Electromechanical Elementary Relays – Part 1: General and Safety Requirements
UL 61810-1
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:

• 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).
