cp\u003eThe A19ABA-40C is suited for single-stage temperature control in commercial HVAC systems, refrigeration equipment, and industrial process applications requiring line voltage switching. Its wide temperature range capability and choice of sensing element styles make it adaptable to a variety of system configurations. The fixed or adjustable differential option gives technicians flexibility when setting up control sequences for unit coolers, condensing units, or air handling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-stage temperature control with liquid-filled sensing element\u003c\/li\u003e\n  \u003cli\u003eWide temperature ranges available to suit varied application requirements\u003c\/li\u003e\n  \u003cli\u003eConstant differential maintained throughout the entire operating range\u003c\/li\u003e\n  \u003cli\u003eFixed or adjustable differential options for flexible setpoint control\u003c\/li\u003e\n  \u003cli\u003eCompact alloy steel enclosure for durable, space-efficient installation\u003c\/li\u003e\n  \u003cli\u003eVariety of sensing element styles available for different mounting configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install line voltage mechanical thermostat for single-stage temperature control applications operating on 120 to 277 VAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or controls specialist familiar with line voltage wiring practices and applicable NEC requirements. Disconnect and lock out all power to the circuit before removing the existing control or making any wiring connections. Verify the supply voltage matches the rated 120 to 277 VAC range before energizing. Mount the sensing element according to the manufacturer's guidelines for the specific sensing style used to ensure accurate temperature response.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 to 277 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Single-stage mechanical thermostat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensing Element\u003c\/strong\u003e: Liquid-filled, environmentally friendly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 3.19 inches x 2.60 inches x 10.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.00 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PENN CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A19ABA-40C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENN CONTROLS","offers":[{"title":"Default Title","offer_id":52030503092530,"sku":"A19ABA-40C","price":149.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/226998903.png?v=1790019431","url":"https:\/\/voomisupply.com\/products\/penn-controls-a19aba-40c-line-voltage-mechanical-thermostat","provider":"Voomi Supply","version":"1.0","type":"link"}
