The current rating of the contactor depends on utilization category. Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces; AC-2 - Starting of slip-ring motors: starting, switching-off; AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up ...
The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. IEC 60027 Letter symbols to be used in electrical technology; IEC 60028 International standard of resistance for copper

Schematic representation of measurement categories. Measurement category is a method of classification by the International Electrotechnical Commission (IEC) [1] of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial).
IEC Standards that are not jointly developed with ISO have numbers in the range 60000–79999 and their titles take a form such as IEC 60417: Graphical symbols for use on equipment. Following the Dresden Agreement with CENELEC the numbers of older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027 ...
An electrical code is a term for a set of regulations for the design and installation of electrical wiring in a building. The intention of such regulations is to provide standards to ensure electrical wiring systems are safe for people and property, protecting them from electrical shock and fire hazards.
The Remote Terminal Unit monitors data points and generates events when it determines that the data should be reported (for example, when it changes value). These events are each placed in one of three buffers, associated with "Classes" 1, 2 and 3. In addition to these, Class 0 is defined as the "static" or current status of the monitored data.
