General specifications of industrial plugs and sockets:
According to IEC60309 (International Electrotechnical Commission Standard) and China (GB Standard), the current is divided into 16A, 32A, 63A, and 125A.
According to the American user interface standard, the current is 20A, 30A, 60A, 100A.
Compatibility between different specifications:
Products rated at 16A according to IEC and GB standards are compatible with industrial plug and socket products rated at 20A according to the American UL standard.
Products rated at 32A according to IEC and GB standards are compatible with industrial plug and socket products rated at 30A according to the American UL standard.
Products rated at 63A according to IEC and GB standards are compatible with industrial plug and socket products rated at 60A according to the American UL standard.
Products rated at 125A according to IEC and GB standards are compatible with industrial plug and socket products rated at 100A according to the American UL standard.
Standard color and voltage differences:
Blue indicates a voltage of 230V.
Red indicates a voltage of 400V.
White products represent 50V ultra-low voltage products.
Purple products represent 20V ultra-low voltage products.
Labeling and meaning of the product pole number:
3P (2P + E) means 3 poles or single-phase: line + neutral + ground.
4P (3P + E) means 4 poles or 3-phase, which is three lines + ground.
5P (3P + N + E) in English means 5 poles or 3-phase, which means three voltage wires + neutral + ground.
Industrial plugs and sockets are dustproof, waterproof, splash-proof, corrosion-resistant, fault-resistant, drip-proof, flame-retardant, resistant to high temperatures, and aging-resistant. The main contact parts are made of H59-1 copper. The color of the shell indicates different voltages and frequencies, and the positions, diameters, and number of poles of different connectors are different to prevent incorrect insertion.
