CEE socket and plug 004482000, plug equipment is industrial grade, developed to meet CEE specifications, and because of specific instructions, different types of equipment are not interchangeable. In addition, the unit with voltage of 230V and 400V always has a shielding contact at 6H position (the number 6 is located on the clock face).
In addition, the shielding contact is much thicker than the phase model, and it can't change any phase, resulting in wrong connection. The equipment with 24V voltage has no shielded contact and has purple characteristics. 230 volt equipment is blue and red is designated as 400 volt equipment. This series of equipment has different sizes. The number of poles is 2: one-phase 24V current buyer 2P+ equipment one-phase 230V current buyer 3P+ equipment symmetrical three-phase current buyer (motor).
