It operates on systems up to 600 VAC and uses replaceable heater elements to provide inverse time overload protection that allows normal motor starting currents while safeguarding against prolonged overloads. Commonly installed in NEMA motor starters, motor control centers (MCCs), pumps, conveyors, compressors, fans, and industrial machinery. Maintenance teams and \u003ca href=\"https:\/\/plgautomation.com\/collections\/hmi-operator-interfaces\"\u003esystem integrators\u003c\/a\u003e use this relay for OEM replacement, motor starter repair, retrofit projects, and preventive maintenance of industrial motor control systems. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"797\" data-end=\"814\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"816\" data-end=\"1524\"\u003eThe Allen-Bradley 815-D0V4 is used in industrial motor control circuits requiring dependable thermal overload protection. It is compatible with Bulletin 815 motor starters and utilizes interchangeable heater elements selected according to the motor full-load current and application requirements. Typical applications include manufacturing equipment, HVAC systems, pumping stations, material handling equipment, compressors, and other industrial installations where reliable motor protection is essential. Allen-Bradley Bulletin 815 overload relays are designed to provide Class 20 protection with appropriate heater elements for most general-purpose motor applications. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1526\" data-end=\"1555\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1557\" data-end=\"2392\"\u003e• Manufacturer: Allen-Bradley (Rockwell Automation)\u003cbr data-start=\"1608\" data-end=\"1611\"\u003e• Part Number: 815-D0V4\u003cbr data-start=\"1634\" data-end=\"1637\"\u003e• Product Type: Thermal Overload Relay\u003cbr data-start=\"1675\" data-end=\"1678\"\u003e• Bulletin: 815\u003cbr data-start=\"1693\" data-end=\"1696\"\u003e• Relay Type: Eutectic Alloy Thermal Overload Relay\u003cbr data-start=\"1747\" data-end=\"1750\"\u003e• Maximum Operating Voltage: 600 VAC\u003cbr data-start=\"1786\" data-end=\"1789\"\u003e• Frequency: 50\/60 Hz\u003cbr data-start=\"1810\" data-end=\"1813\"\u003e• Protection Class: Class 20 (with standard heater elements)\u003cbr data-start=\"1873\" data-end=\"1876\"\u003e• Heater Elements: Replaceable Type N or Type W (application dependent)\u003cbr data-start=\"1947\" data-end=\"1950\"\u003e• Reset Type: Manual or Automatic (configuration dependent)\u003cbr data-start=\"2009\" data-end=\"2012\"\u003e• Mounting Style: NEMA Starter Mounting\u003cbr data-start=\"2051\" data-end=\"2054\"\u003e• Application: AC Motor Overload Protection\u003cbr data-start=\"2097\" data-end=\"2100\"\u003e• Construction: Open-Type Industrial Overload Relay\u003cbr data-start=\"2151\" data-end=\"2154\"\u003e• Features: Inverse time trip characteristics, replaceable heater elements, thermal overload protection, industrial-duty construction, and compatibility with Allen-Bradley Bulletin 815 motor starters. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2394\" data-end=\"2418\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2420\" data-end=\"2556\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Allen-Bradley 815-B0V4\u003cbr data-start=\"2444\" data-end=\"2447\"\u003e• Allen-Bradley 816-D0V4\u003cbr data-start=\"2471\" data-end=\"2474\"\u003e• Allen-Bradley 592-D0V4\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51727379366190,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e8958f34-6405-434b-be19-d6ec06e007c4.jpg?v=1770582652","url":"https:\/\/plgautomation.com\/products\/allen-bradley-815-d0v4-thermal-overload-relay-ac","provider":"PLG Automation ","version":"1.0","type":"link"}
