Industrial sockets provide a connection to the electrical mains rated at higher voltages and currents than the household plugs and sockets. They are generally used in polyphase systems, with high currents, or when protection from environmental hazards is required. Industrial outlets may have weatherproof covers, waterproofing sleeves, or may be interlocked with a switch to prevent accidental disconnection of an energized plug.
According to the requirement there are range from 16A 3Pin to suite the projects.
