Full title and description

Electromechanical elementary relays - Part 10: Additional functional aspects and safety requirements for high-capacity relays. This international standard specifies additional functional and safety requirements and type-test verification for electromechanical elementary relays designed for high breaking, short‑circuit or similar heavy-duty capabilities (for example relays with arc‑extinguishing designs or gas‑filled contact chambers) intended for incorporation into low‑voltage equipment and applications such as electrical energy storage, photovoltaic systems, electric vehicles and other power‑electronics environments.

Abstract

IEC 61810-10:2019 supplements the general requirements of the IEC 61810 series by addressing relays with high capacity requirements that require special functional and safety considerations beyond IEC 61810-1. It defines additional design, insulation coordination and safety assessment requirements and specifies the type tests used to verify compliance for use in demanding applications including battery charge/discharge switching and power‑electronic systems.

General information

• Status: International standard (published / active).
• Publication date: 11 July 2019.
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 29.120.70 (Relays).
• Edition / version: Edition 1.0 (2019).
• Number of pages: 128 (IEC published base document).

Scope

The standard applies to electromechanical elementary relays (non‑specified time, all‑or‑nothing relays) with high capability requirements such as high breaking capacity or short‑circuit withstand and to designs that use special arc‑extinguishing methods or insulation coordination not covered by IEC 61810‑1. It provides additional requirements and test procedures for high‑capacity relays intended for incorporation into low‑voltage equipment and for use in applications including electrical energy storage (EES), solar photovoltaic systems, electric road vehicles and industrial trucks, power electronic equipment, secondary cells and batteries. Compliance is verified by the type tests indicated in the document.

Key topics and requirements

• Additional functional aspects for high‑capacity electromechanical relays (beyond general relay requirements).
• Safety requirements and assessments for high breaking and short‑circuit capacities.
• Design considerations for arc extinguishing (e.g., magnetic blow‑out) and special insulation coordination (e.g., gas‑filled contact chambers).
• Specified type tests and verification methods to demonstrate compliance for heavy‑duty applications.
• Application guidance for use in smart grids, EES, PV systems, EVs and power‑electronic environments.

These topics and test foci are intended to ensure reliable operation and personnel/equipment safety where relays switch high currents, voltages or battery systems.

Typical use and users

Primary users include relay and contact manufacturer design and compliance teams, product safety and test laboratories, certification bodies, OEMs of power‑electronic and battery systems, EV and energy‑storage system designers, and standards engineers responsible for component selection and system safety. The standard is used to define design targets, test protocols and acceptance criteria for relays used in high‑capacity switching applications.

Related standards

IEC 61810-10 is part of the IEC 61810 series and is intended to be used in conjunction with IEC 61810‑1 (Electromechanical elementary relays – Part 1: General and safety requirements). National and regional adoptions exist (for example EN/UNE/BS adoptions of EN IEC 61810‑10:2019). Related product and equipment standards for low‑voltage switching and safety (for example various IEC/EN series on switchgear and protective devices) are commonly referenced in system‑level compliance and design work.
