UL 61810-1

Standard for Electromechanical Elementary Relays - Part 1: General Requirements

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).
