- Electrical equipment manufacturers
- Test houses
- Stockists
- Electrical design engineers
Why should you use BS EN 60947-3:2020?
This European standard is the definitive international code for switches, disconnectors, switch-disconnectors and fuse-combination units. It specifies general rules and common safety requirements and provides essential constructional, performance and test requirements to enable the design, evaluation and safe operation of switches, disconnectors, switch-disconnectors and fuse-combination units.
The standard is designed to be used with the BS EN 60947 series and so is compatible with a large range of coordinating components. It has been fully revised to reflect advances in digital interfaces and equipment.
BS EN 60947-3:2020 covers:
- Definitions
