The IP (International PROTECTION) protection system is drafted by IEC (INTERNATIONALELECTROTECHNICAL COMMISSION). Such as the degree of protection IP54, IP for the marked letters, the number 5 for the first marked number, 4 for the second mark number. The first mark indicates the contact protection and the protection level of the foreign object, and the second mark indicates the degree of protection against water.
The first marker number indicates the contact protection and the protection level of the foreign object (protection range), expressed by the following numbers:
0 - no protection.
1 - Protection of 50mm diameter and larger solid outer body.
2 - protective 12.5 mm diameter and larger solid outer body.
3 - Protection of 2.5mm diameter and larger solid outer body.
4 protection 1.0mm diameter and larger solid outside body.
5 - Dust dust can not completely prevent dust from entering, but the amount of dust entering does not cause damage to the equipment.
6 - dust closed completely prevent foreign objects from intruding, and can completely prevent dust from entering.
The second marker number indicates the degree of protection (protection range), expressed by the following numbers:
0 - no protection.
1 - Water droplets protect the vertical drop of water droplets should not cause damage.
2 - Protective water drops When the cabinet is tilted to any angle of 15 degrees, the vertical drop of water droplets should not cause damage.
3 - Protective water sprayed from the vertical line on both sides of the 60-degree angle of water should not cause damage.
4 - Water splashing water from each direction should not cause damage.
5 - Irradiated water sprayed from each direction to the nozzle of the cabinet should not cause damage.
6 - to prevent the strong water from each direction against the cabinet of the strong water should not cause damage.
7 - Protection Short-term flooding When immersed in water under standard pressure for a short period of time, make sure that damage is not caused by water.
8-PROTECTION Long-term immersion can be immersed in water under certain conditions to ensure that damage is not caused by water.
