This control operates on a sensing range of 35 to 45 degrees Fahrenheit with an 8-degree Fahrenheit differential, making it well suited for freeze protection applications in air handling units, cooling coils, and refrigeration equipment. The auto reset feature allows the switch to automatically restore normal operation once temperatures rise back above the setpoint, reducing the need for manual intervention and minimizing system downtime.\u003c\/p\u003e\u003cp\u003eThe A11B-1C accepts voltages from 120 to 240 volts AC, giving it broad compatibility across a wide range of commercial and light industrial HVAC control circuits. HVAC technicians and refrigeration service professionals rely on low temperature cutouts like this one to act as a safety device that opens a control circuit when coil or air temperatures drop below a safe threshold. This prevents compressor damage, coil freezing, and related equipment failures that can result from sustained low-temperature conditions.\u003c\/p\u003e\u003cp\u003eThe capillary bulb sensing element reads ambient or coil temperatures accurately, triggering the switch at a consistent setpoint. The 20-degree Fahrenheit capillary break-fall rating indicates the length and configuration of the sensing element, allowing it to cover a broad surface area for more reliable average temperature detection across a coil face or duct. This makes the A11B-1C a practical choice for commercial rooftop units, split systems, air handlers, and walk-in cooler controls where freeze stat protection is a code or manufacturer requirement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAuto reset operation restores circuit continuity automatically after temperature recovery\u003c\/li\u003e\n\u003cli\u003eSensing range of 35 to 45 degrees Fahrenheit with 8-degree Fahrenheit differential\u003c\/li\u003e\n\u003cli\u003eCompatible with 120 to 240 volt AC control circuits for broad system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Penn A11B-1C low temperature cutout thermostat provides reliable freeze protection for HVAC and refrigeration systems with auto reset functionality and wide voltage compatibility, making it a dependable safety control for commercial installations.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PENN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A11B-1C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 35 to 45 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifferential\u003c\/strong\u003e: 8 degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Auto Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 to 240V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapillary Rating\u003c\/strong\u003e: 20F Cap Brk Fall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78502808264\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENN","offers":[{"title":"Default Title","offer_id":51120976625970,"sku":"A11B-1C","price":596.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304882250.jpg?v=1777744827","url":"https:\/\/voomisupply.com\/products\/penn-a11b-1c-low-temperature-cutout-thermostat-35-45f-auto-reset","provider":"Voomi Supply","version":"1.0","type":"link"}
