Interesting Fact and Applications

Control Relay for Ex Applications

Fast and flexible: Relays from WAGO are suitable for use in Zone 2 explosive atmospheres and thus cover a wide range of applications.

Hazardous Areas

Hazardous areas arise in various applications including the chemical industry, during the production of crude oil or natural gas and in the food industry. These are divided into Zones 0, 1 and 2 according to the frequency and duration of occurrence of potentially explosive atmospheres. WAGO relays are suitable for use in Zone 2 explosive atmospheres. For devices that may be used in hazardous areas, labeling is mandatory.
