The difference between the industrial plug and the household plug can be distinguished from the appearance first. The industrial power is generally three-phase electricity, so the plug is generally three-phase four-plug, and the household electric power is two-phase electric, so Two plugs or three plugs.

In addition, the difference in the use environment is also very large, household plugs, as the name suggests, are mostly used in family houses. Industrial plugs are different. It is widely used in iron and steel smelting, petrochemical, electric power, electronics, railways, construction sites, airports, mines, mining sites, water supply and drainage treatment plants, as well as ports, terminals, shopping malls, hotels and other industrial and mining industries. enterprise.

Due to the environmental problems of industrial sockets, the safety of industrial plugs is much higher than that of household sockets. The poor quality of plugs and sockets is an important cause of electrical fires. The quality problems of small plugs and sockets will pose serious harm to the personal and property safety of consumers.

Therefore, industrial plugs and sockets have higher requirements in terms of safety. Industrial plugs and sockets are generally divided into 3 cores, 4 cores, 5 cores, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc. Can be divided into IP44, IP67 two, for these are more conventional.

Industrial plug and socket power supply is divided into four types: 16A, 32A, 63A, 125A. The voltage is divided into 40V-45V (purple), 110V-130v (yellow), 200V-250V (blue), 230V-415V (red), 500V ( black).

Due to the difference in current, voltage, protection level and material, you need to consult carefully when buying industrial plugs and sockets.
