PROMULGATOR: TAIXI DATE: 2019-03-27
Industrial plugs and sockets, commonly used specifications, according to IEC60309 standard (International Electrotechnical Organization Standard) and China (GB standard) according to current, divided into 16A, 32A, 63A, 125A.
The United States has its own UL standard. According to American standards, the current specifications for industrial plugs and sockets are 20A, 30A, 60A, 100A.
Regardless of Europe, China, and the United States, although the standards are different and the current specifications are different, these products are compatible. The following are compatible current specifications.
IEC and GB standard 16A products are compatible with US UL standard 20A industrial plug and socket products
IEC and GB standard 32A products are compatible with American UL standard 30A industrial plug and socket products
IEC and GB standard 63A products are compatible with American UL standard 60A industrial plug and socket products
IEC and GB standard 125A products are compatible with US UL standard 100A industrial plug and socket products
Product color and voltage relationship:
According to international standards:
In industrial plugs and sockets, blue indicates a product with a voltage of 230V.
In industrial plugs and sockets, red indicates a product with a voltage of 400V.
In industrial plugs and sockets, the all-white product represents a 50V ultra-low voltage product.
In industrial plugs and sockets, the purple product represents 20V ultra low voltage products.
According to the number of product poles (that is, the number of stylus / jack number), divided into
3P(2P +E ) English means 3Pole or Single Phase---This is also called single-phase plug, which means FireWire + Neutral + Ground
4P (3P + E) English means 4Pole or 3Phase --- This is a three-phase plug, indicating three live lines + ground
5P(3P+N+E) English means 5Pole or 3Phase----This is a three-phase plug and socket, indicating three live wires + zero wire + ground wire
Please pay attention to customers who frequently communicate with foreign friends, 4P and 5P are Three Phase, which means that they are all three-phase AC.
Grounding point:
In the product specification, there is a specification of 6h or 12h. Here, h represents the grounding pin and the clock control. The grounding pin is at the corresponding point on the clock, and is taken from the first letter of the English word hour.
According to international standards, 3h, that is, the grounding point is 3 o'clock plug and socket, dedicated to the ship. Such as reefer containers, cargo terminals and other places.
Our products are classified into IP44 and IP67 according to the degree of protection.
According to international standards, the degree of protection is divided into two parts. The first part is dustproof. It is divided into numbers 1-6 according to the degree of protection from low to high. The higher the number, the higher the protection level. The second part is waterproof, divided into numbers 1-8 according to the degree of protection from low to high. The higher the number, the higher the protection level.
IP44
The first number 4 in IP44 indicates: solids with a diameter of >1.0 mm/lines or sheets with a diameter greater than 1 mm and solids with a diameter of more than 1 mm
The second number 4 in IP44 means: splash-proof / splashing in any direction should have no harmful effects
IP67
The first number 6 in IP67 means: dust/no dust entry
The second number 7 in IP67 indicates that after entering the water at the specified pressure for a specified period of time, the amount of water entering should have no harmful effects.
