Terko socket


The collection of plugs and sockets focuses on the following two categories:

Plugs and sockets that are used for domestic purposes. That means 220-240 Volt / 10-16 Amp, or 100-125 Volt / 15-20 Amp devices that can be found in homes and offices, including, multi-plugs, adapter plugs, power cords that come with various types of appliance couplers.

Plugs and sockets for single phase
heavy duty, or three- phase applications in homes and/or workshops. The three-phase section is restricted to 400 Volt / 32 Amp, or US: 250 Volt / 60 Amp, or 480 Volt / 30 Amp.

Both modern and classical material is represented in the collection.
  Excluded are:
(i)   nearly all devices for less than 100 Volt,
(ii)  typical direct current plugs and sockets, and
(iii) material for 'heavy' industrial applications.

There are items that are clearly missing in the collection, for example country-specific non-standard plugs and sockets, and obsolete material. See also Missing Objects.
