Q: What does the standard BS EN 61439 mean?

The standard DIN EN / IEC 61439 replaced the standard 60439 at the end of 2014. The standard describes the design and test specifications for low-voltage switchgear combinations. The standard defines the safety requirements for devices that are used to distribute electrical energy in industry, in private households and on construction sites. The standard guarantees a higher safety standard and is used, for example, for energy distributors, switchgear and distribution cabinets. More information

Q: What is the difference between AMELAN and Polycarbonate?

The housings and elements of many of our plugs and sockets are made of the thermoplastic AMAPLAST® (PC/PA), a robust engineering grade plastic which offers good electrical insulation as well as being very strong and resistant to heat, seawater, oil and petrol. The engineering grade thermoplastic PBT (formerly AMELAN), on the other hand, is a special plastic that we offer for the housings and elements of some plugs and sockets. This plastic provides protection against chemicals and other aggressive substances such as oils, fuels, greases and alkalis. Our products with this special plastic can be used, for example, in the food and chemical industries or in refineries.
