FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

The EN IEC 61095:2025 standard provides comprehensive guidelines for electromechanical contactors intended for household and similar applications. This latest edition, which supersedes the 2009 version, encompasses significant technical advancements, ensuring that the standard remains relevant amidst the evolving electrical landscape. The scope of this standard is notably robust, covering air break contactors with specific ratings-specifically, those not exceeding 440 V AC and operational currents of 63 A for AC-7a, alongside more defined categories for AC-7b, AC-7c, and AC-7d. This specificity is instrumental for manufacturers and users alike, ensuring that electromechanical contactors are correctly utilized within their operational limits. One of the standout strengths of EN IEC 61095:2025 is its incorporation of updated requirements that reflect the latest technological trends, such as screwless terminals and the increasingly popular LED lamps. The creation of a dedicated contactor category-AC-7d-along with tailored tests for the switching of LED technologies illustrates the standard's adaptability to market developments, ensuring compatibility and safety in domestic settings. Additionally, the standard also addresses modern advancements in technology with the inclusion of requirements for contactors featuring electronically controlled electromagnets. This forward-thinking approach allows the standard to encompass newer technologies that have been in the market for some time but have lacked explicit guidelines. Furthermore, the incorporation of EMC tests and considerations for embedded software in contactors showcases a proactive stance toward addressing contemporary challenges in electronic control and software design. Overall, EN IEC 61095:2025 illustrates a comprehensive understanding of the current and future needs in electromechanical contactor applications for households, making it an essential reference for compliance and best practices in design and usage.
Die EN IEC 61095:2025 ist eine umfassende Norm, die sich mit elektromechanischen Kontaktoren für Haushalts- und ähnliche Zwecke beschäftigt. Der Anwendungsbereich dieser Norm ist klar definiert: Sie bezieht sich auf Luftunterbrechungskontaktoren, die für Schaltungen mit einer Nennspannung von bis zu 440 V AC und einer Nennbetriebsstromstärke von maximal 63 A (Nutzungsart AC-7a) sowie 32 A für die Nutzungsarten AC-7b, AC-7c und AC-7d vorgesehen sind. Darüber hinaus umfasst die Norm Anforderungen an den Nennkurzschlussstrom, der nicht mehr als 6 kA betragen darf. Eine der Stärken der EN IEC 61095:2025 ist die technische Überarbeitung im Vergleich zur vorherigen Edition von 2009.
