The industrial plug-in equipment manufactured in compliance with the CEE standards is characterized by noninterchangeability of various type equipment due to specific construction. The equipment for voltages of 230 and 400 V has its protective contact always in the position of 6 h (the position of number 6 on the clock face). The protective contact is dicker than the phase ones, which makes impossible any phase changing, and thereby a wrong connection. The equipment for the voltage of 24 V has no protective contact, it is designated with violet color. The 230 V equipment is blue color, and the 400 V red colour. Dimensions of the equipment are different for individual rated currents.

Number of poles:
2 P - equipment for single-phase 24 V electric-current consumers
2 P + equipment for single-phase 230 V electric-current consumers
3 P + equipment for symmetric three-phase electric-current consumers (motors)
3 P + N + equipment for asymmetric three-phase electric-current consumers
All the insulation parts are made of high-quality thermoplastic, resistant to strokes and low temperatures. It maintains its form even at the temperature of up to 120 C, it is resistant to aging and chemicals.

There is a choice of plug-in equipment protected against splashing water (IP 447) or waterproof version (IP 677).

Use the industrial plug-in equipment is primarily intended for connection of mobile electric-current consumers in industrial shops, on building sites, in craftsman's workshops, in farming facilities and elsewhere.
