1 Scope

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1000 V alternate current or 1500 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:

1. • general industrial equipment,

2. • electrical facilities,

3. • electrical machines,

4. • electrical appliances for household and similar use,

5. • information technology and business equipment,

6. • building automation equipment,

7. • automation equipment,

8. • electrical installation equipment,

9. • medical equipment,

10. • control equipment,

11. • telecommunications,

12. • vehicles,

13. • 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).
