IEC 60947-4 is a part of the IEC 60947 series that specifically covers contactors and motor starters. The standard provides detailed requirements for the design, testing, and performance of contactors and motor starters used in low-voltage applications. The standard aims to ensure that these devices operate safely and reliably, and are compatible with other equipment in the electrical system.
The IEC 60947-4 PDF can be obtained from the International Electrotechnical Commission (IEC) website or from authorized distributors. The standard is available in both English and French languages.
Almost, but not exactly. EN 60947-4 is the European harmonized version, which includes specific deviations for the EU Low Voltage Directive (LVD). If selling in Europe, you need the EN version, which references the IEC text but adds national differences.
This article provides a deep dive into IEC 60947-4, its structure, its technical requirements, and—most importantly—how to handle the for legitimate use.
