APPLETON Mercmaster™ III 400 Luminaires (for CSA Only)

Mercmaster™ III 400 Luminaires are ideal for use where energy efficient, high lumen out put is required in applications involving medium and high mounting heights. These enclosed and gasketed fixtures are suitable for CEC hazardous and adverse locations where flammable gases and vapors, combustible dusts, severe weather conditions or excessive moisture or dirt are present

Features

Typical applications include pulp and paper mills, processing plants, chemical plants, oil refineries, foundries, manufacturing plants, storage areas, waste and sewage treatment facilities and other areas where dust, water, dirt and rough usage are a problem
These medium base lamps accommodate 35 to 150 Watt high pressure sodium or metal halide (MH) lamps. There is a wide range of voltages and ballast types available
A choice of heat-resistant prismatic glass refractors (NEMA II or V) or heat-resistant globes are available. They thread directly into the ballast housing and seal against a high-temperature silicone rubber gasket
Modular design allows scores of fixture component combinations to meet installation and lighting needs. Mounting hoods include cone-shaped pendant, standard pendant, flexible pendant, ceiling and wall (tapped for 3/4″ or 1″ NPT), 25° angle stanchion
Reflector choice includes standard dome and 30° angle types, both made of fiberglass reinforced white polyester; highly resistant to unusually corrosive applications. Reflectors are vented for cooler, dirt-free operation and maintained lumen output.
Hinge has high lip for added safety during installation and servicing. Hinge and bolt construction assures 360° compression at all points on ballast housing gasket for positive sealing. Swing-away design of captive bolt and nut simplifies servicing
Body gaskets and globe gaskets are high-temperature silicone rubber
All Mercmaster III mounting hoods have provision for easy field installation of fuses in fixtures (see fuse kit listings on catalog pages)
