IEC 61810-10:2019, with functional and safety aspects, applies to electromechanical elementary relays (non-specified time all-or-nothing relays) with high capability requirements like breaking or short circuit capabilities and similar for incorporation into low-voltage equipment. These relays may have a specific design to extinguish the electric arc between contacts (e.g. by magnetic blow-out), or use an insulation coordination not covered by IEC 61810-1 (e.g. by gas filled contact chambers), or require safety assessments not covered by IEC 61810-1 (e.g. for higher loads).
It defines additional requirements for high-capacity relays with generic performance intended for use in applications in smart grids, electric vehicles and other applications where, for example, battery charge/discharge switching is used, such as:
. electrical energy storage (EES) systems,
. solar photovoltaic energy systems,
. electric road vehicles (EV) and electric industrial trucks,
. power electronic systems and equipment,
. secondary cells and batteries,
. road vehicles.
Compliance with the requirements of this standard is verified by the type tests indicated.
