The ATEX certified control stations provide safe circuit control and/or selection in potentially explosive atmospheres. Pilot lights are available to provide visual assurance that an electrical function is being performed at a remote or local location. These polyester control stations are ideal for the control of equipment at power, chemical and petrochemical plants, petroleum refineries, re-verse osmosis plants, pulp and paper processing plants and various other industrial applications.

Appleton Unicode 2 Series uses the Ex de method of protection which eliminates the need for external seals. Unicode 2 Series features a choice of DIN rail mounted high performance contact block suitable for low intensity (less than 5 mA). TS35 rail mounted components are held securely in place during operation and easily removed for service.

Contact block technical data: IEC rated operating voltage (Ue): 500 Vac – 110 Vdc. IEC switching capacity: AC12: 16 Amp/400 Vac, AC14: 10 Amp/400 Vac, AC15: 6 Amp/500 Vac, DC13: 2 Amp/24 Vdc and 1 Amp/110 Vdc. NEMA switching capacity: A600: 10 Amp/600 Va.

Selector switch technical data: IEC rated operating voltage: 690 Vac. IEC rated operating current: maximum 16 Amp. IEC switching capacity: AC1: 16 Amp/690 Vac, AC15: 16 Amp/415 Vac, AC3: 8 Amp/500 Vac, AC3: 4 Amp/690 Vac, AC3: 16 Amp/690 Vac, DC1: 10 Amp.
