Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees.1, 2-core multifunctional power plugThe 2-core multifunctional power plug has only 2 pieces and 2 pins, but each standard is different. For example, here, there are 2 pieces of multifunctional power plug in China and 2 pins in Europe.2,3-core multifunctional power plugThree-core multipurpose power plug is a multipurpose power plug with three plugs and three pins. From the name point of view, the multi-functional power plug only has one more grounding hole than the dual-core multi-functional power plug, but the structure of the three-core multi-functional power plug is much more complicated than the multi-functional power plug, because the internal size and diameter of this multi-functional power plug have great requirements. However, it also allows the length and spacing of the pins of the multifunctional power plug to be improved, which can effectively improve the safety of the multifunctional power plug.3. Multi-core multifunctional power plugThe structure of multi-core multi-function power plug is more complicated than that of three-core multi-function power plug. This multi-core multi-function power plug can only meet the requirements of four-core or five-core customers. Although this multi-core multi-function power plug is complex, its safety is not much different from that of the three-core multi-function power plug, so whether it needs to be selected according to the actual needs of this product.The above content comes from multi-function power plug manufacturer.
