Low-voltage switchgear and controlgear. Switches, disconnectors, switch-disconnectors and fuse-combination units
Also Known As:
What is BS EN 60947-3:2020 about?
This is Part 3 in a multi-part series of European standards on low-voltage switchgear and controlgear. BS EN 60947-3:2020 sets out the requirements that apply to switches, disconnectors, switch-disconnectors and fuse-combination units.
Who is BS EN 60947-3:2020 for?
- 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
- Characteristics
- Information supplied with the equipment
- Normal service, mounting and transport conditions, decommissioning and dismantling
- Constructional and performance requirements
- Verification of characteristics and performance
- Energy efficiency aspects
- Environmental aspects
What’s new about BS EN 60947-3:2020?
- New critical load current tests for DC switches
- New categories for high-efficiency motors switching
- New Annex E for connection to aluminium conductors
- New Annex F for power losses measurement
