A blue plug, also known as the CEE 16A 3-pole blue plug, is a commonly used industrial plug in Europe. This plug is primarily used for heavier electrical equipment and is designed to handle higher current ratings.

The blue plug has three rectangular pins and is used in conjunction with matching blue sockets. It has a nominal current rating of 16 amperes and is often used on construction sites, in workshops, in the industry, and at campsites.

The blue plug and the corresponding socket are designed for safety and durability. They provide a reliable connection and are resistant to harsh conditions. Moreover, the plug offers protection against contact and short circuits.

It is important to note that the blue plug is not compatible with the standard sockets you find at home. If you have a device with a blue plug and want to connect it to a standard socket, you will need a suitable adapter to make the connection.

The use of a blue plug and socket is primarily intended for professional and industrial use. When connecting devices with a blue plug, it is important to follow the appropriate safety regulations and electrical standards.
