Mercmaster III HID 50-250 Watt Luminaires 

• Enclosed and gasketed fixtures suitable for use in:
• Marine and wet locations
• Areas where flammable gases and vapors or combustible dusts are present under conditions defined by the National Electrical Code as Class I, Division 2; Class II, Division 1 and 2; and Class III
• For Zone 2, the method of protection is AEx nA nR – Restricted Breathing/Nonsparking or AEx nR – Restricted Breathing
• Non-hazardous locations where severe weather conditions, excessive moisture, dirt, dust or corrosive atmospheres are encountered
• 18% cooler operation allows use in ambient temperatures up to 149°F/65°C depending on fixture component combinations
• Typical applications include:
• Pulp and paper mills
• Processing plants
• Chemical plants
• Oil refineries
• Foundries
• Manufacturing plants
• Storage areas
• Marine applications
• Fixtures have NEMA 4X listing
• Suitability includes listing for use where there may be simultaneous exposure to combustible dusts and flammable gases and vapors (see catalog for specific compliance data)

• Cast copperfree aluminum mounting hoods, bodies and guard; stainless steel hardware; fiberglass reinforced white polyester reflectors
• A choice of heat-resistant prismatic glass refractors (NEMA I, III or V) or heat-resistant globes which thread directly into ballast housing (Photometrics available upon request)
• Modular design allows scores of fixture component combinations to meet installation and lighting needs
• Many most used combinations are offered prewired and assembled, complete with lamp, packaged in a single carton and ready to install
• Mogul lamp types and wattages:
• HPS 50 W-150 W
• PSMH 70 W-250 W
• Mounting hoods include cone shaped pendant hood, standard pendant, flexible pendant, ceiling and wall pendants (tapped for 3/4” or 1” NPT), 25° angle stanchion, and 90° (straight) stanchion (both tapped for 1-1/4” or 1-1/2” NPT)
• Cone hood fixtures for pendant mounting shed dust, dirt and combustible fibers, and provide increased surface area to ensure effective heat dissipation
• Standard dome or 30° angle reflectors made of fiberglass reinforced white polyester, highly resistant to corrosive atmospheres and vented for cooler operation and maintained lumen output
• Hinge has high lip for added safety during installation and servicing
• Hinge and bolt construction ensures 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
• Capacitors are non-PCB type, thermally isolated from ballast
• Mogul base porcelain socket with nickel-plated contacts has 200°C/392°F welded leads, prewired to the ballast to ensure trouble free operation in high ambient temperatures
• HPS ballasts are High Power Factor (min. P.F. 90%)
• A wide range of voltages available (120 to 600 Volt) and ballast types (Reactor, CWA, CWI and Super CWA)
• All Mercmaster III mounting hoods have provision for easy field installation of fuses in fixtures
• Ground wire provided to bond hood and ballast housing for electrical protection
• The AEx nA nR / Ex nR (CSA*)  factory sealed Mercmaster III prevents vapors and gases from entering the globe chamber – no seals or putty required
• The AEx nR Mercmaster III fixture requires all wiring entries to be sealed
