82-14126 consists of a clear, tamperproof, super tough polycarbonate cover, housing for an instructional operation label, gasket, NEMA 4X conduit hub, fan, silicone laminate heater and four inch deep NEMA 3R backbox. The standard 82-14126 accommodates most manual pull stations and is marked with an "IN CASE OF FIRE" message, but can be custom labeled and used to protect many other devices.
The thermostatically controlled 240 VAC heater and continuous duty fan maintain a uniform temperature inside the enclosure when temperatures drop. Applications include, but are not limited to, refrigerators, freezers, meat packaging plants, arctic environments, ocean rigs, slaughter houses, etc. This enclosure is designed to protect UL Listed 38 and 2017 initiating devices at temperatures down to -70°F (-57°C).
