Control Enclosures for Hostile Environments
Standard control models ELS, LCS/LHS, LC, RSA, DLC, and PCT are open-style. Models with contactors are attached to a 6-7/8" x 8-3/4" panel. Use NEMA 3 and NEMA 4-JIC enclosures for these models with or without contactor mounting panels. Alarm and indicator lamp options are also available. Contact Curtis Industries or your local representative for more information.
NEMA 3 Enclosures - Weather-Resistant for Outdoor Applications
Neither rain, nor snow, nor sleet can penetrate these durable enclosures. Use them outdoors or in, wherever dripping water presents a problem. Made of heavy-gauge steel finished in satin gray enamel. N3 is for standard control models, while those accepting the larger contactor mounting panels are designated N3C. All enclosures meet NEMA specifications for general purpose dust resistance.
NEMA 4-JIC Enclosures – Water Tight and Oil Tight
Use in areas that are regularly hosed down. They are suitable for the worst weather, on board ship, car wash, dairy, or brewery applications. Made of extra-heavy 14-gauge steel with welded seams, external mounting feet, and solid neoprene cover gasket. These grey hammer tone enamel-finished units accept standard and contactor mounting panel controls. Enclosures also meet NEMA 12 specifications for dust, dirt and oil protection.
Auxiliary Contactors – For Loads Exceeding Those of Standard Relays
When loads exceed the 10 amp/ 120VAC rating of our standard relays, a contactor is necessary. These small, ruggedly built units are available in 24, 120 and 240VAC coil voltages to match the control input supply voltage. Made with heavy-duty DPST-NO-DB contacts rated 1 HP/120VAC or 2 HP/240VAC. Terminals are No. 10 pressure screws with .250" double quick-connect tabs. Contactor/control assemblies are pre-wired for convenience. Also, order any standoff or flange-mounted control with the auxiliary contactor. Track-mounted controls are available with auxiliary contactors on special order only. Contact Curtis Industries or your local representative for more information.
