Product Details
Series 302 heat detectors are designed for use in normal environments as well as environments where the detectors are subject to weather, moisture (internal condensation), and explosive atmospheres. They are normally-open devices that close an electrical circuit upon activation. All models feature rate compensation, with the 302-ET-135 offering a 135°F (57.2°C) fixed temperature rating. This all-weather heat detector includes a plastic hexagonal grip bushing with 1/2" conduit threads for attachment to a threaded hub cover or any outlet box. For indoor or outdoor use when a watertight seal is needed, a weatherproof box is required and it operates with Stonco27 or equivalent. The detectors are self-restoring, hermetically sealed, shock and corrosion resistant, and tamperproof, ensuring reliability in various conditions.
