All-or-nothing electrical relays - Tests and Measurements - Part 7-18: Thermal resistance of the coil (IEC 94/738/CD:2022); Text in German and English
Abstract
This part of IEC 61810, 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.
