U4 | Unicode™ Series 2-Polyamide Control Stations | ATEX, IECEx, UKEX | Zones 1 and 2 – 21 and 22 – Emergency Stop with Key-Reset Emergency Release (NO+NC)

Applications

• For use in IEC governed hazardous areas. Polyamide is not recognized for use in any NEC/CEC governed hazardous areas.
• Local control stations and motor control stations for use in hazardous areas covering the broadest possible range of

applications.

• Control of equipment at:

— Power plants

— Chemical and petrochemical plants
