Overview
EN 60947-5-1:2017 (identical to EN 60947-5-1:2017 / IEC 60947-5-1:2016) is the international standard for electromechanical control circuit devices used in low‑voltage switchgear and controlgear. It applies to control circuit devices and switching elements intended for controlling, signalling and interlocking with rated voltages up to 1 000 V a.c. (≤1 000 Hz) or 600 V d.c. This fourth edition is a technical revision that replaces earlier editions and is published as the RLV version by IEC.

- Design and material requirements: New material tests and requirements to ensure durability and safety.
- EMC requirements: Revised conducted and radiated immunity and emission requirements to comply with modern electromagnetic compatibility expectations.
- Mechanical and electrical tests: Clarified test procedures and restructured subclauses (notably 7.1 and 8.2).
- Terminal and connection rules: New requirements for screwless‑type clamping units and updated tables for conductor/clamping data (updated Tables 4–5 and new Tables 6–9).
- Documentation and figures: Additions such as a new Figure 10 and new Annex N for supplementary guidance.
- Conformity with EU directives: Informative Annexes ZZA and ZZB map the standard to Directive 2014/30/EU (EMC) and Directive 2014/35/EU (Low Voltage Directive), supporting presumption of conformity where applicable.
Practical applications
- Design and type‑testing of pilot switches, push‑buttons, rotary switches, contactor relays and other electromechanical control devices.
