Overview
EN IEC 60519-4:2022/prA1:2025 is an amendment (Amendment 1, Committee Draft for Vote) to Part 4 of the IEC/EN 60519 series: Safety in installations for electroheating and electromagnetic processing - Particular requirements for arc furnace installations. Published for CENELEC/IEC parallel voting in 2025, this amendment updates safety and electrical-design requirements specifically for arc furnace installations in industrial electroheating applications. It is of particular interest to manufacturers, specifiers and safety engineers working with electric arc furnaces and associated high-voltage equipment.
Key topics and technical requirements
- High-voltage primary-side design and enclosure
All high-voltage equipment on the arc-furnace transformer primary side must be designed, constructed and enclosed in accordance with IEC 61936-1:2021 or IEC 62271. The chosen standard must be identified on the rating plate. - Insulation coordination and clearances (voltage thresholds)
- Arc furnaces with secondary voltages up to 1 000 V AC or up to 1 500 V DC: apply IEC 60664-1:2020.
- Arc furnaces with secondary voltages between 1 000 V AC and 3 600 V AC or 1 500 V DC and 5 000 V DC: IEC 60664-1:2020 may be applied exceptionally, but only with manufacturer-specified special requirements.
- Operational information and indicators
Control rooms must display visible status information for high-voltage switchgear and, where applicable, AC/DC disconnectors to support safe operation and maintenance. - Scope of electrical hazards
The amendment clarifies that electrical hazards considered are associated with currents/charges between 0 Hz and up to 100 Hz.
Applications and users
This amendment is directly applicable to:
- Manufacturers of arc furnaces and furnace transformers
- Plant electrical engineers and OEMs designing electroheating installations
- Safety and compliance officers preparing documentation for CE/CENELEC conformance
- Integrators specifying insulation coordination and switchgear for steelmaking, foundries and metallurgical plants
Practical uses include design verification, specifying switchgear/enclosures, rating-plate information, and control-room indicator requirements to improve operator safety and compliance.
