scope:

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time allor- nothing relays) for incorporation into low voltage equipment (circuits up to 1 000 V alternate current or 1 500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics, such as:

• general industrial equipment,

• electrical facilities,

• electrical machines,

• electrical appliances for household and similar use,

• information technology and business equipment,

• building automation equipment,

• automation equipment,

• electrical installation equipment,

• medical equipment,

• control equipment,

• telecommunications,

• vehicles,

• transportation (e.g. railways).

Compliance with the requirements of this standard is verified by the type tests indicated.

In case the application of a relay determines additional requirements exceeding those specified in this standard, the relay should be assessed in line with this application in accordance with the relevant IEC standard(s) (e.g. IEC 60730-1, IEC 60335-1, IEC 60950-1).
