Additional functional aspects and safety requirements for high-capacity relays

Publication Date: 07 October 2019

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.
